- Ana Paula drill program to be extended to 20,000 metres of drilling
Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) is pleased to announce additional results from the current drill program at its 100% owned Ana Paula project in Guerrero, Mexico. The program aims to convert inferred ounces to higher confidence classifications. It will also support the ongoing Feasibility Study and testing the next exploration targets around the Ana Paula deposit.
Heliostar CEO, Charles Funk, commented, ‘It’s rare to find a deposit that consistently produces 50-100m wide drill intercepts of these gold grades. Ana Paula is wide, high-grade, and shallow, with good underground mining conditions. These factors drive the low $1,011 all in sustaining cost in our new PEA for the project. It will also drive high margins at the project. The current program is focused on upgrading inferred ounces to higher confidence categories and the new data will be incorporated into a Feasibility Study. The lower costs drive a lower cut-off grade in the planned mine that opens the potential for more inferred material conversion. To maximize this opportunity, we will expand the program by 33% to 20,000 metres to allow for more infill and exploration drilling at Ana Paula. Across the Company, we have another study, a Prefeasibility Study for Cerro del Gallo, planned this quarter. We are also drilling at San Agustin and La Colorada. These programs should increase production and unlock the value we see in our deep growth portfolio.’
Drilling Program
Heliostar has completed 44 holes and 12,615 metres drilled to date. Drilling is designed along north-south sections with angled holes to better define the overall east-west orientation of the High Grade Panel. Heliostar’s drilling approach at Ana Paula has been to change the direction of drilling by approximately 90 degrees from the majority of historic intercepts. The Company believes that this change contributed to demonstrating more continuous and higher-grade gold mineralization within the High Grade Panel than recognized by previous operators.
Where appropriate, the holes are also being used to collect rock strength data, hydrogeologic data and samples for further metallurgical studies that will directly influence the Ana Paula mine design in the ongoing Feasibility Study.
Drill Results Summary
Holes AP-25-331, AP-25-333, AP-25-334 and AP-25-336 are resource conversion holes drilled in the central part of the High Grade Panel. Holes AP-25-334 and AP-25-336 were drilled on the same fence, with AP-25-334 targeting the polymictic breccia and hanging wall mineralization, and AP-25-336 targeting the polymictic breccia and footwall mineralization. Hole AP-25-334 intercepted a wide zone of 92.05 metres (‘m’) grading 4.33 grams per tonne (‘g/t’) gold, whilst AP-25-336 returned intervals of 3.2 m at 15.58 g/t gold, 65.15 m at 5.39 g/t and 43.55 m at 4.66 g/t gold with a 3.05 m interval with 24.64 g/t gold.

Hole AP-25-333 is located 60 m to the east of the above-mentioned fence and returned two high-grade intervals of 26.6 m grading 4.78 g/t gold and 83.2 m grading 17.35 g/t gold. Hole AP-25-331 is a step out 32 m to the southeast and returned a 7.95 m zone grading 7.92 g/t gold and a wide high-grade interval of 70.65 m at 9.38 g/t gold.
Holes AP-25-330, AP-25-332 and AP-25-335A are geotechnical holes for mine development planning and returned assay results in line with expectations, including intervals of 48.5 m of 5.48 g/t gold, 5.2 m of 4.23 g/t gold and 35.55 m of 6.73 g/t gold, respectively.
True widths are unknown. Mineralization at Ana Paula occurs as disseminations or vein stockworks with variable controls including rock porosity, lithology and fault networks.
Drilling continues throughout the High Grade Panel and its less well-defined east and west edges, with assays pending from twelve holes. Two of the drills have begun to target deeper inferred mineralization and the northern exploration zone, which is approximately 250 m north of the High Grade Panel that has two drill holes pending assay.
The next Ana Paula drill results are anticipated to be released in December.
