Heliostar Drills 33m Grading 16.4 g/t Gold and 9.5m Grading 25.6 g/t Gold, Expands High Grade Panel at Ana Paula
- Hole AP-23-303
- 98.0 metres @ 6.46 grams per tonne (g/t) gold including
- 3.0 metres @ 16.4 g/t gold
- Hole AP-23-304
- 85.5 metres @ 4.73 g/t gold including
- 9.5 metres @ 25.6 g/t gold
- These intercepts expand the High Grade Panel to 280m of total length from near surface
- Respectively, gold grades in holes AP-23-303, AP-23-304 and AP-23-305 are 14%, 3% and 307% higher than that predicted in the current resource model (at a >5g/t cutoff grade)
Vancouver, British Columbia--(Newsfile Corp. - September 6, 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 ("Ana Paula" or the "Ana Paula Project"). These three holes are the first to assess mineralization down-plunge of the High Grade Panel at the core of Ana Paula.
Heliostar CEO, Charles Funk, commented, "The Ana Paula project continues to deliver exceptional results. Drill results are exceeding expectations at every point. The widths of the intercepts, the consistency in the grades, and the improvements in drill intersections over the PFS resource continue to be impressive. As we better define the limits of the High Grade Panel, today from the down-plunge target area, we believe that there is a clearly significant potential for an increase in total ounces and grade in the upcoming resource update."
Heliostar continues to deliver on its three-pronged approach to the re-scoping of Ana Paula in 2023:
- The results announced to date will grow the size of the High Grade Panel in the resource update due in November.
- The grade distribution shows the potential to mine higher gold grades in the early years, and throughout the mine life.
- The metallurgical study results are anticipated to be received by the end of September.
The Company's initial focus has been on the potential to improve the economics of mining the High Grade Panel. Now the Company plans to introduce new exploration targets within and around Ana Paula to start to unlock the full potential of the district.
Results from this press release are from Heliostar's down-plunge growth target at Ana Paula.
Hole AP-23-303 tested a large data gap in the High Grade Panel. The intercept returned significantly higher grades than expected, intersecting 98.0 metres grading 6.46 g/t gold, including 33.0 metres grading 16.4 g/t gold.

Hole AP-23-304 encountered a strong zone of mineralization containing 85.5 metres grading 4.73 g/t gold, including 9.5 metres grading 25.6 g/t gold. This intercept is 15 metres west of the nearest intercept in the High Grade Panel and will locally add a significant amount of high grade gold in an updated resource estimate.
Hole AP-23-305 tested deeper in the deposit, beneath AP-23-304. Results show the gold mineralization in two broad intervals, 47.6 metres grading 3.20 g/t gold from 111 metres downhole and 33.1 metres grading 2.14 g/t gold from 212 metres downhole. Within these intervals are high-grade sub zones including 1 metre grading 22.9 g/t gold, 2.8 metres grading 16.2 g/t gold and 7.38 metres grading 4.77 g/t gold. The High Grade Panel appears to be separating into discrete structures in hole AP-23-305.

Drill Results Impact
The potential impact of these drill results on future resource models can be inferred by comparing the actual grades to those predicted by the existing model (as reported in the 2023 prefeasibility study1). Drilling that outperforms (i.e., is higher grade or wider than) the model may be expected to improve the grade and size of future resource and reserve estimates. Using a 5 g/t cut-off grade provides a useful benchmark to the most financially impactful ounces in an underground mining scenario.
At a 5 g/t cutoff, hole AP-23-303 has a 14% increase in gold grade when compared to an expected intercept calculated from the existing resource model. Using the same criteria; AP-23-304 has a 3% increase compared to the expected intercept from the resource model and AP-23-305 has a 307% increase compared to the expected intercept from the resource model.

Table 2: Drill Hole Details
The Company has completed the High Grade Panel drilling program that will be included in the resource update in November. A total of eighteen holes drilled in 2023, for a total of 3,219 metres, will be incorporated into the updated resource estimate.
The Company is now swapping rigs for a smaller, more portable rig to commence drilling on shallow exploration targets close to the High Grade Panel.
The Company is hosting a webinar tomorrow (September 7th) at 11am Pacific/2pm Eastern time to provide an update on the progress made over the summer at Ana Paula. The company will provide a detailed review of the progress made with the re-scope to date, the catalysts for the remainder of 2023 and the options ahead to rapidly bring Ana Paula into production.

Quality Assurance / Quality Control
Core samples were shipped to ALS Limited in Santiago Queretaro, Queretaro for sample preparation and for analysis at the ALS Laboratories in North Vancouver. The North Vancouver ALS facility is ISO/IEC 17025 certified. Gold was assayed by 30-gram fire assay with atomic absorption spectroscopy finish and overlimits were analysed by 50g fire assay with gravimetric finish.
Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's quality assurance / quality control protocol.
