Highlights:
Vancouver, Canada, August 3rd 2023 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG1) (“Heliostar” or the “Company”) is pleased to report progress on re-scoping of the current Pre-Feasibility Study ( the “PFS”) at the Company’s Ana Paula Project in Mexico (“Ana Paula” or the “Ana Paula Project”) to evaluate potential underground mining scenarios. The Company is evaluating three underground mining scenarios, with different cut-off grades and mining rates, that are being advanced for more detailed evaluation and comparison. All three demonstrate the potential to deliver high grades early and throughout the mine life.
Heliostar CEO, Charles Funk, commented, “We are quickly advancing the re-scoping of Ana Paula towards an underground mine. The High Grade Panel is shallow and wide with a favourable orientation for productive underground mining. The Company is refining three scenarios to choose the approach that maximises the profitability of mining and shortens the timeline to production. One of the keys to achieving this is mining high grades early in the mine life, as compared to the open pit scenario. We will choose the best outcome and work through the Feasibility Study in 2023. We expect further improvements to the mine economics as current analysis does not include the excellent results from Heliostar’s 2023 drill program.”
Gold Distribution within the Resource
Ana Paula’s 2023 PFS measured and indicated resource contains an average of 5,350 ounces of gold per vertical metre between 725-950 metres of elevation (immediately below surface). The zone ranges between a maximum of 8,540 ounces per vertical metre at 775 metres of elevation and a minimum of 1,080 ounces per vertical metre at 925 metres of elevation. The ounce distribution in the open pit portion of the resource is constrained by the 2023 PFS open pit shell and in the underground portion by a 1.6 gram per tonne (g/t) gold cutoff resource shell.
Figure 1 shows a graphical representation of the contained measured and indicated ounces by elevation within the 2023 PFS resource.
Underground Mining Scenarios
Multiple potential mining scenarios are in review for Ana Paula. The project re-scoping is assessing the most applicable mining scenario with a focus on increasing project economics (NPV and IRR) while reducing initial CAPEX when compared to the open pit mining scenario proposed in the 2023 PFS.
The Company contracted JDS Energy & Mining Inc., who completed the existing decline on the property, to evaluate the options. Currently, the engineers are assessing three scenarios with different cutoff grades and throughput rates for the Ana Paula deposit using the 2023 pre-feasibility study resource model. The Company will refine the options upon receipt of an updated resource model and metallurgical program results, both of which rely on drilling completed in 2023. Metallurgical results will be reported in October and an updated resource model is expected in November 2023.
The best outcome will then be selected and taken through Feasibility Study in 2024.

These forward–looking statements or information relate to, among other things: the exploration, development, and production at the Company’s properties; permitting at the San Antonio project; the release of exploration results; future resource and reserve estimates; and the completion and timing of a feasibility study for the Ana Paula Project.
Forward–looking statements and forward–looking information relating to any future mineral production, liquidity, enhanced value and capital markets profile of the Company, future growth potential for the Company and its business, and future exploration plans are based on management's reasonable assumptions, estimates, expectations, analyses and opinions, which are based on management's experience and perception of trends, current conditions and expected developments, and other factors that management believes are relevant and reasonable in the circumstances, but which may prove to be incorrect. Assumptions have been made regarding, among other things, the price of metals; no escalation in the severity of public health crises or ongoing military conflicts; costs of exploration and development; the estimated costs of development of exploration projects; and the Company's ability to operate in a safe and effective manner and its ability to obtain financing on reasonable terms.
