Heliostar Metals was the only company to release drilling results from projects in Mexico during the week, but the announced intercepts of definition drilling at Ana Paula, in Guerrero, are striking. The results from two holes present several intersections that run up to 716 gpt*m Au in the High Grade Panel zone of the Ana Paula deposit.
In its web Heliostar states: “In general, there are four gold depositional settings at Ana Paula, including:
- Quartz-sulphide and quartz-carbonate-sulphide veinlets, stockworks with sulphide clots and disseminations in both intrusions and hornfels.
- Narrow semi-massive sulphide contact replacement of limestone or hornfels/skarn at the intrusion contacts.
- Sulphide clots, rims, and masses in narrow contact replacement of breccia hosted in intrusions at or near the sedimentary contacts and/or fault contacts (detachment faults).
- Associated with a sulphide constituent within breccia matrix and with sulphide replacement textures within structurally controlled breccia formed oblique to the dominant northerly trending westerly dipping stratigraphy.”
“The bulk of the high-grade mineralization at Ana Paula occurs in a Complex Breccia domain. This lithological unit consists of a polymictic breccia in a steeply south plunging column. An alteration-mineralization halo surrounds the Complex Breccia, bearing gold mineralization characterized by veins, fracture zones, and massive sulphide contact replacements.”
