Heliostar Drills 31.8 g/t Gold over 9.5 Metres within 8.0 g/t Gold over 72.0 Metres in Up-Plunge Target at the Ana Paula Project.


  • Hole AP-23-300

               - 72.0 metres @ 8.0 grams per tonne (g/t) gold including

               - 9.5 metres @ 31.8 g/t gold

  • Hole AP-23-302

               - 52 metres @ 5.0 g/t gold 

  • Hole AP-23-299

               - 11 metres @ 15.8 g/t gold 

  • The up-plunge target is expected to connect into a single block of continuous high grade gold mineralization.  
  • Hole AP-23-300 is 480% better than predicted in the current resource model at a >5g/t cutoff grade

Vancouver, Canada, August 9th 2023 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: 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 four holes continue to assess mineralization up-plunge of the High Grade Panel at the core of Ana Paula. 

Heliostar CEO, Charles Funk, commented, “Drilling at Ana Paula continues to exceed our expectations and deliver impressive gold intercepts.  The headline hole, AP-23-300, is a 480% increase to the current resource model prediction, at a >5 g/t gold cut-off grade. The most easterly of Heliostar’s holes, AP-23-302 was also particularly impactful with an intersection of 51 metres @ 5.0 g/t gold in an area where high gold grades were not modelled in the 2023 PFS resource.  These results validate our belief that we can meaningfully increase the value of the Ana Paula project. The Company continues its well-funded expansion and infill drilling program of the High

Grade Panel. Additional drill results will continue to be announced ahead of the planned resource update in November 2023.” 

Drill Results

Results from this press release are from Heliostar’s up-plunge growth target at Ana Paula.  

Hole AP-23-299 tested the up-dip and central portion of the High Grade Panel.  This hole extended mineralization towards the surface and returned 38.0 metres grading 6.95 g/t gold, including 11.0 metres grading 15.8 g/t gold.

Hole AP-23-300 tested a gap in the high grade in the up-plunge area where hole AP-23-297 had intersected a sub-interval of 24 metres at 8.8 g/t gold.   Hole AP-23-300 returned 38 metres grading 13.4 g/t gold including 9.5 metres grading 31.8 g/t gold to better define the northern extent of High Grade Panel in this area.

Hole AP-23-301 tested deeper beneath AP-23-300 in an area where the panel is narrower.  It intersected 8.5 metres grading 3.0 g/t gold.

Hole AP-23-302 tested a gap in the high-grade mineralization at the far east of the High Grade Panel in an area where no high grade mineralization was modelled in the resource.  It returned a strong intercept of 51.8 metres grading 5.01 g/t gold including 4.7 metres grading 11.6 g/t gold.  This is particularly impactful as it has the potential to infill a large gap in the panel with gold mineralization (Figure 1).

Drill Results Impact

The potential impact of the drill results on future resource models can be demonstrated by comparing the current results to 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-23-299 has an 83% increase when compared to an expected intercept calculated from the existing resource model.  Using the same criteria; AP-23-300 has a 480% increase compared to the expected intercept from the resource model, AP-23-301 has a 63% decrease compared to the expected intercept from the resource model and AP-23-302 was a significant increase as no high grade was estimated in the resource model.

Drilling Progress

The Company is on schedule and on budget with the drilling program.  The Company completed eighteen holes at Ana Paula.  The Company has reported results from twelve holes to date.  Holes AP-23-302 through and AP-23-305 are the Company’s first holes targeting high-grade mineralization further west into the down-plunge target.  The holes intersected sulfide mineralization throughout, particularly AP-23-303.

The Company is finishing two infill holes in the vicinity of hole AP-23-291.  The result will be a cross-section of tightly spaced intercepts and these holes will support resource modelling and provide metallurgical material for analysis.

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.
