Beauce Gold Fields Achieves 88% Drill Success Rate at the Grondin Zone. 3-D Interpretation Confirms 600 M Mineralized Corridor
Executive Summary
- Beauce Gold Fields released a Leapfrog™ 3‑D geological model integrating drill data from the 2023 and 2025 campaigns, visualizing a continuous antiform–saddle reef gold system over a 600 m strike.
- The combined drilling program achieved an 88 % hole‑success rate (14 of 16 holes intersecting ≥0.3 g/t Au), confirming robust mineralization to ~40 m depth and remaining open both laterally and at depth.
- The new model refines targeting for the upcoming winter drill campaign, identifies structural gaps and hinge zones, and will be supplemented with borehole televiewer data to define dip/orientation.
Key Details
- 3‑D Model Highlights
- First three‑dimensional visualization of the antiform–saddle reef system along an 8 km geophysical signature.
- Shows gold‑bearing hydrothermal breccias and quartz crack‑and‑seal veins within folded felsic lapilli tuff.
- Mineralized strike length: ~600 m (from hole GR‑23‑08 to GR‑25‑08).
-
Depth of confirmed mineralization: ~40 m; open at depth and along strike.
-
Drill Program Performance
- Total holes drilled: 16 (8 in 2023, 8 in 2025).
- Holes intersecting gold (≥0.3 ppm): 14 → 88 % success rate, far above the 20‑40 % industry norm for grassroots exploration.
-
Average intercept grades range from 0.2 g/t to 11 g/t Au across multiple intervals.
-
Selected Drill Intercepts (representative examples)
- RG‑23‑01: 1.7 g/t over 3 m; 5.4 g/t over 2.2 m; 8.85 g/t over 1 m; 11.4 g/t over 0.5 m.
- RG‑23‑04: 1.08 g/t over 6 m; 3.6 g/t over 0.5 m.
- RG‑23‑05: 10.88 g/t over 0.5 m; 6.5 g/t over 1 m.
- RG‑25‑02: 5.2 g/t over 0.5 m; 2.8 g/t over 1 m.
-
Additional intervals listed in Table 1 of the release (see original for full table).
-
QA/QC Procedures
-
HQ and NQ core recovery, split‑core sampling, on‑site standards/blanks, assay by MSALABS (Val‑d’Or) using photon assay.
-
Implications for Future Work
- Model identifies “gaps,” hinge positions, and fold repetition patterns to be tested in the upcoming winter campaign.
- Planned borehole televiewer survey to determine precise dip and orientation of gold‑bearing structures, enabling deeper drilling.
