MANAGEMENT'S DISCUSSION AND ANALYSIS

March 31, 2024

INTRODUCTION

This Management's Discussion and Analysis ("MD&A") for Almaden Minerals Ltd. ("Almaden" or the "Company") has been prepared based on information known to management as of May 14, 2024. This MD&A is intended to help the reader understand, and should be read in conjunction with, the condensed consolidated interim financial statements of Almaden for the financial period ended March 31, 2024 and supporting notes. The condensed consolidated interim financial statements have been prepared in accordance and compliance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board.

Management is responsible for the preparation and integrity of the Company's condensed consolidated interim financial statements, including the maintenance of appropriate information systems, procedures and internal controls. The audit committee of the board of directors of the Company (the "Board") meets with management regularly to review the Company's condensed consolidated interim financial statements and MD&A, and to discuss other financial, operating and internal control matters.

All currency amounts used in this MD&A are expressed in Canadian dollars unless otherwise noted.

The Company's common stock is quoted on the on the Toronto Stock Exchange under the symbol "AMM" and the OTCQB under the symbol "AAUAF".

This MD&A contains forward looking statements that involve numerous risks and uncertainties. The Company continually seeks to minimize its exposure to business risks, but by the nature of its business and exploration activities and size, will always have some risk. These risks are not always quantifiable due to their uncertain nature. Should one or more of these risks and uncertainties, including those described under the heading "Risk factors" in our Annual Information Form ("AIF") and those set forth in this MD&A under the headings "Cautionary Notes Regarding Forward-Looking Statements" materialize, or should underlying assumptions prove incorrect, then actual results may vary materially from those described in forward- looking statements.

ADDITIONAL INFORMATION

The Company's financial statements, MD&A and additional information relevant to the Company, including the Company's AIF for the year ended December 31, 2023, can be found on SEDAR at www.sedar.com, on the EDGAR section of the SEC's website at www.sec.gov, and/or on the Company's website at www.almadenminerals.com.

QUARTERLY HIGHLIGHTS

Legal Disputes

On February 22, 2023 the Company announced that Economia had made a submission to the second district court in Puebla State (the "District Court"), seeking to deny the two mineral title applications which were first made by Almaden in 2002 and 2008 (the "Submission") and which underpin the Ixtaca deposit. The Submission claimed that the mineral title applications contain technical faults, despite Economia's previous statements to the contrary and its acceptance of the mineral title applications and grant of the mineral titles in 2003 and 2009. By alleging technical faults in the mineral title applications, Economia appeared to be arbitrarily seeking to deny the grant of the mineral titles and avoid the indigenous consultation ordered by the February 2022 decision of Mexico's Supreme Court ("SCJN").

Later, on April 13, 2023, the Company announced that the District Court ruled that the Submission formally complied with the SCJN decision. The Company and some local community members filed separate

1

appeals of the District Court decision with the Federal Appeals Court ("TCC"), and on October 16, 2023 the Company reported that the TCC dismissed all of the appeals filed by the Parties, and ruled the Submission is compliant with the 2022 decision of the SCJN, since the SCJN decision did not formally prevent Economia from reviewing the technical aspects of the mineral title applications. The TCC ruling did not address the validity of the Submission and therefore safeguarded the Company's right to challenge the substance and legality of the Submission through the Mexican Federal Administrative Court ("TFJA").

Subsequent to the Submission, the Company had initiated legal action in the TFJA and on October 16, 2023 announced that the TFJA granted a definitive injunction in relation to the Submission, which prevents Economia from releasing the mineral rights covered by Almaden's mineral title applications to third parties while the trial continues, anticipated to last approximately 18 months in total.

As a result of the above, the Company believes that any rights held by Almaden relating to the Ixtaca project are now based on mineral title applications which have been denied by Economia, through its issuance of the Submission. The Company is in the process of disputing this denial through the TFJA.

In addition, on December 13, 2023, the Company delivered to Mexico a Request for Consultations in accordance with the Comprehensive and Progressive Agreement for Trans-Pacific Partnership ("CPTPP") relating to an investment dispute with Mexico. Almaden sent the Request for Consultations to Mexico's General Directorate of Legal Consultancy for International Trade (Dirección General de Consultoría Jurídica de Comercio Internacional).

