Flagship Asset: Anzá Gold Project

The Company’s flagship project at Anzá is an advanced gold project in the midst of the prolific Mid-Cauca belt that hosts most of Colombia’s major gold projects.

The Anzá Project is now 100% owned by the Company following completion of a Share Purchase Agreement (“SPA”), announced 28th November 2024, whereby the Company purchased all of the shares of its previous JV partner.

Over 50,000m has been drilled at Anzá, identifying extensive high-grade gold mineralisation at the APTA and Pepas prospects in the centre of the project. Work programs are now focussed on advancing Pepas to a Mineral Resource Estimate (MRE) and assessing the potential of the remainder of the (largely untouched) 330km2 of licences.

The Company is also earning equity in an early-stage gold/silver project in the Patagonia region of Argentina (El Pantano). Drilling commenced in November 2025 and it is expected that the Company will move to 100% ownership of the project in early 2026.

Vision and strategy

A clear strategy built around quality projects, experienced execution and prudent risk management

<p><strong>Our vision</strong> is to be the preferred vehicle for investors to gain exposure to high quality exploration projects, in key commodities, in the most prospective jurisdictions.</p>

Our vision is to be the preferred vehicle for investors to gain exposure to high quality exploration projects, in key commodities, in the most prospective jurisdictions.

<p><strong>Our strategy</strong> is to acquire and develop a diversified portfolio of high-quality assets as efficiently as possible to maximise shareholder returns.</p>

Our strategy is to acquire and develop a diversified portfolio of high-quality assets as efficiently as possible to maximise shareholder returns.

We will focus only on projects (advanced and early stage) that have the potential to host tier one mineral deposits and we will operate those projects to the highest professional and technical standards. 

We will provide our shareholders exposure to a diversified package of assets and commodities, we will manage risk, develop optionality and then assess and pursue the options that provide the greatest returns to our investors.

We aim to set ourselves apart by focussing on the assets, rather than spin, speculation and promotion. 

We will operate in a lean and efficient fashion, keeping overhead low and putting our funds into the ground. 

We will stick with what we know and focus on projects and jurisdictions that leverage our skills and operating experiences and not expose the company to risk that we are not able to manage.
