Felix Gold Secures DOE Selection for $18M Treasure Creek Antimony Facility

Felix Gold Lands DOE Selection for up to US$18 Million at Treasure Creek Antimony Facility

Felix Gold Limited (ASX: FXG) has reported that the U.S. Department of Energy (DOE) has selected its Treasure Creek Antimony Pilot Processing Facility for award negotiations covering up to US$18 million in federal funding. The selection places Felix Gold among just nine projects chosen nationally under a broader US$162 million critical minerals programme, according to the ASX announcement released on 19 August 2026.

For investors, the most immediate point is clear: the proposed funding is non-dilutive. If negotiations are completed and a formal funding agreement is executed, the award would be a grant rather than equity financing, meaning no new shares would need to be issued to support this part of the pilot facility.

"The U.S. Department of Energy has selected Felix Gold for up to US$18 million because of what we are building: U.S. ore to U.S. metal," said Joe Webb, Executive Director.

"DOE has completed its own technical, financial and security evaluation and selected this project as one of nine nationally. If successful, this is non-dilutive capital at no cost to shareholders. Our strategy has never depended on federal money. It is accelerated by it."

What the DOE Selection Covers

According to the announcement, the selected applicant is Felix Gold Alaska Treasure Creek Inc., the company's wholly owned U.S. subsidiary. The award process sits under funding opportunity DE-FOA-0003583, part of the Infrastructure Investment and Jobs Act Mines & Metals Capacity Expansion programme.

Felix Gold stated that Treasure Creek was selected under Topic Area 2b, a category aimed at projects with previously developed pilot-scale facilities being advanced from prototype stage toward pre-commercial demonstration. In simple terms, this means the programme is focused on projects already at an advanced technical stage, rather than very early concepts.

The DOE programme is overseen by the Advanced Mining and Mineral Production Technologies Office under the Office of Critical Minerals and Energy Innovation (CMEI), with project administration through the National Energy Technology Laboratory (NETL).

The main award details disclosed in the ASX announcement are set out below.

The proposed company contribution is 26.8%, or about US$4.8 million, and Felix Gold confirmed this would be provided in-kind. That means the contribution is proposed to come through goods or services — in this case ore supply — rather than a direct cash payment.

What "Selected for Negotiation" Means for Investors

This part of the announcement requires careful reading. The DOE has selected the project for award negotiations, but this is not yet the same as receiving a binding grant.

According to Felix Gold, the next step is to work with the DOE to finalise the scope of work, budget and schedule for the pilot programme. Furthermore, the company stated that the funded programme scope will differ from the one originally proposed in January 2026, because the federal share has been reduced to US$18 million — a condition already accepted by the company.

The ASX announcement also makes clear that several conditions remain attached to the selection:

1. Reduction of the federal share to US$18 million
2. Implementation of mitigation measures identified by the DOE Office of Research, Technology and Economic Security
3. Successful completion of award negotiations, which may take up to 120 days
4. Execution of a funding agreement by a DOE Grants Officer

The DOE has also stated that selection for negotiation is not a commitment to issue an award or provide funding. Negotiations may be cancelled, the selection may be rescinded, and the eventual award amount may change.

Even with those caveats, the selection still matters. It indicates that the DOE's review process has already considered the project on technical, financial and security grounds and ranked it strongly enough to proceed into formal negotiations. For a small-cap resource company, that level of external review can be a meaningful marker of project maturity.

Treasure Creek Was Already Moving Before This Announcement

The DOE selection did not start Felix Gold's antimony push. However, the company's announcement framed the award as support for a project already progressing on the ground.

Joe Webb stated that Treasure Creek is already permitted and extracting massive stibnite mineralisation, with direct-shipped ore reported to exceed military-grade concentrate specifications. Felix Gold also said it is well advanced on a multi-year mining permit, with mining operations targeted for June 2027.

Downstream work is also reported to be progressing. According to the announcement, testwork, pilot plant engineering and site selection are well advanced, with a U.S. smelter targeted by end-2027.

It is important to note the company's qualifying language. Felix Gold explicitly stated that these timing statements are aspirational, not production targets, and that no feasibility study, pre-feasibility study or scoping study has yet been completed. Delivery of those timelines depends on permitting, funding, award negotiations and further studies. That distinction is important for investors assessing near-term valuation versus longer-dated execution risk.

