Gran Colombia Gold Finds Two More High-Grade Veins At El Silencio Mine In Segovia

Gran Colombia Gold Corp. (TSX: GCM, OTCQX: TPRFF) has discovered high-grade intercepts from the first 59 diamond drill holes totaling 10,229 meters of an in-fill drilling campaign that is being carried out by the company’s mine geology department at the El Silencio mine at its Segovia Operations. This 23,000 meter drilling campaign, which commenced in 2020 and will be completed this year, is focused on resource definition within the underground mine developments of the El Silencio mine and complements the previously announced 60,000 meter drilling program being carried out in 2021 by the company’s exploration team. High-grade intercepts from two new veins recently discovered by this in-fill drilling campaign at the El Silencio mine provide and corroborate information of importance for the current and future development of different sectors of this flagship mine.

The best high-grade intercepts from these latest drill results at the El Silencio mine include:

• 1040 Vein, new discovery: 137.44 g/t Au and 10.1 g/t Ag over 0.56 meters (ES-GM-U51-20);
• 1150 Vein, new discovery: 93.19 g/t Au and <0.3 g/t Ag over 0.54 meters (ES-GM-U59-20);
• 1180 Vein: 73.03 g/t Au and 32.0 g/t Ag over 0.30 meters (ES-GM-U49-20); and
• Manto Vein: 44.49 g/t Au and 98.5 g/t Ag over 0.35 meters (ES-GM-U17-21)

Serafino Iacono, Executive Chairman of Gran Colombia, said: “Our drilling programs in Segovia are continuing to provide us with outstanding results. With the discovery of two additional high-grade veins at the El Silencio mine, close to the mine workings currently in production, we remain confident that we will continue to expand mineral resources and add to the mine life for this operation. These new discoveries are further evidence that our main mines remain under-explored and have the potential to be larger than what we understand today.”

Gran Colombia’s mine geology department currently has three diamond drill rigs in operation at Segovia carrying out resource definition within the underground developments of the El Silencio mine in a program that has another 13,000 meters of drilling to be completed this year. In addition, as outlined in the company’s press release dated June 9, 2021, the company has another seven diamond drill rigs in operation at Segovia, with three rigs carrying out resource definition on the Sandra K mine from two purpose-built surface platforms and one underground drill station within the underground developments of the Sandra K mine; one rig operating from Level 3 of the Sandra K mine targeting the down-plunge extension of the south ore-shoot of the El Silencio mine; one rig operating from surface at Providencia exploring the westernmost end of the Providencia vein system; one rig operating from the deepest underground developments of the Providencia mine exploring the down-dip extension of the Marmajito Vein; and one rig operating from surface at Carla to follow-up the high-grade intercepts encountered at depth during the last drilling campaign.
