Montero Mining Finalizes First-Pass Drill Program at Elvira Gold Project in Chile
Montero Mining and Exploration Ltd has finalized its initial first-pass drilling program at the Elvira gold project in Chile, marking an important step in the companyâs effort to test a large mineral system with potential for both epithermal gold and deeper porphyry copper-gold mineralization.
The company said the planned program will include four drill holes totaling about 2,025 metres. These holes are designed to test priority targets identified through a detailed review of geological, geochemical, and geophysical data. The work follows Monteroâs broader interpretation that Elvira may host a preserved high-sulphidation epithermal gold system above or beside a deeper porphyry copper-gold system.
Drilling to Test High-Priority Exploration Targets
The first-pass drill program will focus on areas where several exploration signals overlap. These include alteration patterns, geophysical anomalies, geochemical indicators, and geological structures that may point to mineralized zones.
According to the company, the planned holes will test multiple target types across the Elvira system. One target is located in the central part of a deep chargeability anomaly, which Montero believes could be an important indicator of porphyry copper-gold potential. Another hole will examine a broad copper-bearing trend connected to a chargeability signature that extends from shallow to deeper levels.
Additional drilling will test a vertically extensive resistivity anomaly interpreted as a possible silicified feeder zone. The company also plans to investigate a discrete resistive body linked to high-sulphidation alteration beneath the southern epithermal gold target area.
CEO Highlights Improved Understanding of Elvira
Montero CEO Dr Tony Harwood said the companyâs recent technical work has significantly improved its understanding of the Elvira project. He noted that the drill program is designed to test the strongest targets within Monteroâs interpreted epithermal-to-porphyry exploration model.
This model is important because epithermal systems can host gold near the surface, while porphyry systems can contain larger copper-gold mineralization at depth. By testing both styles, Montero aims to better understand the scale and potential value of the project.
Historical Drilling Supports Exploration Interest
Historical public-domain information from BuenaVista Gold Ltd. in 2015 reported that 5,711 metres of drilling had previously been completed at Elvira across two campaigns. Reported intervals included 39 metres grading 0.66 grams per tonne gold, 114 metres grading 0.14% copper, and 128 metres grading 0.23% zinc.
BuenaVista also noted that widespread base-metal and silver zoning could suggest a mineralized halo around a concealed target. This historical context supports Monteroâs view that Elvira may contain a broader mineral system that has not yet been fully tested.
Technical Approach and On-Site Analysis
Montero plans to begin drilling using the larger HQ core size to improve sample quality. However, the company may switch to the smaller NQ core size if drilling depth or ground conditions require it.
The company will also use portable XRF analysis on site. This tool can provide rapid, indicative geochemical data during drilling. While not a replacement for certified laboratory assays, it can help exploration teams make faster decisions by identifying metal associations and alteration trends in real time.
Market Reaction
Following the announcement, Montero shares gained around 1.7% in Toronto on Tuesday morning, according to Proactive. The movement reflected investor interest in the companyâs next phase of exploration at Elvira.
Why the Elvira Project Matters
The Elvira gold project is located in Chile, a country known for its strong mining industry and significant copper and gold resources. For junior exploration companies like Montero, defining a meaningful mineral system can be a key step toward building project value.
The upcoming drill program is still early-stage, and results will be needed before the company can confirm the strength, size, or grade of any mineralized zones. However, the combination of historical drilling, modern reinterpretation, and multiple geophysical and geochemical targets gives Montero a clearer path for testing the project.