The Company has suffered substantial harm arising out of Mexico's conduct in breach of its investment protection obligations under the CPTPP, including (without limitation):

  • Economia's declaration that the Project's mineral titles were ineffective, or void;
  • Economia's reassessment of the original applications for the mineral titles holding them to be deficient and unfeasible, contradicting the position previously adopted by it, and violating the
    Company and its subsidiary's right to amend or supplement the mineral title applications; and
  • the Mexican Secretariat of Environment and Natural Resources' (Secretaría del Medio Ambiente y Recursos Naturales, "SEMARNAT") delay in issuance and ultimate refusal to issue the environmental permit (Manifiesto de Impacto Ambiental) for the Ixtaca project.

The Request for Consultations enables the Company to initiate arbitration should an amicable resolution of the dispute with the Mexican government not be reached. The filing of the Request for Consultations initiates a six-month consultation period between the parties, during which they are to attempt to amicably settle the dispute. If no settlement is reached in that six-month period, the Company may then initiate international arbitration proceedings against Mexico in accordance with the CPTPP after serving a notice of intent to submit claims to arbitration. On December 29, 2023, Mexico acknowledged receipt of the Request for Consultations and stated that it would propose dates for a consultation meeting in the near future.

On March 14, 2024, the Company delivered to Mexico written notice of its intention to submit a claim ("Claim") to arbitration against Mexico (the "Notice") in accordance with Article 9.19.3 of the CPTPP. This Notice was delivered by Almaden together with Almadex Minerals Ltd. ("Almadex"), on behalf of themselves and their Mexican subsidiaries.

Amongst other things, the Notice sets out the factual background of the dispute as well as the legal basis of the resulting Claim, the provisions of the CPTPP that Mexico has breached, and the relief sought. The damages relating to the Almaden and Almadex Claim will be for no less than US$200 million, in the aggregate.

The Notice enables the Company to initiate arbitration should an amicable resolution of the dispute with the Mexican government not be reached. The filing of the Notice must precede initiation of arbitration by a minimum of 90 days.

In good faith and in the spirit of cooperation, through its March 14, 2024 notice Almaden invited Mexico once again to engage in discussions and negotiations with a view to achieving an amicable resolution of the dispute. On May 9, 2024 Mexico proposed dates for a meeting at the end of May. The Company confirms that it is taking all necessary actions to preserve its rights and protect its investments in Mexico. The Company's desire is for all parties to reach a mutually acceptable outcome swiftly and amicably. If such an outcome is not achieved during consultations, the Company expects it will have no alternative but to pursue its claims before an arbitral tribunal and seek full compensation for damages the Company has suffered as a result of Mexico's acts and omissions. The Company retained international arbitration counsel at Boies Schiller Flexner LLP to advise and will consider any other actions necessary to ensure its rights are preserved.

Further background on these legal matters is provided below in the section titled "Risks and Uncertainties".

NYSE Listing

As previously announced, Almaden ceased being in compliance with the continued listing standards of the NYSE American exchange because its securities were trading for a low price per share for a substantial period of time, which NYSE American determines to be a 30-trading-dayaverage price of less than US$0.20 per share. The Company's continued listing on the NYSE American exchange was predicated on it demonstrating sustained price improvement within a reasonable period of time which was determined to be no later than April 19, 2024.

In view of the continued uncertainty relating to the Ixtaca project and the Company's wish to provide predictability to shareholders, the Company voluntarily delisted from the NYSE American exchange, and is now trading in the U.S. on the OTCQB Marketplace under symbol "AAUAF". The Company also continues to trade on the TSX exchange under symbol "AMM".

OVERALL PERFORMANCE

Overview

Company Mission and Focus

The Company's goal is to advance the Ixtaca gold-silver deposit to become a low-cost, modern mine which makes a positive social difference.

