Miranda And Prism Announce Drill Program Testing Epithermal System At Cerro Oro Project, Colombia
Vancouver, BC, Canada – April 27, 2016 – Miranda Gold Corp. (“Miranda”) (TSX-V: MAD) and Prism Resources Inc. (“Prism”) (NEX: PRS.H) are pleased to announce a planned drill program for the Cerro Oro Project in Colombia. Prism is the funding partner and Miranda is the operator in joint venture. Four to five angle holes totaling 1,000 m are planned. Drilling is anticipated to begin before the end of May 2016.
Miranda has completed geologic mapping and extensive 2-meter channel sampling. Approximately 416 channel samples have been taken. Twenty percent of those samples assay greater than 0.2 g Au/t. Multiple sub-parallel one to two meter width veins are identified within an area of alteration greater than 1 sq km. Locally veins, vein wall rock, and rock unrelated to veins are significantly mineralized. Veins assay as high as 2m @ 12 g Au/t and wall rock and country rock where significantly mineralized assay from 0.5 to 3.0 g Au/t. Samples unrelated to veins have widths up to 6.5 m @ 1.98 g Au/t. These widths and assays come from a database including all rock types, containing assays ranging from non-detectable to 12 g Au/t, with a median value of approximately 0.150 g Au/t.
Outcrop exposure is limited to creek beds. Where accessible in several artisanal mines, veins have been mapped and sampled. Visible fine gold is common in crushed samples of both fresh rock and saprolite – artisanal miners recover gold from in-situ weathered rocks using hydraulic methods within two large drainages on the project.
Adularia in veins and vein-selvages, bladed replacement texture, and abundant stibnite (antimony sulfide) occurrences at Cerro Oro suggest a low-sulfidation epithermal gold system. Adularia and bladed textures are widely reported in geologic literature, related to fluid boiling that results in high-grade gold deposition in low sulfidation epithermal veins. Stibnite commonly occurs in a zoned distribution above gold in these veins.
Cerro Oro is 14 km southwest of the Marmato District. Marmato, an epithermal district with a greater than hundred year mining history, is an analog target for Cerro Oro, although Cerro Oro is thought to be exposed at a higher erosional level. Porphyry dacite stocks mapped at Cerro Oro are equivalent to the dacite porphyry hosting the veins at Marmato. At Cerro Oro, it is inferred that gold-bearing fluids flooded into the porous wall rocks from vein structures. Veins may be more robust at depth within competent dacite porphyry, while the porous rocks at surface are important for potential broad zones of lower grade mineralization.
Drilling on two profiles is designed to test several veins and intervening wall rock along a 600 m trend, where veins and country rock have the highest assay values. Both veins, and stockwork and disseminated mineralization will be tested by the same drill holes. The veins extend for approximately 2 km of strike, thus a larger drill program will be needed in the future.
Prism and Miranda are pleased to be drill-testing a low sulfidation epithermal system at Cerro Oro that has the potential for high-grade gold veins within broader zones of lower grade disseminated and fracture controlled mineralization.
Miranda controls approximately 1,100 hectares at Cerro Oro of which 711 hectares are controlled by a contract and the remainder through applications. The project is in the Caldas department 120 km south of Medellin.
