Re: Resource Base Limited - Sale of Unmarketable Parcel Facility

Dear Sir / Madam,

Resource Base Limited (ASX:RBX)(Resource Base or the Company) is pleased to advise that it has established an Unmarketable Parcel Sale Facility (Facility) for shareholders who hold less than A$500 worth of fully paid, ordinary shares in the Company (Shares), (Unmarketable Parcel).

Based on the price of Shares at the close of trading on Tuesday, 26 April 2022 (Record Date) of A$0.24, a holding of 2,083 Shares or less constitutes an Unmarketable Parcel.

The Company is offering the Facility to enable shareholders who hold an Unmarketable Parcel to sell their Shares without having to act through a broker or pay brokerage or handling fees. Resource Base will pay all costs associated with the sale and transfer of Shares through the Facility (excluding any tax consequences of the sale, which will be the responsibility of relevant shareholders).

Under the Company's Constitution, Shares must not be sold under the Facility for less than the simple average of the last sale prices of Shares sold on ASX for each of the ten trading days immediately preceding the date of any sale offer the Company receives for the Shares. Each shareholder will receive their proportionate share of the total sale proceeds for all Shares sold through the Facility without any brokerage or handling costs. As participating shareholders will receive an average price for their Shares, the price received may be different from the price appearing in news sources or quoted by ASX on any day and may not be the best price on the day the Shares are sold.

The sale of Unmarketable Parcels through the Facility will also benefit the Company, as it is expected to significantly reduce the administrative costs associated with maintaining a number of small shareholdings on the Company's share register.

In accordance with the Company's Constitution (Constitution) and the ASX Listing Rules, the attached letter and share retention form (Retention Form) will be sent to all shareholders who hold an Unmarketable Parcel on the Record Date.

Shareholders who hold an Unmarketable Parcel and wish to retain their Shares must "opt-out" of the Facility by returning their duly completed Retention Form to the Company's share registry (Computershare Investor Services Pty Limited) in accordance with the instructions on the Retention Form, by no later than 5:00pm (AEST) on Tuesday, 14 June 2022 (Closing Time). Any shareholder who holds an Unmarketable Parcel and does not return a duly completed Retention Form by the Closing Time will have their Shares sold through the Facility.

RESOURCE BASE LIMITED ACN 113 385 425

Resource Base has appointed an independent broker to sell the Shares under the Facility, and the proceeds from the sale of the Shares will be remitted to participating shareholders as soon as practicable following settlement of all Shares sold through the Facility. The key dates in relation to the Facility are set out below:

Event	Date
Record Date for establishing holders of Unmarketable Parcels	26 April 2022
ASX announcement regarding Unmarketable Parcels Sale Facility	27 April 2022
Letter and Retention Form despatched to shareholders holding an Unmarketable Parcel	2 May 2022
Closing Time for receipt of completed Retention Forms	14 June 2022

Resource Base reserves the right to change any of the dates referred to in this announcement or the enclosed letter and Retention Form, or to vary, cancel or delay the Facility or the sale of Shares at any time before Shares are sold, by making an announcement to ASX. The Company has the ability to establish the Facility and facilitate the sale of Unmarketable Parcels under clause 3 of the Constitution and rule 15.13 of the ASX Listing Rules.

The Company does not provide any recommendation or advice as to whether shareholders holding an Unmarketable Parcel should sell or retain their Shares. If you have any questions about the operation of the Facility, please contact the Company on [phone]. This announcement has been authorised for release to ASX by the Company's Board of Directors. If you have any queries in relation to this announcement, please do not hesitate to contact the Company Secretary at the number above.

Yours Sincerely,

Re: Resource Base Limited - Sale of Unmarketable Parcel of Shares

Dear Shareholder,

Resource Base Limited (ASX:RBX)(Resource Base or the Company) is pleased to advise that it has established an Unmarketable Parcel Sale Facility (Facility) for shareholders who hold less than A$500 worth of fully paid, ordinary shares in the Company (Shares), (Unmarketable Parcel).

Based on the price of Shares at the close of trading on Tuesday, 26 April 2022 (Record Date) of A$0.24, a holding of 2,083 Shares or less constitutes an Unmarketable Parcel.