Qualified Person

Morgan Poliquin, P.Eng., a "Qualified Person" as defined in National Instrument 43-101Standards of Disclosure for Mineral Projects ("NI 43-101") and the President, Chief Executive Officer and a director of Almaden, has reviewed and approved the scientific and technical information in this MD&A. Much of the scientific and technical contents in this MD&A are derived from the Technical Report titled "Ixtaca Gold- Silver Project, Puebla State, Mexico, NI 43-101 Technical Report on the Feasibility Study" with an effective date of January 24, 2019 (the "FS"). The independent Qualified Persons responsible for preparing the FS are set out below under the heading, "Qualified Persons, Sample Preparation, Analyses, Quality Control and Assurance".

Use of the Terms "Mineral Resources" and "Mineral Reserves"

All capitalized terms used but not defined in this MD&A have the meanings given to them in NI 43-101 and the 2014 CIM definitions Standards on Mineral Resources and Reserves (the "CIM Standards").

Any reference in this MD&A to Mineral Resources does not mean Mineral Reserves.

Under CIM Standards, a Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by a Preliminary Feasibility Study or a Feasibility Study. This study must

3

include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that extraction could reasonably be justified. A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined.

A Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling.

Mineral Resources are sub-divided, in order of increasing geologic confidence, into Inferred, Indicated and Measured categories. An Inferred Mineral Resource has a lower level of confidence than that applied to an Indicated Mineral Resource. An Indicated Mineral Resource has a higher level of confidence than an Inferred Mineral Resource but has a lower level of confidence than a Measured Mineral Resource.

An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An Inferred Mineral Resource must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

An Indicated Mineral Resource has a higher level of confidence than an Inferred Mineral Resource but has a lower level of confidence than a Measured Mineral Resource, and may only be converted to a Probable Mineral Reserve.

A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.

The disclosure in this MD&A has been prepared in accordance with the requirements of the securities laws in effect in Canada which differ from the requirements of United States securities laws. All mining terms used herein but not otherwise defined have the meanings set forth in National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). Accordingly, information contained in this MD&A containing descriptions of the Company's mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United States federal securities laws and the rules and regulations thereunder For example, the terms "Mineral Reserve," "Proven Mineral Reserve" and "Probable Mineral Reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves under United States rules. "Indicated Mineral Resource" and "Inferred Mineral Resource" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all, or any part, of an Indicated Mineral Resource or Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of Feasibility Studies or Pre-Feasibility Studies, except in rare cases. Investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable.

Ixtaca (Tuligtic) - Mexico

The following is a brief description of the mineral project in which the Company has an interest, subject to the legal proceedings described under "Risk and Uncertainties - Title to mineral properties". Almaden does not currently hold title to the mineral concessions underlying the Ixtaca Deposit and there is no guarantee that it will in the future. Additional technical information can be obtained from Almaden's website at www.almadenminerals.comand in the FS, which is available under the Company's SEDAR profile at www.sedar.com.

Location and Ownership

The Company holds an interest in the Ixtaca Project described below and under "Risk and Uncertainties - Title to the mineral properties", subject to a 2% net smelter return ("NSR") royalty held by Almadex. The Ixtaca Project lies within the Trans Mexican Volcanic Belt about 120 kilometres southeast of the Pachuca gold/silver deposit, which has reported historic production of 1.4 billion ounces of silver and 7 million ounces of gold. The Tuligtic property, located in Puebla State, was acquired by staking in 2001 following prospecting work carried out by the Company in the area. Since that time, Almaden has had agreements to develop the property with three separate parties, all of whom relinquished all rights to the property and none of whom conducted work on the Ixtaca zone. The Ixtaca zone is located along a trend of shallowly eroded epithermal systems that Almaden has identified in eastern Mexico. Almaden does not currently hold title to the mining concessions underlying the Ixtaca Deposit and there is no guarantee that it will in the future. The nature of the Company's interest in the Ixtaca Project is described in the section below entitled "Title to Mineral Properties".

Claims and Title

Almaden's interest with respect to the Tuligtic Property is held by Minera Gorrion S.A. de C.V., a subsidiary of Almaden, through the holding company, Puebla Holdings Inc., and is subject to a 2% NSR in favour of Almadex.

To maintain a claim in good standing in Mexico, the holder is required to meet annual exploration or exploitation expenditure requirements. Given that the Original Concessions have reverted to application status, the Company has been advised that currently there are no taxes or expenditure requirements relating to them.

