Orosur Mining completes drilling at Pantanillo gold project in Chile
Orosur Mining Inc. (TSX-V, AIM: OMI) said it is well on the way to defining a NI 43-101 compliant resource at the Pantanillo gold project in Chile and said the drill program of 30 diamond and RC drill holes for 5,637 meters there has now been completed.
The Pantanillo property is optioned from Anglo American Norte S.A, a subsidiary of Anglo American PLC (LSE: AAL). It is located in the Maricunga Belt of Chile, approximately 30 kilometres north of the Maricunga mine operated by Kinross Gold (TSX: K, NYSE: KCG). Drilling has been focused on the Pantanillo Norte target. Orosur took over Fortune Valley Resources’ interest in the property when it acquired Fortune early this year.
Chief executive David Fowler commented: “All of the 24 drill holes received to date were mineralized and the deposit remains open at depth. The recent drilling program at Pantanillo targeted the oxidized portion of the deposit and a scoping study is underway. Assays from the remaining 7 holes of the initial program are expected during May. No further drilling could be completed this summer season.”
“Additionally, exploration work has commenced at the Anillo project in Northern Chile which sits north east of the El Peñon Mine. A regional, first pass mapping program has already been completed and a surface geochemical sampling program is ready to commence,” he added.
Results for the first 9 holes drilled at Pantanillo were reported in mid-April this year. Highlights of the latest results showed an intercept of 25 meters at 0.64 grams per ton gold including 1 meter at 5.68 g/t Au, 54 meters at 0.68 g/t Au including 5 meters at 1.27 g/t Au, 41 meters at 1.50 g/t Au, 20 meters at 1.85 g/t Au and 70 meters at 0.92 g/t Au. All figures are reported with a 0.3 g/t Au cut-off grade.

The Anillo property is optioned from the Chilean state owned mining company, Codelco. The property is located north northeast of the El Peñon mine operated by Yamana Gold Inc (TSX: YRI; NYSE: AUY; LSE: YAU).
Procuction in the third quarter to end-February 2010 was in line with Orusur’s expectations at 12,742 ounces and it remains on track to achieve its production target for the year of 55,000 to 57,500 ounces at US$825 per ounce.
