Vancouver, British Columbia--(Newsfile Corp. - September 11, 2024) - Copper Standard Resources Inc. (CSE: CSR) ("Copper Standard") and Pucara Gold Ltd. (TSXV: TORO) (BVL: TORO) ("Pucara") are pleased to announce that they have entered into an arrangement agreement on September 10, 2024 (the "Arrangement Agreement"), pursuant to which Copper Standard will acquire all of the issued and outstanding common shares of Pucara (the "Pucara Shares"), in exchange for common shares of Copper Standard (the "Copper Standard Shares"), by way of a plan of arrangement (the "Transaction"). The Transaction will create a combined company that consolidates a prospective copper exploration portfolio totaling over 17,000 hectares in Peru. Further details of the Transaction are outlined below.

Transaction Highlights:

• Deliver increased scale and enhanced diversification with the addition of three prospective copper exploration assets located in Peru, two of which were selected to be optioned by the late David Lowell, to Copper Standard's portfolio.

• Provide synergy and cost savings with Copper Standard's board and management team with a proven history and in-country track record of discovery, exploration success, mine building, operations, community engagement and monetization leading the combined company.

Pucara Copper Projects:

Pacaska is an epithermal high-sulfidation gold/porphyry copper target that sits on 7,650 hectares of land with a widespread mineralized footprint. The geology of Pacaska is analogous to various world-class deposits, such as the Pierina Mine in Peru. Rock sampling at Pacaska has returned 17 g/t gold and 11% copper. In 2019, an extensive shallow surface 300 line-km magnetometry and IP geophysical program was completed.

Paco Orco is a carbonate replacement type target with distal mineralization. The 4,400-hectare claim block is largely under-explored containing mineralized gossan and jasperoid silica outcrops that extend for at least two kilometres. Surface rock samples from the project have included up to 0.58% lead, 0.26% zinc, and 58 g/t silver. A third party has an earn-in option agreement on Paco Orco for up to 75% interest. The third party has agreed to obtain all necessary drill permits and spend US$4 million during the first three years for 51% interest. An additional 24% interest, for a total of 75%, can be earned after third party spends US$11.5 million over four years, fully funding a Pre-Feasibility Study ("PFS") for the project, and pay US$0.5 million.

Capricho is a 3,768-hectare concession package with a porphyry copper target. Recent prospecting work on the claims has uncovered porphyry mineralization in stockworks and altered intrusive rocks. The concessions contain enrichment zones of up to 3% copper. A third party has an option to earn a 75% interest over three stages. The third party must obtain all necessary agreements and permits for drilling and spend US$5 million during the first three years for a 51% interest. The remaining 24% interest will be granted when the third party spends US$11.5 million over the next four years, solely funding a PFS on the project, and pay US$0.5 million.

Matt Fargey, CEO of Copper Standard, commented: "This Transaction is an exciting opportunity to unite complementary assets, teams, and investors to create value for all Copper Standard and Pucara shareholders. The late David Lowell endorsed each of Copper Standard and Pucara's copper exploration projects and now combining them all together will allow Copper Standard to leverage its Peruvian team to advance the exploration efforts in-country."

Greg Davis, CEO, President, and Director of Pucara commented: "We are very pleased to be entering this combination with Copper Standard. By combining with Copper Standard, Pucara's shareholders will benefit from the synergies and cost savings of leveraging the combined company's in-country management team while also providing a refreshed approach to community relations at the Pacaska project for obtaining required permits to commence a drilling program."

Transaction Terms

Pursuant to the terms and conditions of the Arrangement Agreement, the holders of the issued and outstanding Pucara Shares will receive 0.1 Copper Standard Shares for each one (1) Pucara Share held (the "Exchange Ratio"). Pucara stock options and warrants that are outstanding at the time of completion of the Transaction will become exercisable for Copper Standard Shares on substantially the same terms and conditions, with the number of Copper Standard Shares issuable on exercise and the exercise price adjusted in accordance with the Exchange Ratio. The Transaction will be carried out by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia).

The Exchange Ratio implies a price of $0.05 per Pucara Share and a premium of approximately 67% based on the closing prices of Copper Standard and Pucara on September 10, 2024, and a premium of approximately 50% based on the 20-day volume weighted average prices of Copper Standard Shares and Pucara Shares as of September 10, 2024. Upon completion of the Transaction, existing Copper Standard and Pucara shareholders would own approximately 85% and 15% of the combined company, respectfully, on an undiluted basis.

Upon completion of the Transaction, Copper Standard will continue to be listed on the Canadian Securities Exchange under the same Copper Standard name and ticker symbol. The Arrangement Agreement contains customary deal-protection provisions including a non-solicitation covenant on the part of Pucara and a right for Copper Standard to match any Superior Proposal (as defined in the Arrangement Agreement). Under certain circumstances, Copper Standard would be entitled to a termination fee or expense reimbursement fees of $0.25 million.

Complete details of the Transaction will be included in a management information circular to be delivered to Pucara security holders in the coming weeks.

Conditions to Completion

The completion of the Transaction is subject to a number of terms and conditions, including without limitation the following: (a) approval of the Pucara shareholders, as described below; (b) acceptance of the TSX Venture Exchange ("TSXV"); (c) approval of the British Columbia Supreme Court; (d) there being no material adverse changes in respect of either Copper Standard or Pucara; and other standard conditions of closing for a transaction of this nature. There can be no assurance that all of the necessary approvals will be obtained or that all conditions of closing will be satisfied.

The Transaction is subject to the approval at a special meeting of Pucara shareholders by (i) 66 2/3% of the votes cast by Pucara shareholders, and (ii) if required, a simple majority of the votes cast by the Pucara shareholders, excluding the votes cast by certain persons as required by Multilateral Instrument 61-101 - Protection of Minority Securityholders in Special Transactions. Copper Standard and Pucara are arm's length parties and, accordingly, the Transaction is not expected to a related party transaction. No finder's fees are being paid in connection with the Transaction.

Officers and directors along with certain shareholders of Pucara who collectively control 40.05% of the Pucara Shares (excluding those issued in connection with the Pucara financing discussed below) on an undiluted basis have entered into voting and support agreements pursuant to which they have agreed to vote their shares in favor of the Transaction.

Board of Directors and Management

Upon closing of the Transaction, the board of directors of Copper Standard will remain unchanged to lead the combined management and project teams. The head office will continue to be in Vancouver, Canada. In addition, on September 10, 2024 and prior to execution of the Arrangement Agreement, Mr. Andy Swarthout resigned as a director of Pucara to avoid conflicts under corporate law as a result of being a director of both Copper Standard and Pucara.

Pucara Financing

Concurrent with signing the Arrangement Agreement, Copper Standard has signed a subscription agreement to subscribe for 8,415,765 units of Pucara (the "Units") at a price of $0.03 per Unit (the "Pucara Financing"). Each Unit will include one Pucara Share and one half of one common share purchase warrant, with each whole warrant entitling the purchase of one Pucara Share at a price of $0.05 per Pucara Share for a period of five years from the date of issuance. The Pucara Financing is expected to close within five days of this announcement.

The Pucara Financing will be relying upon exceptions permitted by the TSXV in order to issue the Pucara Shares at less than $0.05 per Pucara Share. Pucara also intends to rely on the "part and parcel exception" under the policies of the TSXV in respect of the Pucara Financing as the Pucara Financing is integral to the Transaction by capitalizing the combined company.

It is anticipated that proceeds from the Pucara Financing will be utilized for the payment of legal and other advisor fees in connection with the Transaction (approximately 50% of the gross proceeds) and for other general working capital purposes (approximately 50% of the gross proceeds), provided that permitted working capital purposes shall not include payment of bonuses, amounts in respect of a change of control, nor any other amounts to employees, consultants or related parties. None of the proceeds raised will be used to pay "Non-Arm's Length Parties" or to fund "Investor Relations Activities" (as each is defined in the policies of the TSXV).

Transaction Timeline

Pursuant to the Arrangement Agreement and subject to satisfying all necessary conditions and receipt of all required approvals, the parties anticipate completion of the Transaction by the end of 2024. Following completion of the Transaction, Pucara Shares will be de-listed from the TSXV and Lima Stock Exchange and Pucara will cease to be a reporting issuer under Canadian securities laws.
