GR Silver Mining Launches Major Step-Out Drill Program at Plomosas

GR Silver Mining ( (TSE:GRSL) ) has provided an announcement.

GR Silver Mining has launched a 20,000-metre step-out drilling campaign at the San Marcial Area of its Plomosas Silver Project, deploying multiple rigs under a five-year surface drilling permit to expand known silver mineralization along strike and at depth. The program, which doubles drilling outside the current resource area and includes testing a newly discovered parallel breccia zone, is expected to underpin an updated mineral resource estimate and a preliminary economic assessment in late 2026, while an operational shift to Durango addresses security challenges in Sinaloa and supports safer, more efficient field activities.

The drilling objectives include extending the silver-mineralized hydrothermal breccia by 200 metres along strike, defining mineralization down to 400 metres depth, and adding high-grade silver ounces in zones already indicated by wide, high-grade intersections from the 2025 campaign. By integrating new geological modelling and recent discoveries, the initiative is positioned to materially grow the project’s resource base and de-risk future development, with implications for the company’s growth trajectory and attractiveness to investors in the silver space.

The most recent analyst rating on (TSE:GRSL) stock is a Hold with a C$0.63 price target. To see the full list of analyst forecasts on GR Silver Mining stock, see the TSE:GRSL Stock Forecast page.

Spark’s Take on TSE:GRSL Stock

According to Spark, TipRanks’ AI Analyst, TSE:GRSL is a Neutral.

The score is held back primarily by weak financial performance (pre-revenue operations with ongoing losses and negative free cash flow), partially offset by a strong technical uptrend and positive momentum. Valuation is middling because the negative P/E reflects unprofitable operations and there is no dividend yield support.
