On May 28, 2026, Algo Grande Copper Corp. (ALGR:TSX.V) announced the completion and interpretation of magnetic and Lidar surveys along the Adelita project's 6-kilometer-long granodiorite-limestone corridor Sonora, Mexico. The data has been used to finalize drill targeting for Algo Grande's planned Phase 2 diamond drilling program that will start in June 2026.

Major Drilling Group International Inc. (MDI:TSX) will execute the drill campaign beginning June 5, 2026, and will be the company's largest drill campaign at Adelita to date, doubling the historical drilling on the property. The goal of the campaign is to expand the high-grade Cerro Grande skarn discovery while testing other targets across the broader mineral system.

CEO of Algo Grande, Enrico Gay, said in the release: "I could not be prouder of our team - the Phase II drill program marks a major step as it will effectively double historical drilling completed on the Adelita project to date. The new drone magnetic survey has defined a 2.5-kilometer target corridor surrounding the Cerro Grande discovery, giving us a clear pathway to potentially grow the footprint significantly. At the same time, maiden drill programs at Las Trancas and Cerro Potrero provide exposure to entirely new discovery opportunities across the broader Adelita district."

The press release defined the three objectives of this Phase 2 program as:

• Expanding the Cerro Grande Skarn: "Recent drilling at Cerro Grande confirmed a large, high-grade multi-horizon skarn system, including assay results of 36.00 metres grading above 1.0% Cu (copper) and 14.79 meters grading 1.4% Cu within a broader mineralized interval."
• Cerro Portrero South Maiden Diamond Drilling Program: "Recent surface work identified copper-gold-silver skarn mineralization exposed over approximately 300 metres of strike length, coincident with a strong magnetic anomaly defined by the new survey data. A total of 14 rock samples identified copper mineralization, including three samples grading above 1% Cu, four samples above 1 g/t Au (gold), with peak values of 3.06% Cu, 3.72 g/t Au, and 232 g/t Ag (silver)."
• Las Trancas Epithermal System Maiden Diamond Drill Program: "Recent sampling at Las Trancas returned exceptionally high-grade silver, copper, and gold values from surface mineralization and historical workings. Notably, three of four collected samples returned grades above 1% Cu, including peak values of 41.4% Cu, 2.0 g/t Au, and 1,570 g/t Ag from a selective stockpile sample."

Upcoming drilling will test and expand mineralization in all three areas.

Algo Grande Copper Corp. is a Canadian exploration company focused on testing overlooked, potentially high-value properties in North America, with current projects centered in Mexico. The company partners with Megaw Exploration Associates (MXA) for operational support.

Copper Resilient Through Uncertainty

Copper, a necessary industrial metal, even hit a low at US$6.37 per pound on May 29.

On Friday, May 29, 2026, President Trump said a ceasefire deal between the U.S. and Iran could be possible, should Iran agree to never create a nuclear weapon. Other requirements on the U.S. side include an immediate reopening of the Strait of Hormuz and removal of all mines located within the strait. A May 29 article by Investing.com discussed how these tensions are affecting the metals markets, saying, "In the current environment, investors are increasingly worried that higher oil and energy costs linked to the Middle East crisis could fuel broader inflation pressures, forcing the Federal Reserve to maintain restrictive monetary policy." Often immune to stock fluctuations due to its critical usage needs, renewed suspicion of U.S. tariffs on China's copper exports have also caused the rates to drop

Copper is considered a safe-haven asset and is often regarded as a sensible investment during times of global uncertainty, as The Economic Times said on May 28, 2026, writing: "The precious metals markets remain highly sensitive to interest rates, inflation expectations, and geopolitical developments."

Analysts Buy into Algo Grande

Robert Sinn of Goldfinger Capital called Algo Grande a 'new favorite' in a contributed opinion article for Streetwise Reports on April 2, 2026, saying he looked forward to an expected aggressive news cycle from the company over the next several months. Sinn stated he had used the recent market correction to initiate a position in Algo Grande's shares.

¹Even before the company's announcement on Phase 1 results, Technical Analyst Stewart Thomson shared his opinion on Algo Grande in a February 17, 2026, contributed opinion for Streetwise Reports.

Thomson called the company's limited number of shares outstanding and percentage of insiders and strategic investors in the stock 'impressive', giving a "Speculative Buy" rating. He projected Algo Grande's stock to have a short-term technical price target of CA$1.00 and a long-term technical price target of CA$6.00.

2026 Stacked with Catalysts

Algo Grande's investor presentation outlines its plans for the next year, with advancing its secondary targets of Las Tabias, Las Trancas, and Mezquital via mapping and sampling intended to begin in Q2 2026. These plans will occur in conjunction with licensing a wide Lidar Survey and a Drone Magnetic Survey. 

In Q3 and Q4, the company intends to initiate Phase 2 on the Cerro Grande site via a 10,000-meter drill program targeting skarn zones with the highest potential and completing metallurgical sampling in the same area. At the same time, Algo Grande plans to use this year's fieldwork findings to finalize porphyry and secondary target definitions at Metzquital and Las Trancas.