Almaden does not currently hold title to the mineral concessions underlying the Ixtaca Deposit and there is no guarantee that it will in the future. The Tuligtic Property was identified by Almaden in 2001, following the recognition of surficial clay deposits that were interpreted to represent high-level epithermal alteration. The Cerro Grande concession was granted to the Company in 2003, and the Cerro Grande 2 concession was granted to the Company in 2009. The Property originally consisted of approximately 14,000 hectares (the "Original Concessions"), as shown below:

Legal Dispute

On April 7, 2015, the Ejido Tecoltemi, a community granted communal agrarian lands by the Mexican Government and whose lands (the "Ejido Lands") overlapped with the southeastern portion of the Company's original mineral concessions, filed an Amparo in a lower court in Puebla State, claiming that Mexico's mineral title system is unconstitutional because Indigenous consultation is not required before the granting of mineral title (the "Amparo" or "Mineral Title Lawsuit"). The Amparo was against the Mexican government (President, Congress, Ministry of Economy, Directorate of Mines, Mining Registry Office), and used the Company's two Original Concessions covering the Ixtaca Project as the subject matter of the Amparo. Almaden, through its Mexican subsidiary Minera Gorrión, was therefore considered an interested party in the Amparo. The Original Concessions covered Almaden's Ixtaca Project and the Ejido Lands. The Ejido Lands overlapped approximately 330 ha of the far southeastern corner of the Original Concessions.

Shortly after the Amparo was filed in April 2015, the lower court in Puebla State ordered the suspension of Almaden from conducting exploration and exploitation work over those portions of the Original Concessions which overlap with the Ejido Lands.

5

Mineral tenure over the Ejido Lands is not material to the Ixtaca Project. The Ejido Lands do not overlap the Ixtaca Project or its environmental or social area of impact. Almaden has never tried to negotiate access to the Ejido Lands, never conducted exploration work on the Ejido Lands, and has no interest in conducting any future exploration or development work over the Ejido Lands. The Ejido Lands are in a different drainage basin than the Ixtaca Project and the Company does not need to travel though the Ejido Lands to access the Ixtaca Project.

On April 15, 2019, the lower court in Puebla State ruled that Mexico's mineral title system is unconstitutional. The Company's concessions were ruled to be illegal, but the mineral rights over that land were ordered to be held for Almaden until such time as indigenous consultation could be completed.

Under Mexican law, any decisions in the Amparo, such as the April 15, 2019 lower court ruling, are granted in a provisional manner and only become final once the decisions are no longer subject to further appeal. The Superior (Collegiate) Court accepted the appeals of each of the Mexican Congress, Senate, Secretary of Economy and mining authorities, as well as Almaden as an interested party, against the April 15, 2019 provisional lower court decision in the Amparo.

On April 14, 2021, the Company announced that the Collegiate Court issued its decision on the Amparo, stating that it does not have the necessary authority to rule on the appeals. The case passed directly to the Supreme Court of Justice of Mexico ("SCJN").

In early 2022, the SCJN ruled that the Mexican mineral title law is constitutional, but that Economia should have provided for a consultation procedure with relevant indigenous communities prior to issuing mineral titles to the Company. The SCJN ordered Economia to declare Almaden's mineral titles ineffective, or void, and to revert them to application status in order to facilitate indigenous consultation.

The SCJN decision provided guidance to Mexican authorities regarding the procedures required to be followed by those authorities in the follow-up to its decision and performance of indigenous consultation. The decision also clarified that unless there is a significant impact on the rights of an indigenous community caused by the granting of the mineral title, such as relocation or something similar, title issuance is not dependent upon the consent of any indigenous community. The lower court in Puebla State was responsible for ensuring that the SCJN decision was properly implemented.

On July 4, 2022, the Company announced that Economia was officially notified of the SCJN decision and in turn notified Almaden that the Company's mineral titles relating to the Ixtaca Project were "ineffective", or void. Almaden understood this to mean that the mineral title reverted to application status and that these applications remained effective and preserved the mineral rights for Almaden but did not allow the Company to engage in exploration until such time as Economia completed its court-ordered indigenous consultation.

