(Alliance News) - Orosur Mining Inc on Monday said it has begun infill drilling at its Pepas gold prospect in Colombia as it works towards a maiden mineral resource estimate, following positive conceptual studies suggesting near-term production potential.
Shares in Orosur were up 15% at 8.80 pence in London on Monday afternoon.
The South America-focused minerals explorer and developer said the decision follows encouraging internal and external studies showing the surficial and high-grade nature of mineralisation at Pepas could support economic development, especially amid high gold prices.
The company has redeployed its drill rig to carry out between 1,500 and 2,000 metres of infill drilling by November, with a view to publishing a resource estimate in December.
The work is being supported by external geological consultants, who are also assessing the nearby APTA deposit to support potential future resource modelling there.
The Anza project, located in Colombia's Mid-Cauca gold belt, is fully owned by Orosur following its acquisition of the former joint venture partner, Minera Monte Aguila, in November 2024. The project has existing infrastructure and is near multiple large gold and copper deposits.
Drilling at Pepas has returned high-grade intercepts since exploration resumed in late 2024. Orosur said it will continue surface mapping and sampling at other prospects in parallel, including Pepas North and El Cedro, while preparing to restart exploration drilling later this year.
Work is also progressing at the El Pantano project in Argentina, with drilling targeted before year-end, the company.