Why Antimony Matters and Why Treasure Creek Is Relevant

Antimony is a lesser-known mineral for many retail investors, but it has a range of industrial and defence uses. It is commonly used in flame retardants, ammunition primers, alloys, electronics and military-related materials. Because the United States has limited domestic supply, antimony has been classified there as a critical mineral.

What Is Antimony?

Antimony is a metalloid, which means it has properties that sit between a metal and a non-metal. In mining terms, it is often produced from stibnite, the main ore mineral that contains antimony.

A few terms in the Felix Gold announcement are useful to clarify:

• Stibnite: the main mineral ore of antimony
• Pilot processing facility: a smaller-scale processing plant used to test and refine how ore can be upgraded before a full commercial operation is built
• Pre-commercial demonstration: a stage where a process has moved beyond the lab and prototype level, but is not yet full-scale production
• Military-grade concentrate: an antimony concentrate quality that meets strict purity requirements for defence-related uses
• Direct-shipped ore: ore that can potentially be sold or processed with limited upgrading, depending on market and customer requirements

For investors, the importance of antimony comes back to supply and purity. If a project can produce a high-grade, clean concentrate from domestic ore, it may have an advantage in industries requiring reliable supply and strict specifications.

Felix Gold stated that Treasure Creek hosts about 90% antimony-bearing minerals with virtually no deleterious elements. Deleterious elements are unwanted impurities that can complicate processing or reduce product quality.

The announcement also highlighted several project attributes:

The point about no federal land is especially relevant in a U.S. permitting context. According to the company, this may reduce permitting complexity compared with many other U.S. critical minerals projects. Felix Gold is participating in the State of Alaska OPMP-coordinated permitting process for longer-term planning and agency review.

Frontier Antimony Refinery Adds a Downstream Pathway

Another important part of the announcement is the role of Frontier Antimony Refinery, a Delaware-incorporated company that is wholly owned by Felix Gold.

According to management, Frontier was established as a U.S. vehicle for U.S. government programmes and U.S. capital markets. It has secured the rights to Treasure Creek antimony and is being developed with its own pathway to U.S. capital markets. Felix Gold also said a seed funding process is currently underway within Frontier.

This structure matters because it suggests Felix Gold is trying to develop more than a mine. The strategy outlined in the announcement is an integrated domestic supply chain, linking U.S. ore extraction with U.S.-based refining and metal production. That does not remove execution risk, but it does provide more context for why the DOE grant process is focused on a pilot processing facility rather than just upstream extraction.

Gold Remains the Second Part of the Alaska Story

Although the DOE announcement is centred on antimony, Felix Gold also used the release to remind the market that it is advancing gold opportunities in Alaska's Fairbanks Mining District.

The company described itself as the largest landholder in the district, located 30 km from Kinross's Fort Knox mill, which it said is a Tier 1 operation actively seeking third-party ore. In addition, Felix Gold noted that the same infrastructure, permitting pathway and team support both commodities.

For investors, this creates a dual exposure. Antimony is the near-term focus of this announcement, while gold provides additional project optionality in the same district without requiring a completely separate operating footprint.

Key Milestones to Watch After the DOE Selection

The immediate focus now shifts from selection to execution. The next few months should provide more clarity on whether the DOE negotiations convert into a formal funding agreement.

The announcement also stated that the DOE selection has no impact on Felix Gold's broader Treasure Creek work programmes, which continue as planned regardless of the negotiation outcome.

Why This Announcement Matters for the Felix Gold Investment Case

The DOE selection brings together several elements of the Felix Gold story in one update. First, it introduces the possibility of up to US$18 million in non-dilutive funding, which is material for a company of Felix Gold's size. Second, it provides external validation through a competitive U.S. federal process. Third, it aligns with an operating plan that the company says is already underway at Treasure Creek.

At the same time, the market will need to balance that upside against the conditions still outstanding. The funding is not yet committed, negotiations can still change the scope or amount, and the broader development timeline remains dependent on studies, permitting and further funding.

Key Investor Takeaway

Felix Gold has been selected by the DOE for negotiations over up to US$18 million in grant funding for its Treasure Creek Antimony Pilot Processing Facility. The proposed funding is non-dilutive, the company's cost share is to be provided in-kind, and the project was one of nine selected nationally. The next major catalyst is the outcome of DOE negotiations, which may take up to 120 days.
