Delineates a Large Copper Resource Next to Capstone Copper

• GRG has completed a maiden resource estimate on its flagship San Pietro copper-gold-iron-cobalt project in Chile, the largest copper-producing nation in the world.
• San Pietro is located in between three copper projects operated by Capstone Copper (TSX: CS/MCAP: $6.4B), including an operating open-pit mine.
• The company has delineated a substantial inferred resource totaling 4.4 Blbs  of CuEq at 0.41%. We believe San Pietro has significant resource expansion potential, with mineralization open in multiple directions, and 50% of the project area remaining untested.
• GRG is planning a phase three drill program in Q3-2025 to explore multiple underexplored targets, and perform infill drilling within the resource area, aiming to potentially identify higher-grade zones, and upgrade the current resource estimate to the measured and indicated categories.

• With copper trading near record highs, we anticipate an increase in M&A activity over the next 12 months, as larger companies target juniors to expand their portfolios. We remain bullish on near-term prices due to escalating geopolitical and trade war risks.
• Upcoming catalysts include phase three drilling, and ongoing and planned exploration by GRG and its partners on non-core assets.
• GRG is trading at $0.005/lb of CuEq vs the comparables average of $0.02/lb, a 71% discount.

San Pietro IOCG Project (Chile): Maiden Resource Estimate

A copper-gold-iron-cobalt project in a prolific mining district in Chile, hosting multiple major iron-copper-gold deposits. Situated between three copper projects operated by Capstone Copper, including an operating open-pit mine

San Pietro’s tonnage and copper-gold grades are comparable to those of neighboring projects. Potentially open-pittable resources totaling 4.4 Blbs CuEq, representing significant tonnage, at a relatively low grade

The maiden resource estimate was based on 83 holes/32,733 m. Resources are spead across two deposits: Rincones and Colla

We believe there is significant resource expansion potential as both Rincones and Colla remain open in multiple directions. In addition, the current estimate does not include five drill-ready targets (Mariposa, Rodeo, Radiss Norte, Noemi, and Lolita Norte), and 50% of the project area remains untested

The company is planning a phase three drill program in Q3-2025 to explore multiple underexplored targets, and perform infill drilling within the resource area, aiming to potentially identify higher-grade zones, and upgrade the current resource estimate to measured and indicated categories.

Financials

Subsequent to Q3-2024, GRG closed a $0.78M equity financing

GRG is planning a $20M equity raise to fund its upcoming drill programs 

FRC Valuation and Rating

As a result of the maiden resource, we are introducing our fair value estimate in this report. GRG is one of the most undervalued juniors on our list of comparables

GRG is trading at just $0.005/lb vs the sector average of $0.02/lb. Applying the sector average EV/lb of $0.016 to San Pietro’s maiden resource estimate, we arrived at a comparables valuation of $0.21/share 

We are introducing our rating of BUY and fair value estimate of $0.21 share. GRG has significantly boosted the appeal of its San Pietro project with a promising maiden resource estimate. The project's open-pittable design and resource expansion potential are key advantages. Given its current undervaluation relative to peers, and the likelihood of M&A activity in a strong copper market, we anticipate increased market attention on the stock.

Risks

We believe the company is exposed to the following key risks (not exhaustive):

• Metal prices
• Access to capital and share dilution
• Exploration and development 
• No NI 43-101 compliant economic studies
• GRG might not be able to advance all of its projects simultaneously
