Heliostar Submits Environmental Permit Applications for Ana Paula
Heliostar advances Ana Paula permit submission to advance its 2027 construction decision despite lingering cost creep and dilution risks.
Heliostar Metals Ltd. has submitted the Environmental Impact Statement (MIA-R) and Environmental Risk Study (ERA) to SEMARNAT for the Ana Paula underground project in Guerrero, Mexico. This submission represents a critical regulatory milestone toward a formal construction decision, which is now targeted for mid-2027.
The approved design marks a pivot from a previously permitted open-pit operation to an underground mine, a change that reduces surface disturbance by approximately 65%. Key engineering modifications include the implementation of dry-stack tailings, the use of paste backfill, and the construction of a smaller, relocated processing plant.
Management projects that the project will generate approximately 1,500 initial construction jobs and around 600 permanent operational roles, with positions primarily sourced locally.
Heliostar Metals Ltd. (HSTR) submitted a permit application, a necessary and anticipated regulatory step that confirms management’s pivot to an underground mine plan and validates the mid-2027 construction decision timeline. The market has already partially priced in this progression, as evidenced by the stock's recovery from the June 2026 lows. The news reinforces the development thesis but does not alter the financial profile or valuation multiple in a transformative way.
Heliostar Metals Ltd. (HSTR) is a producing gold miner with a diversified portfolio across Mexico and the United States. Its producing assets include the La Colorada mine in Sonora, Mexico, and the San Agustin mine in Durango, Mexico, which are currently generating cash flow through open-pit heap leaching and injection leaching operations.
The company’s development pipeline features the Ana Paula underground project in Guerrero, Mexico, which is targeting first production in the second half of 2028. Additionally, the Cerro del Gallo project in Guanajuato, Mexico, has a completed Preliminary Feasibility Study (PFS), and the San Antonio project in Baja California Sur, Mexico, has a completed Preliminary Economic Assessment (PEA).
In the exploration sector, Heliostar acquired the Goldstrike property in Utah, USA, in the second quarter of 2026, adding a Carlin-style gold resource and antimony potential. The Unga project in Alaska, USA, remains an early-stage exploration asset. The company’s strategy centers on using cash flow from existing mines to fund the development of Ana Paula and expand resources across the portfolio, targeting more than 500,000 ounces of gold per year by 2030.
