Additional Drill Targets Identified through Deep Sensing IP Geophysics at the Soledad Copper-Gold-Silver Prospect, Central Peru.
Mariana Resources Ltd, the AIM listed exploration and development company with projects in South America and Turkey, has provided an update on the results obtained from the Deep Sensing IP geophysical survey at the Soledad Copper-Gold-Silver Project, Central Peru.
The Deep Sensing IP survey was completed on a 2 km x 3 km block covering the central portion of the Soledad property, where Mariana drilling in 2014 confirmed the existence of both high grade Cu-Au-Ag breccia pipes and porphyry Cu-Au style alteration/mineralisation at depth. The Deep Sensing IP data were acquired along 6 north-south survey lines spaced 400 m apart, and whilst relatively wide spaced and low resolution, compliment existing IP data for Soledad by extending the nominal depth of investigation from 225m to approximately 500m. These new geophysical data, together with additional surface geochemical and PIMA sampling completed by Mariana’s field crews, have resulted in 3 new target areas being identified for the 2015 drill program at Soledad. More detailed compilation of the target areas is in progress.
Whilst further detailed analysis of the Deep Sensing IP data is currently in progress, no significant chargeability anomalies appear to have been delineated within the upper 500m at Soledad. However, the 2014 drill program indicated that the host andesite volcanic rocks contain elevated concentrations of pyrite and these moderate, relatively near surface responses and the high conductivity of Soledad Central could potentially be masking chargeability responses from greater depths. As a result, a combination of known geological relationships (especially data from SDH-12) together with the available geophysical and geochemical data will guide drilling on an interpreted porphyry Cu-Au target at depth.
Chief Executive Officer, Glen Parsons today commented “The deeper geophysics, specifically the high conductivity anomaly below Breccias 4, 5 and 6 indicate the possibility of a root zone of these significantly mineralised breccias intersected in the last campaign. The combination of the drilling and IP results has assisted us in identifying the potential for a large breccia body or a porphyry intrusive which has fed these mineralised breccias. These results have enhanced targeting for the proposed March drill program which will allow us to test the new target areas to depths of around 500m.”
“Furthermore Mariana has staked some 17,000 hectares of new prospective ground, of which 12,800 Hectares has now been granted in its own name (100%) adding to its portfolio in Peru which is gaining critical mass , with the balance to be settled with overlapping claims. This staking follows portfolio rationalisation by Goldfield’s as well as other Junior explorers. The properties will be evaluated in the short term in order to ascertain whether we embark on exploration ourselves or by way of JV partners. We look forward to updating the market with our exciting portfolio developments.”
