Here's a summary of the NE Riqueza drilling to date. I make hole 8 (27) nearly at target depth and it will be interesting to see whether it is drilled deeper given the proposition illustrated in the IP chargeability profile:
Also, here are maps of the magnetics from the Riqueza AMAGRAD survey overlaid with drill hole locations and the chargeability and conductivity anomaly zones from the Induced Polarisation survey:
Sierra Metals reports success identifying mineralisation at Yauricocha (NNW of Riqueza at the top of the Chonta Fault zone) with conductivity and chargeability anomalies in the same Jumasha limestone as at NE Riqueza.
Magnetic surveys "outlined the Antamina Cu-Zn skarn deposits with the magmatic skarn intrusions associated with magnetic highs", also in Jumasha limestone.
"Geophysical interpretations are inherently nonunique, and geology is always complicated" but I'm certainly looking forward to results from hole 8 (27) and eventually hole 9.
