Flagship Minerals Receives $5.8M From RK Lithium Sale

Flagship Minerals Completes US$4.0 Million RK Lithium Sale and Pivots to Gold and Copper

Flagship Minerals Limited (ASX: FLG) has confirmed receipt of US$4.0 million, or about $5.8 million, from the sale of its 100%-owned RK Lithium Project in southern Thailand, completing a binding transaction first announced on 25 June 2026. According to the ASX update, the payment was received in full and in cash, giving the company fresh funding as it transitions toward a more focused portfolio centred on gold in Chile and copper in Canada.

The announcement matters because it changes both the company's balance sheet and its investment profile. With the lithium asset sold and discussions continuing on the sale of the Khao Soon Tungsten Project, Flagship is moving away from a multi-commodity portfolio and toward a gold and copper only explorer and developer.

"The divestment of the RK Lithium Project brings US$4.0m or ~$5.8m cash into Flagship. Flagship will focus on progressing its 2.1Moz Isidora Gold Project in Chile to feasibility. Flagship is also reviewing the Whipsaw Copper Project in Canada for a potential spin-out via an ASX listing," said Paul Lock, Managing Director.

RK Lithium Sale Completed With Full Cash Payment Received

In the ASX announcement, Flagship stated that a Thai-based syndicate led by privately held Pendulum Auto Co., Ltd entered into a Sale and Purchase Agreement (SPA) to acquire the RK Lithium Project for US$4,000,000. The company has now confirmed that the full amount has been received.

That transaction structure is relevant for investors because it appears simple and immediate. There is no reference in the announcement to deferred payments, equity consideration or staged earn-ins, which means the company has converted the asset directly into cash.

Key transaction details are set out below.

The company also noted that the exchange rate moved between the signing date and payment confirmation date. At the time of the original sale announcement, the AUD/USD rate was about 0.6900, while at the date of the latest release it was about 0.6990. The US dollar sale value, however, remained fixed at US$4.0 million.

For investors, the practical point is straightforward. Flagship now has additional cash on hand without issuing new shares to raise it.

Portfolio Transition Moves Toward a Two-Asset Structure

The quarterly-style significance of this update lies less in the lithium asset itself and more in what the sale enables. According to the announcement, discussions are already underway regarding the sale of the Khao Soon Tungsten Project, which management described as one of the larger tungsten exploration projects in south-east Asia.

If that second divestment is completed, Flagship would be left with two core assets:

• The Isidora Gold Project in Chile
• The Whipsaw Copper Project in British Columbia, Canada

This would leave the company with a clearer commodity focus and a simpler asset base. For smaller ASX resource companies, that can matter because a cleaner structure often makes capital allocation easier to follow and may help investors assess which project is expected to drive value.

Isidora Gold Project Becomes the Main Development Focus

In the announcement, management said the immediate focus is to progress the 2.1 million ounce Isidora Gold Project in Chile toward feasibility. Isidora sits east of Copiapó in the Atacama region of northern Chile and covers about 120 square kilometres, comprising two Exploitation Concessions and 34 Exploration Concessions.

Flagship referenced the JORC (2012) Mineral Resource Estimate first reported on 14 May 2026, which outlined a total resource of 115.2 million tonnes at 0.56 g/t gold for 2,093,000 ounces.

The resource breakdown is shown below.

The reported cut-off grades were:

• Oxide: 0.16 g/t Au
• Transitional: 0.27 g/t Au
• Sulphide: 0.31 g/t Au

A key feature of the estimate is the level of confidence in much of the resource. Around 91.0% of Isidora's ounces fall within the Measured and Indicated categories combined. That is important because these categories generally provide a stronger basis for engineering and economic studies than Inferred material alone.

For investors assessing development-stage gold projects, this makes Isidora the central asset to watch. Progress toward feasibility could become the main benchmark for measuring execution over the next phase.

Whipsaw Copper Project Adds Large-Scale Copper Optionality

Flagship's second core project is the Whipsaw Copper Project in British Columbia. The ASX release describes Whipsaw as a large-scale copper porphyry located in an infrastructure-rich mining setting, about 160 kilometres east of Vancouver and 17 kilometres west of Hudbay's Copper Mountain project.

The project covers about 66 square kilometres. Based on historical drilling, soil geochemistry and geophysical data, Flagship has reported a JORC (2012) Exploration Target across a mineralised system with 3.7 kilometres of strike length and up to 1.2 kilometres of width, open in multiple directions.