On February 22, 2023, the Company announced that Economia made a submission to the lower court in Puebla State seeking to deny the two mineral title applications which were first made by Almaden in 2002 and 2008 (the "Submission"). The Submission claimed that the applications contained technical faults, despite Economia's previous statements to the contrary and its acceptance of the mineral title applications and grant of the mineral titles in 2003 and 2009. By alleging technical faults in the mineral title applications, Economia appeared to be arbitrarily seeking to deny the grant of the mineral titles and avoid the indigenous consultation ordered by the 2022 decision of the SCJN. Such consultation would have been welcomed by both the Company and surrounding community members.

On April 13, 2023, Almaden reported that the lower court in Puebla State ruled that the Submission formally complied with the SCJN decision. However, the court ruling appeared to rely heavily on Economia's Submission regarding the Company's 2002 and 2008 title applications, and in its decision the court did not provide arguments to address the Company's challenge of the Submission.

Almaden and local community members filed separate appeals of this decision to the Federal Appeals court ("TCC"), which in October 2023 dismissed all of the appeals filed by the Parties and confirmed the Submission is compliant with the 2022 decision of the SCJN, since the SCJN decision did not formally prevent Economia from reviewing the technical aspects of the mineral title applications.

6

However, the TCC ruling did not address the validity of the Submission and therefore safeguarded the Company's right to challenge the substance and legality of the Submission through the Mexican Federal Administrative Court ("TFJA").

Subsequent to the Submission, the Company had initiated legal action in the TFJA and on October 16, 2023 announced that the TFJA granted a definitive injunction in relation to the Submission, which prevents Economia from releasing the mineral rights covered by Almaden's mineral title applications to third parties while the trial continues, anticipated to last approximately 18 months in total.

On December 13, 2023, the Company delivered to Mexico a Request for Consultations in accordance with the Comprehensive and Progressive Agreement for Trans-Pacific Partnership ("CPTPP") relating to an investment dispute with Mexico. Almaden sent the Request for Consultations to Mexico's General Directorate of Legal Consultancy for International Trade (Dirección General de Consultoría Jurídica de Comercio Internacional).

The Company has suffered substantial harm arising out of Mexico's conduct in breach of its investment protection obligations under the CPTPP, including (without limitation):

  • Economia's declaration that the Project's mineral titles were ineffective, or void;
  • Economia's reassessment of the original applications for the mineral titles holding them to be deficient and unfeasible, contradicting the position previously adopted by it, and violating the
    Company and its subsidiary's right to amend or supplement the mineral title applications; and
  • the Mexican Secretariat of Environment and Natural Resources' (Secretaría del Medio Ambiente y Recursos Naturales, "SEMARNAT") delay in issuance and ultimate refusal to issue the environmental permit (Manifiesto de Impacto Ambiental) for the Ixtaca project.

The Request for Consultations enables the Company to initiate arbitration should an amicable resolution of the dispute with the Mexican government not be reached. The filing of the Request for Consultations initiates a six-month consultation period between the parties, during which they are to attempt to amicably settle the dispute. If no settlement is reached in that six-month period, the Company may then initiate international arbitration proceedings against Mexico in accordance with the CPTPP after serving a notice of intent to submit claims to arbitration. On December 29, 2023, Mexico acknowledged receipt of the Request for Consultations and stated that it would propose dates for a consultation meeting in the near future.

On March 14, 2024, the Company delivered to Mexico written notice of its intention to submit a claim ("Claim") to arbitration against Mexico (the "Notice") in accordance with Article 9.19.3 of the CPTPP. This Notice was delivered by Almaden together with Almadex, on behalf of themselves and their Mexican subsidiaries.

Amongst other things, the Notice sets out the factual background of the dispute as well as the legal basis of the resulting Claim, the provisions of the CPTPP that Mexico has breached, and the relief sought. The damages relating to the Almaden and Almadex Claim will be for no less than US$200 million, in the aggregate.

The Notice enables the Company to initiate arbitration should an amicable resolution of the dispute with the Mexican government not be reached. The filing of the Notice must precede initiation of arbitration by a minimum of 90 days. On May 9, 2024, Mexico responded to the Company's Request for Consultations and proposed a meeting at the end of May.

