Heliostar Files Updated Pre-Feasibility Study to Support

Ana Paula Acquisition

Vancouver, Canada, April 6th, 2023 – Heliostar Metals Limited (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG 1)

(“Heliostar” or the “Company”) reports that it has filed a technical report on an update of the 2017 Pre -

feasibility Study (“PFS”) on the Ana Paula Deposit in Guerrero, Mexico with the securities exchange. The

updated PFS, effective February 28, 2023, reflects current metal prices and input costs.

Heliostar CEO, Charles Funk, comments “Updating the Pre-feasibility study was a key document required

be the securities exchange for approval of the Company’s acquisition of the Ana Paula deposit. Heliostar

has acquired Ana Paula with an initial focus on the High-Grade Panel within the core of the orebody. We

believe shifting from an open-pit plan to an underground plan will lead to a lower CAPEX, a simpler flow

sheet and a more profitable gold mine. Our plan to re-scope Ana Paula has commenced and the company

expects first drill results by the end of May, 2023”
