HIGHLIGHTS:

• Debt Facility to fund completion of the Decline, Test Mining and processing of a Bulk Sample
• This self-funding path is an innovative means of funding the advancement of the Ana Paula Project and minimize equity dilution
• Funding expected to be repaid within 30 months from drawdown through sale of gold from the bulk sample
• Completion of the decline reduces future capital expenditure and future drilling costs
• A component of the debt funding and additional cash flows generated from the Test Mining to be used for additional drilling to grow the Ana Paula resource

Heliostar Metals Ltd. (TSXV: HSTR) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") is pleased to report it has entered into a non-binding letter of intent in respect of a senior secured debt facility (the "Facility") for the aggregate principal amount of US$20 million (the "Loan Amount") with an expected fixed 10% rate of interest with a syndicate of lenders led by a New York based Financial Institution (together, the "Lenders").

The net proceeds of the Facility will be used to advance the underground decline and complete test mining to process a bulk sample from the Ana Paula deposit in Guerrero, Mexico ("Test Mining").

The Facility is expected to have a 30-month term and is subject to an annual interest rate of 10%, payable semi-annually. The Facility is expected to be assured by customary security commitments, including over the Ana Paula Project. The facility allows for the early repayment of the Facility at any time, and upon the sale of gold ounces. The facility calls for Heliostar to make repayments equal to the number of ounces of gold sold multiplied by US$1,850 per ounce (the "Reference Price") after deducting operating expenses.

Heliostar CEO, Charles Funk, commented, "Finding a self-funded solution that diminishes the amount of equity dilution to advance the development of the Ana Paula Project and undertake a Test Mining program has been the Company's focus in 2024. Today's announcement puts Heliostar on the front foot to continue to de-risk the Ana Paula project and accelerate its path to commercial production. Funding from the financing will be used to complete the decline and undertake test mining. It will additionally, permit drilling to add more ounces to the high-grade core of the Ana Paula deposit. Funds from the sale of gold produced from the bulk sample are anticipated to repay the principal and interest of the loan and the floor price for a portion of the test mining ounces minimizes completion risk. We are excited to advance towards our goal of mining the first gold ounces from the Ana Paula Project in 2025!"

Test Mining

The Company considers Test Mining to be a compelling development approach at Ana Paula as it provides several advantages, including:

• Producing cash flow from the sale of gold produced from the bulk sample to pay for the decline and Test Mining infrastructure to significantly reduce equity dilution
• Funding drilling with a focus of adding additional high-grade gold ounces, which can have a significant impact on the Net Present Value of the project
• Decreasing the forecasted capital expenditure of the full scale project by developing the decline and initial stopes in advance
• Providing valuable information to further de-risk grade reconciliation, stope design and metallurgical recoveries prior to final mine design
• Decreasing infill and expansion zone drilling costs by providing underground drilling platforms

Ana Paula's current infrastructure, including its open pit mine permit, partially completed decline and connection to grid power should allow for this bulk sample plan to proceed quickly. Engineering undertaken in Q1, 2024 has been completed to ensure the design for Test Mining maximizes the long-term mine plan at Ana Paula.

Financing Details

Interest Payment: The Facility is expected to bear a 10% per annum coupon, calculated and payable semi-annually, and will mature after a 30-month term.

Gold Price Linked Premium: Heliostar is expected to enter into gold swaps with the Lenders at closing of the Financing (the "Closing") tied to a gold price equal to the Reference Price of US$1,850 (the "Gold Premium"). At certain dates in the future tied to Heliostar's production and sale of gold from Test Mining, if the spot price of gold is greater than the Reference Price, Heliostar will pay the Lenders the difference between the spot price and the Reference Price, multiplied by the "Payment Swap Ounces". Payment Swap Ounces is the lesser of: (i) the ounces sold by Heliostar that triggered the mandatory revenue prepayment and (ii) the difference between the Total Swap Ounces and the sum of all previous Payment Swap Ounces sold by Heliostar. If the spot price of gold is less than the Reference Price, the Lenders will pay Heliostar the difference between the spot price and the Reference Price, multiplied by the Payment Swap Ounces.

Warrants: In connection with the Facility, the Company will issue to the Lenders an aggregate of 17,239,668 share purchase warrants (the "Warrants"). Each Warrant will entitle the Lenders to acquire one common share within 30 months of closing at an exercise price of (i) as to 8,619,834 of the Warrants, $0.40 per share, and (ii) as to 8,619,834 of the Warrants, $0.55 per share.

Use of Proceeds: The net proceeds of the Facility are expected to be used to fund (i) development of the decline and Test Mining of a bulk sample, (ii) drilling at the Ana Paula deposit, and (ii) facility interest until production has commenced.

Closing: Closing is subject to the execution of definitive documents, receipt of all necessary approvals and the completion of the Lenders' technical due diligence. There is no assurance that the Facility will be completed on the terms set forth above or at all. Closing is anticipated in Q3, 2024.

There can be no assurance that a definitive agreement with respect to the Facility will be executed or, if executed, whether the funding will be consummated.

The Company intends to pay a qualified non-related party a finder's fee (the "Finder's Fee") equal to 2% of the Loan Amount. Subject to approval by the TSX Venture Exchange, the Company intends to pay the Finders' Fee half in cash and half in common shares at a deemed price of $0.30 per share.
