Heliostar Metals was the only company to publish results from drilling campaigns in Mexico during the week.

The company released results from the current drill program at Ana Paula, in Guerrero, program that aims to convert inferred resources to higher confidence classifications and support the ongoing feasibility study (FS) and test the next exploration targets around the deposit. Heliostar has completed 44 holes and 12,615 m to date “along north-south sections with angled holes to better define the overall east-west orientation of the High Grade Panel.”

Ana Paula is a complex deposit within the Guerrero Gold Belt in southern Mexico. Igneous rocks intruding a mesozoic sedimentary package produced skarn alteration, breccias and replacement mineralization, with even a late epithermal phase present.

The next paragraph is from the 2023 technical report: 

In general, four gold depositional settings are recognized at Ana Paula, including:

1. Quartz-sulphide and quartz-carbonate-sulphide veinlets, stockworks with sulphide clots and disseminations in both intrusions and hornfels.

2. Narrow semi-massive sulphide contact replacement of limestone or hornfels/skarn at the intrusion contacts.

3. 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).

4. 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 the Complex Breccia domain.