Resource Base appreciates that Unmarketable Parcels can be difficult or expensive to sell, so the Company is offering the Facility to enable shareholders who hold an Unmarketable Parcel to sell their Shares without having to act through a broker or pay brokerage or handling fees. The Company will pay all costs associated with the sale and transfer of Shares through the Facility (excluding any tax consequences of the sale, which will be the responsibility of relevant shareholders).

Under the Company's Constitution, Shares must not be sold under the Facility for less than the simple average of the last sale prices of Shares sold on ASX for each of the ten trading days immediately preceding the date of any sale offer the Company receives for the Shares. Each shareholder will receive their proportionate share of the total sale proceeds for all Shares sold through the Facility without any brokerage or handling costs. As participating shareholders will receive an average price for their Shares, the price received may be different from the price appearing in news sources or quoted by ASX on any day and may not be the best price on the day the Shares are sold.

The sale of Unmarketable Parcels through the Facility will also benefit the Company, as it is expected to significantly reduce the administrative costs associated with maintaining a number of small shareholdings on the Company's share register.

Resource Base has the ability to establish the Facility and facilitate the sale of Unmarketable Parcels under clause 3 of the Company's Constitution (Constitution) and rule 15.13 of the ASX Listing Rules.

WHY AM I RECEIVING THIS LETTER?

Our records indicate that you held an Unmarketable Parcel of Shares based on the price of Shares of A$0.24 as at close of trade on the Record Date. Unless you advise the Company by 5:00pm (AEST) on Tuesday, 14 June 2022 (Closing Time) that you do NOT wish to sell your Shares, the Company intends to sell your Shares through the Facility in accordance with clause 3 of the Constitution and rule 15.13 of the ASX Listing Rules.

To advise the Company that you do NOT wish to sell your Shares, you must complete the share retention form (Retention Form) enclosed with this letter, and return it to the Company's share

RESOURCE BASE LIMITED ACN 113 385 425

registry, Computershare Limited (Computershare), in accordance with the instructions on the Retention Form, prior to the Closing Time.

If, at the Closing Time, the value of your Shares has increased such that you no longer have an Unmarketable Parcel (eg due to an increase in the market price of Shares or the number of Shares you hold), your Shares will NOT be sold.

If you have multiple holdings of Shares which, if aggregated, would not constitute an Unmarketable Parcel, you may contact Computershare at 1300 850 505 (within Australia) or [phone] (outside Australia) to amalgamate your holdings. In these circumstances, your Shares will not be sold.

Please also note that pursuant to clause 3.15 of the Constitution and rule 15.13.5 of the ASX Listing Rules, the Company will not sell your Shares in the event that a third party announces a takeover offer for the Company.

In accordance with its continuous disclosure obligations, the Company may release information to the ASX which may affect your decision as to whether you wish to sell or retain your Shares. If such information is released, it will be published on the ASX website (www.asx.com.au, ASX code: RBX) and on the Company's website (www.resourcebase.com.au).

You should be aware that the fact that your holding of Shares is described in this letter as an "unmarketable parcel" does not mean that you cannot sell your Shares at any time. The use of the term "unmarketable parcel" in this letter is to identify the value of Shares which are eligible for sale through the Facility.

WHAT DO I NEED TO DO?

As a holder of an Unmarketable Parcel as at the Record Date, your options are described below:

1. Sell your Unmarketable Parcel

If you WISH TO SELL your Shares through the Facility, you should TAKE NO ACTION. By refraining from taking any action, you will be deemed to have irrevocably appointed the Company as your agent to:a)sell, or procure the sale of, all of your Shares at a price to be determined, without any costs being incurred by you; and

b) deal with the proceeds of the sale as set out in this letter (for more information about the payment of the sale proceeds through Computershare, please refer to Question 9 of the enclosed Information Sheet).

The Company has appointed a broker to facilitate the sale of the Unmarketable Parcels. Payment for your Shares will be remitted to you as soon as practicable, following settlement of the sale of all Shares sold through the Facility.

2. Retain your Unmarketable Parcel

If you DO NOT WISH TO SELL your Unmarketable Parcel, you MUST OPT-OUT of the Facility by completing and returning the enclosed Retention Form in accordance with the instructions on the Retention Form so that it is received by Computershare prior to the Closing Time.

The key dates in relation to the Facility are set out below:

The Company does not provide any recommendation or advice as to whether shareholders holding an Unmarketable Parcel should sell or retain their Shares.