Feasibility Study and Updated Resource Estimate

On December 11, 2018, Almaden announced the results of an independent Feasibility Study titled "Ixtaca Gold-Silver Project, Puebla State, Mexico NI 43-101 Technical Report on the Feasibility Study" (defined above as the "FS"). The FS was subsequently filed on SEDAR on January 24, 2019. An update to the FS was filed on SEDAR on October 3, 2019.

Geology and Mineral Resource Estimate

The Ixtaca deposit is an epithermal gold-silver deposit, mostly occurring as anastomosing (branching and re-connecting) vein zones hosted by limestone and shale basement rocks with a minor component of disseminated mineralisation hosted in overlying volcanic rocks. The wireframe models constructed to define the overall vein zones therefore contain interspersed irregular zones of barren limestone dilution. In this FS the limestone unit hosts 75% of the metal produced, the volcanic unit hosts 12% and the black shale unit hosts 13% on a gold-equivalent basis. The Mineral Resources for Ixtaca are presented in Table 2.

  1. Ixtaca Mineral Resources Estimate have an effective date of 8 July 2018. The Qualified person for the estimate is Gary Giroux, P.Eng.
  2. Base Case 0.3 g/t AuEq Cut-Off grade is highlighted. Also shown are the 0.5, 0.7 and 1.0 g/t AuEq cut-off results. AuEq calculation based average prices of $1250/oz gold and $18/oz silver. The Base Case cut-off grade includes consideration of the open pit mining method, 90% metallurgical recovery, mining costs of $1.82/t, average processing costs of $11.7, G&A costs of $1.81/t
  3. Mineral Resources are reported inclusive of those Mineral Resources that have been converted to Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  4. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal or other relevant issues. The Mineral Resources have been classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves in effect as of December 11, 2018.
  5. All figures were rounded to reflect the relative accuracy of the estimates and may result in summation differences.

Mine Plan

The Ixtaca gold-silver project is planned as a typical open pit mining operation using contractor mining. Initial production will ramp up to a mill feed rate of 7,650 tonnes per day followed by an expansion to 15,300 tonnes per day from Year 5 onwards.

An ore control system is planned to provide field control for the loading equipment to selectively mine ore grade material separately from the waste.

Mining operations will be based on 365 operating days per year with three 8 hour shifts per day.

Processing

The FS reflects the Rock Creek process plant which has been purchased by Almaden. Run of mine ore will be crushed in a three-stage crushing circuit to -9 mm.

The FS also incorporates ore sorting, test work for which has shown the ability to separate barren or low grade limestone host rock encountered within the vein swarm from vein and veined material (see Almaden news release of July 16th 2018). Product from the secondary crusher will be screened in to coarse (+20mm), mid-size (12 to 20 mm), and fine (-12mm) fractions. Coarse and mid-size ore will be sorted by an XRT ore sort machine to eject waste rock. Fine ore will bypass the ore sorting and is sent directly to the mill.

Ore sort waste from Limestone and Black Shale is below waste/ore cutoff grade and is placed in the waste rock dump. Ore sort 'waste' from the Volcanic unit is low grade ore and will be stockpiled for processing later in the mine life. Ore sorting pre-concentration increases the mill feed gold and silver grades by 32% and 31% respectively compared to run of mine (ROM) grades. Table 3 shows ROM grades with ore sort waste removed from the ROM, and the resulting mill feed.

Crushed ore is transported to the grinding circuit by an over land conveyor. Grinding to 75 microns is carried out with ball milling in a closed circuit with cyclones. Cyclone underflow is screened and the screen undersize is treated in semi-batch centrifugal gravity separators to produce a gravity concentrate.

The gravity concentrate will be treated in an intensive leach unit with gold and silver recovered from electrowinning cells.

The cyclone overflow will be treated in a flotation unit to produce a flotation concentrate. After regrinding the flotation concentrate leaching will be carried out in 2 stages. CIL leaching for 24 hours will complete gold extraction, followed by agitated tank leaching to complete silver leaching. A carbon desorption process
