  • Pinnacle goes against gravity at El Potrero

Pinnacle goes against gravity at El Potrero

Drilling up. Drilling along. ‘High-grade’ showing up.

Pinnacle Silver and Gold (TSX-V:PINN) President and CEO Robert Archer joins us after fresh underground drilling at the El Potrero Project in Mexico.

  • Grade: Latest drilling returned up to 58.2 grams per tonne of gold
  • 3D continuity: Adjacent holes are lining up the ‘high-grade’ zone
  • Underground edge: Existing workings let Pinnacle drill from angles surface rigs cannot reach
  • Bigger picture: Mineralised zones are growing beyond what channel sampling first showed
  • Next: More drilling, permitting, and regional work

The vein is getting looked at from every angle.

So far, it keeps giving the same answer.

About the guest and company

Robert Archer is president and CEO of Pinnacle Silver and Gold. The company is advancing the El Potrero Gold-Silver Project in Durango, Mexico, where underground drilling is sharpening the picture around the historical Pinos Cuates mine.

🎥 Watch the full interview to see how Pinnacle is connecting the dots underground.
