Tolu Minerals Limited is investing AU$15M in an ambitious exploration program along a 10km gold corridor. Deploying seven diamond drill rigs and leveraging advanced surveys and historic data, the company aims to significantly expand its gold resource and production, promising long‑term growth for investors.

Tolu Minerals Limited has embarked on an intensive AU$15 million exploration program to expand its existing Mineral Resource Estimate along the Tolukuma gold mineralised corridor in Papua New Guinea. The project will see the deployment of a fleet totaling seven diamond drill rigs—four surface and three underground—to execute an ambitious 30,000‐meter drilling campaign over the next two years. This clearly signals Tolu’s focus on unlocking additional high-grade gold, silver, and copper resources in areas near its current mining lease, ML104, as well as testing regional targets. Advanced airborne magneto-telluric (MT) surveys along with detailed geochemical data have identified several drill-ready targets along a 10km strike length, including prospects such as Mt. Sen, Kimono, the 120 vein, Kunda North, Miliahamba, Taula, and Duma-Dilava. The company’s strategic plan includes a comprehensive surface geological mapping, trench sampling, and multi-element geochemical survey that will complement the diamond drilling. Recent survey data, with high resolution MT flown at 75m line spacing over a 26km² block adjacent to the mine, has further refined the exploration targets. Historical drilling data and assays from nearby epithermal veins have reported significant gold values, with some intersections revealing multiple meters of mineralisation at high grades. Tolu’s management believes that the data not only supports the planned increase in near-surface mineralisation but also points to extensive potential for regional resource expansion. Management is confident that this rigorous exploration phase will grow production and extend mine life while providing a springboard for additional projects in their portfolio. Chief Executive Iain Macpherson and Executive Group Geologist Chris Muller emphasized that the company’s new accelerator capital and enhanced drilling capacity are key to unlocking the transformative discovery potential in one of Papua New Guinea’s most promising gold districts. From a market perspective, the news carries a bullish sentiment as the extensive drilling program and robust technical indicators point to a significant potential increase in the resource base. The integration of recent airborne MT data with historical geological and assay results suggests a strong pipeline of drill-ready targets. However, there is a degree of caution among observers who note that exploration programs of this scale carry inherent risks in execution and conversion of discovered resources into mineable reserves. Ultimately, the outlook remains positive for Tolu Minerals Limited as it underlines confidence in a measured yet transformative expansion of its mining operations.
