Heliostar Drills 46.0m Grading 13.4 g/t Gold Within 129.2m Grading 6.0 g/t Gold at Ana Paula, Mexico
- Significant high-grade gold mineralization in hole AP-23-293 with a 139% increase in grade, potentially improving the resource model
- Positive drill results reinforce the view of Ana Paula's potential as a high-margin, underground gold mine
- Continuity of gold mineralization in the High Grade Panel with only three out of forty-nine samples returning less than 2 g/t gold
- Unexpectedly lower intercepts in holes AP-23-295 and AP-23-296 compared to the model at a >5 g/t cut-off grade
Highlights:
- Hole AP-23-293
- 129.2 metres @ 6.0 grams per tonne (g/t) gold including;
- 46.0 metres @ 13.4 g/t gold including;
- 28.5 metres @ 17.4 g/t gold
- Hole AP-23-294 (drilled above the High Grade Panel)
- 13.95 metres @ 6.4 g/t gold;
- The results from AP-23-293 are the most significant reported in Heliostar's reassessment of the High Grade Panel. They infill a gap in the resource to connect a now continuous 195-metre-long strike length of drill hits with more than 15 grams per tonne of gold.
Vancouver, British Columbia--(Newsfile Corp. - June 12, 2023) - Heliostar Metals Ltd. (TSXV: HSTR) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") is pleased to report additional drill results from the Ana Paula project in Mexico. These four holes continue to assess mineralization within and above the High-Grade Panel at the core of Ana Paula. This is the area of the deposit that Heliostar believes has the potential to increase grade significantly. This drill program will evaluate Ana Paula's ability to host a high-margin, underground gold mine development opportunity.
Heliostar CEO, Charles Funk, commented, "The key to our vision for Ana Paula's future is to define high-grade, underground-minable gold mineralization. The current drill program's exceptional intercepts reinforce this view. The results from hole AP-23-293 illustrate the potential with a
Ana Paula is an advanced gold project with over US
The Company believes this program will deliver a technically simpler project with better economics and a materially improved Net Present Value (NPV) for Ana Paula.

Drill hole AP-23-293 targeted one of the largest data gaps near the center of the High-Grade Panel. The goal of AP-23-293 was to test the continuity of high-grade gold mineralization across this gap.
Assay results for AP-23-293 show 46 metres at 13.4 g/t gold, within 129.2 metres at 6.0 g/t gold. These grades and widths represent a
Continuity of gold mineralization remains a feature of the High Grade Panel with only three of forty-nine samples that make up the 46 metres at 13.4 g/t gold in AP-23-293 returning less than 2 g/t gold.

Drill holes AP-23-294, 295, and 296 are lower priority holes completed whilst awaiting drill pads to be prepared for the up-plunge target.
Hole AP-23-294 returned an unexpectedly better intercept of 13.95 metres at 6.4 g/t gold within 67.2 metres at 2.1 g/t gold. These results came from an area where the model only indicated grades below 5 g/t gold.
Hole AP-23-295 contained 5.5 metres at 4.9 g/t gold within 41.5 metres at 2.6 g/t gold. AP-23-296 returned 2.0 metres grading 13.6 g/t gold. These results were respectively
The three holes competed above the panel extended potentially mineable underground grades over a vertical range of 170 metres. They show that mineralization extends more shallowly than modelled and in more discrete narrow zones than within the High-Grade Panel. They are expected to add underground mineable ounces in the 2023 resource update.
Drilling Progress
Currently eleven holes have been completed at Ana Paula in the current program. Heliostar has reported results from six holes to date. The next drill hole, AP-23-297, tests the up-plunge extension of mineralization and then continues deeper into the target. Ultimately, it will assess the internal continuity of the High-Grade Panel. It will also contribute a large amount of sample material for the metallurgical program. Holes AP-23-298 to AP-23-301 all test zones in the up-plunge target.
