- Drilling highlights significantly higher grades at both deposits and three distinct parallel mineralised lodes at Regal with mineralisation starting from surface
- Extensive metallurgical test work and previous trial mining and milling showed recoveries of over 91% from conventional carbon in leach ore processing with a high gravity component
- The updated geological model for Boorara Stage 1 is well advanced and is expected to be released with the mine optimisation, design and economic evaluation in the current March Quarter 2020 2
Commenting on the latest results from Boorara, Horizon Managing Director Mr Jon Price said:
"The results from Regal and Crown Jewel continue to demonstrate the considerable potential at Boorara with high grades intercepted at mineable widths and the ore starting at surface. The drilling has intercepted both the main NNW striking zones and multiple flat cross cutting vein sets and has certainly exceeded our expectations. "
"The focus is now on delivering a robust model, mine optimisation and economic evaluation to meet our objective of bringing Stage 1 of Boorara into production in 2020 and unlocking further value from the larger scale development being assessed as part of the Feasibility Study due out in December Quarter 2020. "

Overview
Horizon Minerals Limited (ASX: HRZ) ("Horizon" or the "Company") is pleased to announce further excellent reverse circulation ("RC") drilling results from the 100% owned Boorara gold project located 10km east of Kalgoorlie-Boulder in the heart of the Western Australian goldfields (Figure 1).
Figure 1: Kalgoorlie Regional Project area location and surrounding infrastructure
During the December Quarter 2019, the Company completed 18,000m of infill Reverse Circulation (RC) drilling on 4m x 10m (south) and 5m x 10m (north) drill spacing to a maximum depth of 54m at the Royal (southern stockwork), Crown Jewel (central) and Regal (northern stockwork) deposits (Figures 1 and 2).

Project Summary and Geology
The Boorara gold project is located on granted Mining Leases 1km southwest of the Nimbus site where established offices are connected to mains power and a production water supply from the Stoneville bore field.
The deposit is hosted in a typical quartz dolerite comprising a sheeted quartz vein array system with bounding shear zones and late stage cross faults. Mineralisation occurs as:
- Northwest dipping sheeted and stockwork quartz-carbonate vein arrays within the quartz dolerite host rocks
- Steeply dipping zones along sheared geological contacts trending to the north-northwest
A significant amount of RC and diamond drilling has been completed at Boorara over the last 10 years with the project hosting a current Mineral Resource Estimate totalling 16.45Mt grading 0.96g/t Au for 507,000oz at a 0.5g/t Au cut-off grade.1
Gold mineralisation is associated with pyrite and arsenopyrite with alteration halos of iron carbonate, sericite and bleaching. The current resource covers a strike length of over 1.8km and widths of over 250m and remains open along strike to the south and north and at depth.
A small scale trial pit to 20m depth was mined in the Royal area at Boorara in 2016, with ore up to 15m wide mined on 2.5m high flitches 2. A close spaced grade control program undertaken prior to mining yielded planned trial pit grades well above the global resource grade of 1g/t 1. Ore mined from the trial pit was processed at FMR Investments' Greenfields Mill in Coolgardie which reconciled at 30,239 tonnes at 1.73g/t of high grade ore, with an additional 13,095 tonnes at 0.68g/t of low grade still stockpiled at Boorara.
Depth of weathering can vary from less than 10m in the northern area and over 60m in the southern area. The ore is free milling with gold recoveries > 90% with a high gravity recoverable component as demonstrated through extensive metallurgical test work and trial mining and ore processing. 2
The aim of the current grade control program was to further test the grade uplift potential on a larger scale and enable a new geological model to be compiled for mine optimisation, design and economic analysis. In addition, the data will be used to update the global resource model as part of the Feasibility Study underway for the larger scale development to underpin a standalone processing facility at Boorara or collaboration with neighbouring companies.
The results received from the Regal and Crown Jewel deposit (Figures 2 - 8) demonstrate the higher gold grades resulting from this close spaced grade control drilling.
Three parallel lodes were grade control drilled at Regal, with all lodes at a 060⁰ azimuth and -60⁰ dip on a 5m x 10m drill spacing. Near vertical quartz dolerite lodes with multiple quartz vein arrays were intercepted as well as multiple flat NW dipping quartz lodes.
At Crown Jewel, vertical grade control holes (4mx10m drill spacing) intercepted the quartz dolerite lode from surface with multiple vein arrays.

Next Steps 1
All results will now be used to compile an independent geological model for Boorara Stage 1 comprising all three deposits. The model will be generated by BM Geological Services Pty Ltd, a local geological consultancy who has significant experience in the region and with this style of mineralisation. On completion of the model, a mine optimisation and design will be undertaken across three starter pits to generate a mining inventory for mine scheduling and economic evaluation.
Significant metallurgical test work has been completed and previous mining and milling data demonstrated expected gold recoveries of >91% with a high gravity recovery component.
Discussions with mining, haulage and toll milling contractors are well advanced and all statutory approvals have been submitted to meet the Company's objective to be mining at Boorara in the June Quarter 2020 and toll milling in the September Quarter 2020.

- RC recovery and meterage was assessed by comparing drill chip volumes for individual meters. Estimates of sample recoveries were recorded. Routine checks for correct sample depths are undertaken every RC rod (6m). RC sample recoveries were visually checked for recovery, moisture and contamination. The cyclone was routinely cleaned ensuring no material build up.
- Due to the generally good/standard drilling conditions around sample intervals (dry) the geologist believes the samples are representative, some bias would occur in the advent of poor sample recovery which was logged where rarely encountered.
- No sample bias has been identified to date.

