O3 Mining Announces Mobilization of Two Drills at Marban Project

O3 Mining Inc. OIII OIIIF is pleased to announce the mobilization of two drills at Marban Engineering, which will be focusing on the Upper Camflo area and Orion deposit. The drilling is part of a 24,800 metre exploration program on the Marban Project.


  • O3 Mining to drill 1,500 metres near surface on the Upper Camflo area along the up-dip extension of a gold-bearing structure identified during the compilation of historical exploration drilling completed by Barrick Gold on the former Camflo mine.
  • O3 Mining to drill 900 metres near surface around the former Orion mine to confirm possible ore material left above and below the historical mining stopes.

O3 Mining's President and Chief Executive Officer, Mr. Jose Vizquerra commented: "We are encouraged by the compilation work completed on the Camflo and Orion deposits and are excited to continue our drilling campaign on our Marban property in an effort to expand resources. Proximal to the historic Camflo mine, Upper Camflo and Orion offer the possibility of generating near surface resources in the halo of the past producers."

The compilation of Barrick Gold's historical drilling revealed parallel zones north of the Camflo mine. One of the zones was intersected by a series of holes drilled horizontally and toward the north from the border of the property at the 2400 mining level (700 metres from surface). The planned program will test an area of 800 metres along strike for near surface gold mineralization from the border of the property.

The Orion mine produced 22,367 gold ounces from 131,000 tonnes at 5.3 g/t Au from 1987 to 1990. The zone is outcropping and surface channel samples revealed a high-grade and wide auriferous zone where the best channel samples returned 21.8 g/t Au over 11.2 metres (Press Release - September 6, 2022). The planned program comprises three drill holes to validate historical high-grade assays outside the near surface mining stopes.
