Vancouver, BC, Canada – June 3 2015 – Miranda Gold Corp. (“Miranda”) (TSX-V: MAD) and Prism Resources Inc. (“Prism”) (NEX:PRS.H) are pleased to provide an update on work completed on the Cerro Oro project, Caldas Department, Colombia.
Cerro Oro is a robust low-sulfidation epithermal gold system with the potential to provide substantially higher grades than the typical low-grade porphyries seen in the Cauca Belt. Geologic investigations at Cerro Oro suggest that high-grade feeder veins act as conduits to mineralize adjacent permeable and well fractured wall rock over substantial widths.
Reconnaissance prospecting, mapping and 286 channel samples by Miranda in the last year have identified numerous 1-2m wide, high-grade gold veins, coarse stibnite (+/- gold) veins and broad zones of lower grade fracture-controlled, stockwork and disseminated gold mineralization. Visible gold can be panned from almost any grade range of channel samples, and also from all drainages on the project. Hydraulic mining of gold from insitu rock in creek beds has a long history in the district.
The veins provide assay results over 1 to 2m widths from less than 3 g Au/ up to 15 g Au/t. Eleven small artisan adits on the property explore parallel veins along a 1.5km northeast strike length. Locally fractured wall rock adjacent or distal to the veins carry values from less than 0.300 g Au/t up to 2m @ 7.04 g Au/t and 6.5m @ 1.94 g Au/t. The best and most consistent wall rock values occur in drainages that parallel the northeast trend of adits. Exposure is extremely limited outside of drainages and adits, but mapping suggests alteration and mineralization occur over a 1.5sq km area.
The veins display two stages of abundant adularia. Bladed quartz after calcite is observed on artisan mine dumps. Adularia and bladed quartz both indicate proximity to boiling zones, which can be associated with bonanza grade gold mineralization. Multistage quartz and particularly multistage adularia can represent overprinting mineralization events that enrich gold vein grades. Commonly stibnite (Sb) occurs as a high-level mineral above gold in epithermal veins. Thus the coarse stibnite rich-gold poor veins may contain high-gold at depth.
The exploration model for Cerro Oro is for a series of parallel northeast trending, high-grade veins, that occur internal to broad zones of lower grade gold in surrounding permeable wall rock.
Cerro Oro is a concession contract and two concession applications approximately 120 km south of Medellin that cover approximately 1,100 hectares and lie within the resource-rich Middle Cauca Belt in the Caldas department. Cerro Oro appears to be one of a cluster of multi- square kilometer epithermal gold systems that includes Marmato within a northeast structural trend. Marmato (12-14M ounces gold) owned by Gran Colombia Gold is only 14km northeast of Cerro Oro.
Planned exploration is straightforward and efficient and drill targets can be advanced quickly. The vein geometries will be defined with trenching and sampled, and then trenching will be extended perpendicular to the veins to identify better widths and grades of mineralized wall rock. Auger or hand dug sampling pits will be assayed along and beyond the 1.5km extent of known veins. Drilling will proceed to test high-grade vein and lower grade adjacent wall rock exposed at surface. Completing a pending surface agreement with a large private land owner, the trenching of veins and wall rock and soil anomaly definition could start in July, 2015. Exploring parts of the 1.5km vein trend a will require the completion of a Consulta Previa (A requirement to advise local Indigenous Peoples previous to exploration work) currently in progress. Drilling could proceed in early 2016.
Prism and Miranda are very excited to be exploring Cerro Oro together; a project which appears to contain an epithermal system of the scale of Marmato and within the same structural belt that controls Marmato.