- The Boorara Project is located approximately 17km east-southeast of Kalgoorlie, 2km west of Nimbus and 6km north-northwest of Golden Ridge. The Boorara project is situated within mining leases M26/29, M26/277 and M26/318 accessed from the Kalgoorlie-Bulong Road via an unsealed haul road. The tenements are located within the Hampton Hill Pastoral Station.
- Normal Western Australian state royalties apply. A third party royalty of $1/t is payable to a maximum of $1 million on M26/277. A third party royalty based on production milestones is payable on M26/29, M26/318 & M26/161 as below;
25,000 ounces gold production - 375 ounce royalty payable
50,000 ounces gold production - 375 ounce royalty payable
75,000 ounces gold production - 375 ounce royalty payable
100,000 ounces gold production - 375 ounce royalty payable
- Situated within the Boorara Project area are the reserves associated with the Boorara townsite. Proposed open pit operations will not impact on the reserves. The location of waste dumps will be sited so as to avoid mineral resources, exploration targets and to work with other mining infrastructure associated with the Nimbus operations located within 2km of the proposed Boorara open pits. MRP purchased the Nimbus property on 8th September 2011 from Kalgoorlie Ore Treatment Company Pty Ltd (KOTC). The tenements are held by KOTC, a wholly owned subsidiary of MacPhersons Resources Ltd.

diamond holes for 2,609m. Geological mapping was undertaken by Western Reefs including costean | ||
mapping and sampling. The Cataract shaft was refurbished and geologically mapped and surveyed. The | ||
Crown Jewel shaft was geological mapped and surveyed also. Windsor Resources in 1988 drilled 174 RC | ||
holes for 11,274m. Newmont in 1990 drilled 338 RAB holes for 15,446m, 39 RC holes for 4,319m and 4 | ||
diamond holes for 718m. Geological mapping and soil sampling was also undertaken. Mt Monger Gold | ||
Project in 1993 drilled 116 RC holes for 6,222m. Fimiston Mining NL in 1995 drilled 110 RC holes for | ||
7,257m and 1 diamond hole for 195m. The data relating to the Boorara gold deposits comprising the | ||
Southern Stockwork Zone, Northern Stockwork Zone, Cataract Area, East Lode and Digger Dam was | ||
reviewed. The database was updated to incorporate the drilling completed by Fimiston and cross sections | ||
and interpretations made. A global polygonal based resource estimate was made which estimated | ||
resources of 2.25 million tonnes @ 1.40g/t Au at a cut-off grade of 0.5g/t or 1.42 million tonnes @ 1.72 | ||
g/t Au at a cut off of 1.0 g/t to be estimated. Block modelling of this polygonal data was then completed | ||
which returned a total oxide resource of 1,293,000 tonnes @ 1.49 g/t, and a total fresh resource of | ||
1,095,000 tonnes @ 1.86g/t. New Hampton Goldfields Ltd in 2001 undertook a resource estimate at | ||
Boorara which resulted in a JORC compliant undiluted mineral resource of 1,506,000t @ 1.85 g/t Au. | ||
Open pit design of the Southern Stockwork, Cataract and the Northern Stockwork resulted in a Probable | ||
Reserve of 179,000t @ 3.0 g/t Au. The New Hampton Goldfields Ltd - Jubilee Gold Operations report, | ||
"Mineral Resource Estimate Report, Boorara M26/29 M26/318 and M26/161, June 2001 G Job" outlines | ||
the methodology and an explanation of the resource calculation. Polymetals (WA) Pty Ltd in 2006 | ||
estimated a NON JORC complaint total resource summary of 1,904,800t @1.38g/t Au using a cutoff grade |

of 0.5 g/t Au. Polymetals (WA) Pty Ltd in 2009 completed 18 RC holes for 1770m. From this program 126 | |||
samples with >1.0g/t Au were screen fire assayed, with another 34 duplicates taking the total samples | |||
assayed via screen fire assay to 160. | |||
Deposit type, geological setting and style of mineralisation. | ∙ The Boorara Au deposit is an Archaean mesothermal Au deposit. The Boorara local geology consists of a | ||
sequence of ultramafic, mafic and felsic volcanic and volcaniclastic rocks, with interflow carbonaceous | |||
sediments found on the lithological boundaries. Dolerite intrusions are conformable within the sequence. | |||
The metamorphic grade of rocks at Boorara is lower greenschist facies. The alteration assemblage | |||
associated with better Au grades consists of quartz carbonate and sericite. Pyrite and arsenopyrite are | |||
associated with the better Au grades at Boorara. Mineralisation envelopes at Boorara consist of three | |||
dominant orientations: | |||
1. Regal - NW trending sub-vertical mineralisation which is typically sub parallel to lithology contacts, | |||
with quartz dolerite hosted NW striking and shallow to moderate NW dipping veins and arrays. | |||
2. | Crown Jewel - NW trending, NE shallow dipping mineralisation, sub parallel to lithology contacts | ||
3. | Regal - Quartz dolerite hosted NW striking with shallow to moderate NW dipping vein arrays as seen | ||
in the Boorara trial pit. |
