(Alliance News) - Orosur Mining Inc on Tuesday said it had detected new mineralised zones at the APTA prospect.
APTA is located in the centre of the Anza project in Colombia's Mid-Cauca gold belt, and is the prospect around which the project was originally based.
Toronto-based Orosur owns 100% of Anza through its subsidiaries, Minera Anza and Minera Monte Aguila.
The minerals explorer and developer targets South America. Its shares rose 2.1% to 20.16 pence on Tuesday around noon in London, having more than doubled over the past year.
Orosur said the first new drill hole at the APTA prospect had returned 229.7 metres graded at 0.88 grammes of gold per tonne. Other high-grade intervals included 6.85 metres at 2.15 grammes per tonne, 7.65 metres at 7.07 grammes per tonne and 4.7 metres at 3.95 grammes per tonne.
According to the company, these results "substantially" boost APTA's prospectivity. It has identified three areas where follow-up may be required.
Chief Executive Brad George commented: "APTA was always tantalising but misunderstood as previous drilling was never pulled together into a coherent picture. After almost 15 years, this is now being done, and looking exciting."
Also part of the Anza project are the El Cedro and Pepas prospect. Orosur published a mineral resource estimate for the latter back in February.
Assuming extraction via open pit mining, the estimate is 1.1 million tonnes at a grade of 5.46 grams per tonne for 201,000 ounces of gold in the indicated mineral resource category and 0.19 million tonnes at a grade of 2.99 g/t gold for 19,000 ounces of gold in the inferred mineral resource category.