It is important to note, as the company does, that the Exploration Target is conceptual in nature. The announcement states there has been insufficient exploration drilling to estimate a Mineral Resource at this stage, and it remains uncertain whether further work will lead to one.

That distinction matters considerably. A Mineral Resource and an Exploration Target are not the same thing, and investors should treat them differently when assessing project maturity.

Management is furthermore reviewing a potential spin-out of Whipsaw into a dedicated ASX-listed vehicle. According to the announcement, any such spin-out would be subject to shareholder and regulatory approvals, including ASX approval.

Why Resource Confidence Matters at Isidora

Mining announcements often use classification terms that can appear technical at first glance. In practice, however, these categories are one of the clearest indicators of how far a project has progressed.

A Mineral Resource Estimate (MRE) is a formal estimate of how much mineralised material is present and what grade it carries, prepared under the JORC Code (2012). The resource is then divided into categories based on confidence in the geological data.

How Are JORC Resource Categories Defined?

• Measured Resource: Highest confidence category. Drilling and sampling are close enough together to support a high level of certainty in tonnes and grade.
• Indicated Resource: Good confidence, but with more uncertainty than Measured. Often suitable for mine planning studies at an earlier stage.
• Inferred Resource: Lower confidence category based on more limited information. Further drilling is usually needed before detailed development decisions can rely on it.

For Flagship, this matters because Measured plus Indicated resources account for about 1.904 million ounces, or roughly 91.0% of the Isidora total. In development terms, that gives the company a stronger starting point for feasibility work than a resource dominated by Inferred ounces.

Put simply, higher-confidence resources can make future technical studies more meaningful. They do not guarantee an economic mine, but they generally reduce one layer of geological uncertainty.

Understanding Whipsaw's Copper Porphyry Setting

Whipsaw is described as a copper porphyry project, a term that is common in mining but less familiar outside the sector. A porphyry deposit is a large mineral system that can contain copper, and sometimes gold, silver or molybdenum, spread through a broad rock volume rather than concentrated in narrow veins.

This style of deposit is important globally because many large copper mines are porphyries. They can support substantial tonnage, although grades are often moderate relative to smaller, higher-grade deposit types.

At Whipsaw, the company has used a copper equivalent (CuEq) figure to express the combined value of copper, molybdenum, gold and silver as a single copper percentage. This can help investors compare multi-metal systems more easily, but it depends on assumptions such as metal prices and recoveries.

The ASX release also included the standard caution that all elements used in the metal equivalent calculation are considered by Flagship to have a reasonable potential to be recovered and sold. However, CuEq should be viewed as a modelling tool rather than a direct substitute for detailed metallurgical and economic analysis.

Near-Term Milestones Investors Are Likely to Watch

The announcement sets out a fairly clear sequence of corporate priorities. Rather than expanding across multiple fronts, the company appears to be concentrating on divestments and asset-specific advancement.

The main milestones include:

1. Completion of the RK Lithium sale, which has now occurred.
2. Progress on the Khao Soon Tungsten sale, with discussions underway.
3. Advancing Isidora toward feasibility in Chile.
4. Assessing a possible ASX spin-out of Whipsaw, subject to approvals.

These priorities can be summarised as follows:

For investors, the next valuation markers may differ by asset. At Isidora, attention is likely to centre on feasibility-related technical work. At Whipsaw, the market may focus more on corporate structure and whether a spin-out proposal becomes formal.

What This ASX Update Means for the Investment Case

This ASX announcement does not report drilling or a new resource. Its significance lies instead in capital, focus and portfolio design.

First, the company has added US$4.0 million in cash through an asset sale rather than equity issuance. That may help fund work programmes whilst limiting dilution. Second, Flagship has reiterated a clear operational priority around Isidora, where a 2.1Moz gold resource with a high proportion of Measured and Indicated ounces gives the project a defined development pathway.

Third, Whipsaw remains a separate copper growth angle with scale, but at an earlier and more conceptual stage. The remaining question is execution. A completed tungsten sale would simplify the portfolio further, whilst progress at Isidora and clarity on Whipsaw's structure could determine how the market values the company's next phase.

In summary, the update presents Flagship as a company moving away from lithium and tungsten and toward a more concentrated gold and copper position. The cash has been received, the transition has started, and the next steps are now tied to project advancement rather than transaction certainty.
