$Gran Colombia Gold Provides Exploration Update for Its Segovia Operations February 23, 2021
$Announces multiple high-grade gold and silver intercepts from the initial drill holes at its Vera brownfield target
Plans to drill 60,000 meters at its Segovia Operations in 2021 at an estimated total cost of approximately US$14 million TORONTO, Feb. 23, 2021 (GLOBE NEWSWIRE) --
$Gran Colombia Gold Corp. (TSX: GCM, OTCQX: TPRFF) announced today that the first eight step-out diamond drill holes at the Vera brownfield target in its Segovia mining title have resulted in multiple high-grade gold and silver intercepts, including:
96.68 g/t Au and 423.7 g/t Ag over 0.49 meters on the Lluvias Vein m(VER-ES-006);
46.54 g/t Au and 365.0 g/t Ag over 0.34 meters on the Lluvias Vein (VER-ES-005); and
5.48 g/t Au and 212.1 g/t Ag over 0.64 meters on the Lluvias Vein (VER-ES-003).
The diamond drill holes at Vera, totaling 2,223 meters, were carried out from surface as part of the Company’s brownfield drilling program which commenced in October 2020 aimed at testing the down-dip continuity of the historical Vera mine, a past-producing mine operated by Frontino Gold Mines Ltd (“FGM”) from 1940 until 1988.
The Vera vein is one of 24 known veins in the Segovia mining title that Gran Colombia is not currently mining.
Serafino Iacono, Executive Chairman of Gran Colombia, commented, “We are very encouraged by these early drilling results at Vera which provide a clear indication that mineralization is still open at depth.
This is a very exciting time for Gran Colombia, as we continue to explore our high-grade producing mines and expand our exploration efforts to include regional brownfield targets.
The exploration team has done an outstanding job over the last several years as we have continued to replace and replenish our resource base and reserves at our mines.
Now the team is ready to take on a strategic, expanded brownfield exploration program, targeting new resources that will utilize our current infrastructure and capacity, leading to production growth and mine life extension at Segovia. We are confident that our exploration campaign will continue to be a key value driver for Gran Colombia as we move forward.”
Key Highlights of the Vera Drill Program
The Vera brownfield target is located east of the Sandra K – Cogote Vein System and represents one of the highest priority targets in the Company’s brownfield drilling program at Segovia.
Following a 3D geological and structural modelling exercise incorporating a compilation of old channel sampling and mining data along with a new detailed geological-structural survey, an initial diamond drilling program totaling 3,500 meters in twelve holes was designed for the Vera brownfield target.
This is aimed at testing the down-plunge continuity of the main orebody mined in the past and the extension of a potential NE plunging ore-shoot occurring in the southern sector of the historical mine, currently being mined by artisanal miners under contract with the Company.
The brownfield drilling program at Vera commenced in early October 2020 with one diamond drill rig operating from two purpose-built surface drill stations.
Approximately 63% of the total drilling program was completed by the end of January in the eight drill holes reported in this press release.
The remaining four drill holes (approximately 1,300 m) will be completed by the end of March 2021.
Drilling has confirmed a new model for the Vera vein which was built based on historical drill hole intercepts, new structural data, chip channel data and fieldwork.
This new model incorporates a post-mineralization NW striking dextral oblique-reverse fault that dips to the NE.
This was not previously identified by FGM, which interpreted that there were two sub-parallel quartz veins named Vera and Lluvias, the latter in the hanging-wall of the Vera vein.
The intersections to date of the current drill program confirm the presence of the interpreted fault and the relative displacement along it, and support the model that the Vera and Lluvias veins are the same vein, with the Lluvias vein occurring in the upthrown fault block.
Gran Colombia’s drilling program was successful in confirming the continuity of the high-grade gold and silver mineralization in the upthrown fault block, below the deepest level of the historical mine.
The presence of high silver grades at Vera confirms the metal zoning pattern and polarity that characterize the entire eastern sector of the Segovia RPP-140 mining title, shown by a reversal of the Au/Ag ratios from Sandra K to Guia Antigua.
The style of mineralization of the intersections drilled so far is characterized by narrow veins hosting two main stages of mineralization.
“Stage 1” is represented by milky quartz and pyrite and galena forming nests, while
“Stage 2” is characterized by grey quartz and pyrite intergrown with galena and sphalerite along with minor amounts of silver sulfosalts (possibly proustite and/or pyrargyrite).
The veins are enveloped by a narrow halo of sericitic alteration. The table below lists the key intercepts from the Vera drilling program:
