Adam Lundin, CEO comments, "This year has been transformational for Josemaria with significant advancement in all major key aspects of the project. We are in a fortunate position to have one of the largest and most advanced copper projects in the world, located in the San Juan Province of Argentina. The Company continues to be encouraged by the level of support shown at the federal, provincial, and local levels in Argentina to work collaboratively to move this Project forward. Active engagement continues with all levels of government, including discussions aimed at finalizing and securing commercial and fiscal terms applicable to the Project and Environmental Social Impact Assessment ("ESIA") approval. Josemaria remains one of the largest undeveloped copper-gold projects in the world, with a proven and probable reserve profile not found in any other junior mining company: 6.7 billion pounds of copper, 7.0 million ounces of gold, 31 million ounces of silver." (See Table 1 below for details).

Operations Update

The Company continues to aggressively advance all critical areas of the Josemaria Project including:

• Project Engineering: Engineering to date has made significant advancements to de-risk and optimize the process flowsheet with improvements in the crush/convey, grinding, flotation and tailings. An area of significant progress is the grinding circuit reducing the size of the SAG mills from 42 foot diameter to 40 foot mills achieved through the implementation of 2-stage pebble crushing while maintaining the 150 ktpd design throughput. The illustration below shows the revised plant layout as of August 2021. The Project is proceeding to Basic Engineering with the goal of completion during the second quarter of 2022;
  
  
• Development, Infill and Exploration Drilling: planning to execute a 65,000-metre drill program aimed primarily at providing development/infill geo-metallurgical data and acquiring additional site geotechnical information for key Project infrastructure and pit configuration. Life of mine hydrogeology and aquifer modelling will be updated with additional water well and piezometer drilling. It is anticipated that up to 8 rigs will be active at the peak of the drilling program. Management has a high degree of confidence drilling will lead to mine life expansion and a significant portion of inferred material moving into reserves. At site, camp expansion activities are ahead of schedule, and drilling is expected to commence in November. Regional Exploration program plans are being finalized to test targets outside the current resource but adjacent to the Project;
  
  
• ESIA Approval Process: following the submission of the ESIA in February 2021, we continue our engagement with the San Juan authorities in their evaluation process. We anticipate the ESIA evaluation process to be completed in 1H 2022; and
  
  
• Offsite infrastructure: including access road and electrical power, and logistics studies are ongoing, aimed at finalizing plans for integration into the design of the Project during Basic Engineering.

Financing Update

The Company is pleased to announce that it has entered into two credit facilities totaling US$20 million (collectively the "Facilities"), one with Lorito Holdings S.à.r.l. ("Lorito") for US$10 million (the "Lorito Facility") and one with Zebra Holdings and Investments S.à.r.l. ("Zebra") for US$10 million (the "Zebra Facility"). Lorito and Zebra, who report their security holdings as joint actors, are insiders of the company and are private corporations controlled by a trust settled by the late Adolf H. Lundin. Proceeds from the Facilities will be used to provide additional financial flexibility to fund the Company's ongoing work programs and provide general working capital. The Facilities provide an additional source of funds on top of the $US19.4 million currently available to be drawn under existing outstanding credit facilities provided by Lorito and Zebra.

Commenting on the new credit facilities, CEO Adam Lundin stated, "We appreciate the continued financial support of our largest shareholders who remain committed to advancing the Josemaria Project towards construction. The new credit facilities will allow us to continue advancing all aspects of the Project, while working closely with the Government to finalize commercial terms."

Each of the Lorito Facility and the Zebra Facility will be evidenced by a debenture (collectively the "Debentures") each of which will be unsecured and will have a term of 18 months ending March 7, 2023 (the "Maturity Date"). No interest is payable during the term of the Debentures, however, any amount of the Lorito Facility or the Zebra Facility remaining unpaid and outstanding on or after the Maturity Date shall bear interest at a rate of 5.00% per annum until repaid in full.

Subject to approval of the Toronto Stock Exchange (the "TSX"), the terms of the Facilities include the Company issuing 25,000 common shares to each of Lorito and Zebra for an aggregate of 50,000 common shares of Josemaria (the "Common Shares") and an additional 450 Common Shares per month for each US$50,000 of the Lorito Facility or the Zebra Facility outstanding from time to time up to the Maturity Date. All securities issued in conjunction with the Facilities will be subject to a four-month hold period under applicable securities law.

The Common Shares to be issued pursuant to the terms of the Debentures will be issued at a deemed price of $1.06 per share, being the closing price of the Common Shares on the TSX on September 7, 2021.

Subject to the approval of the TSX, the Company has also entered into agreements with Lorito and Zebra (the "Agreements") to extend the maturity dates of the $US27 million of debentures currently outstanding (US$7.6 million drawn) from November 25, 2021, to March 7, 2023 to align the maturity date on all debentures. No other terms of the existing debentures have been amended.
