- One World Lithium Inc., announced sampling results at its Salar del Diablo Lithium project in Baja California Norte. 59 auger samples and 4 rock-chips samples were collected returning Li values ranging from a low of 4.7 to a high of 196.5 ppm, with an average of 84 ppm Li.
- SilverCrest Metals Inc., reported drill results on the Babicanora Vein, including Area 51, within its Las Chispas project in Sonora. Significant results are 4m of 22.8 g/t Au and 1,718 g/t Ag, and 4.5m of 8 g/t Au and 912 g/t Ag. To date, a total of 20 holes have intersected the high-grade footprint of the Area 51 zone, with an average grade of 10.4 g/t Au and 944 g/t Ag.
- Silver One Resource Inc., identified four new geophysical exploration targets at its Peñasco Quemado project in Sonora. The CSAMT identified deep zones of low resistivity suggesting channels for potential mineralizing solutions. These 4 targets expand the exploration potential, and are encompassed by strong to moderate Zn, Pb, Cu, and Ag anomalies.
- Azure Minerals Limited, announced metallurgy results on its Oposura project in Sonora, with > 85% Zn and > 80% Pb recoveries. Further testwork will be carried out to optimize recovery and concentrate grades.
- Mammoth Resources Corp., announced results from 2 holes on its Tenoriba project in Chihuahua. The diamond hole drilled at Masuparia area intersected 45.4m of 0.53 g/t Au and the first hole ever drilled at Los Carneritos area intersected 39m of 0.21 g/t Au.
- Kootenay Silver Inc., announced drill results, 1km away from the current resources at its La Cigarra project in Chihuahua. Significant intersections are 17m of 267 g/t Ag, including 10m of 437 g/t Ag, and 16m of 112 g/t Ag, including 10m of 144 g/t Ag. The results indicate the mineralized structure extends for an additional 1Km of strike to the northwest of the resource area.
- Advance Gold Corp., announced underground sampling results on its Tabasquena Mine in Zacatecas. The sampling returned grades of up to 362 g/t Ag near surface and two of the deepest samples returned 642 g/t Ag and 656 g/t Ag.
