Heliostar's New Parallel Panel Yields 16m Grading 11.2 g/t Gold within 147m Grading 4.1 g/t Gold at Ana Paula Project

Highlights:

• Hole AP-23-309

  • - 147.05 metres @ 4.13 grams per tonne (g/t) gold including

  • - 16.0 metres @ 11.2 g/t gold in the Parallel Panel

• Hole AP-23-308

  • - 14.8 metres @ 5.06 g/t gold in Parallel Panel

• These results will not be included in the updated mineral resource estimate the Company expects to announce later this month and represents the potential for further resource growth

Vancouver, British Columbia--(Newsfile Corp. - November 8, 2023) - Heliostar Metals Ltd. (TSXV: HSTR) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") is pleased to report results from two diamond drill holes at the Parallel Panel target at the Ana Paula Project in Mexico ("Ana Paula"). These two holes are the first to specifically test the Parallel Panel target, which is 50 metres north of the High Grade Panel, after the Company identified it as new zone of high-grade mineralization over the last few months.

Heliostar CEO, Charles Funk, commented, "Ana Paula continues to outperform our expectations. The Company's improved understanding of the gold mineralization led to the recent recognition of a new Parallel Panel only 50 metres north of the High Grade Panel. Today's results are wide, with high-grade mineralization. In hole AP-23-309, the High Grade and Parallel panels almost connect, returning 147m at 4.13g/t gold which remains open to depth. The Company continues to test its growth targets and remains on target to deliver a resource update this month. These new successes demonstrate that the upcoming resource estimate may already be underplaying the true potential of Ana Paula."

Drill Results

Today's results are the first to specifically target the Parallel Panel. The locations step out from recent drill intercepts and test the target with the optimal north-south orientation. The new holes demonstrate good continuity of width and grade within the Parallel Panel. The gold intercepts demonstrate the strong potential for continued resource growth at Ana Paula.

Hole AP-23-309 is at the eastern end of the currently defined Parallel Panel and returned 147.05 metres grading 4.13 g/t gold from 37.5 metres downhole (Figure 1). Within that, the hole encountered 16.0 metres grading 11.2 g/t gold from 77.0 metres downhole in the Parallel Panel target.

The intercept continues downhole into the High Grade Panel with the two zones almost connecting to create the very long intercept (Figure 2). The hole encountered additional subzones of high-grade gold in the High Grade Panel. Those include 7.0 metres grading 14.5 g/t gold from 112.4 metres downhole and 8.6 metres grading 8.70 g/t gold from 153.5 metres downhole.

Hole AP-23-308 tested the Parallel Panel over 140m west of hole AP-23-309. It is the only hole within the local area that was drilled at the optimal north-south drilling orientation and retuned 14.8 metres grading 5.06 g/t gold. This intercept is open in all directions within the plane of the panel. In the area of AP-23-308, the Parallel Panel is clearly a discrete zone. It is located in the footwall and separate from the High Grade Panel.

Drill Progress

Upon completion of hole AP-23-309, the Company moved the drill rig and completed two holes at the West Breccia exploration target. After West Breccia, the focus will return to the Parallel Panel target where step out drilling is planned from today's results.

Quality Assurance / Quality Control

Core samples were shipped to ALS Limited in Zacatecas, Zacatecas, Mexico for sample preparation and for analysis at the ALS Laboratories in North Vancouver. Each of these ALS facilities are 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 analysed as part of the Company's quality assurance / quality control protocol.
