TORONTO, June 09, 2021 (GLOBE NEWSWIRE) -- Gran Colombia Gold Corp. (TSX: GCM, OTCQX: TPRFF) (“Gran Colombia” or the “Company”) announced today multiple high-grade intercepts from the latest 62 diamond drill holes, totaling 13,056 meters, from the 2021 in-mine and near-mine drilling programs and a further 11 diamond drill holes, totaling 3,190 meters, from the 2021 brownfield drilling programs at its Segovia Operations. The Company also announced the assay results from four additional kick-off diamond drill holes (2,319 meters) from the ongoing directional drilling program at the El Silencio Deep Zone.

Significant high-grade intercepts from the latest drill results include:

In-mine

  • Providencia: 211.68 g/t Au and 253.6 g/t Ag over 0.33 meters on the Providencia Vein (PV-ES-008);

  • Sandra K: 147.91 g/t Au and 194.8 g/t Ag over 0.74 meters on the Sandra K Techo Hanging Wall Vein (SK-IU-175);

  • Sandra K: 85.56 g/t Au and 262.1 g/t Ag over 1.32 meters on the Sandra K Techo Vein (SK-IU-169);

  • Chumeca: 187.11 g/t Au and 242.2 g/t Ag over 0.43 meters on the Chumeca Hanging Wall Vein (CH-IU-030);

  • El Silencio: 37.16 g/t Au and 52.5 g/t Ag over 0.55 meters on the 450 Vein (ES-MH08-02);

  • El Silencio: 23.25 g/t Au and 117.5 g/t Ag over 1.80 meters on the Manto Vein (ES-MH08-02);

Brownfield

  • Vera: 15.39 g/t Au and 3,496.1 g/t Ag over 0.70 meters on the Lluvias Vein (VER-ES-010); and,

  • Marmajito: 123.65 g/t Au and 172.60 Ag over 0.93 meters on the Marmajito Vein (MAR-EU-003).

Serafino Iacono, Executive Chairman of Gran Colombia, commented, “Our 2021 in-mine and brownfield drilling programs are continuing to provide us with outstanding results, which confirm the prowess of our Segovia Operations as a world-class high-grade vein system. The Sandra K and El Silencio results continue to impress both in terms of grades and widths and will undoubtedly lead to an important resource growth coupled with a greater flexibility for mining. In addition, a further high-grade result from Vera and an initial high-grade result from the Marmajito vein are shaping up our ongoing brownfield drilling campaign, focused on the other 24 known veins we are not currently mining, as an exciting opportunity to add resources and consequently mine life."

The ongoing 2021 in-mine and near-mine infill and step-out drilling campaigns commenced in early January with four diamond drill rigs operating from purpose-built underground drill stations and comprise a total of approximately 40,000 meters, or about 67% of the total drilling program for this year. In and near-mine in-fill and step-out drilling is focused on replacing the 2021 mining production and organic growth through resource and reserve expansion at the Company’s core operating mines. The other 33% of the planned drilling campaign for 2021 is focused on exploration for new resources in the brownfield exploration targets encompassing the 24 veins within the Segovia mining title that are not currently in production. It commenced in late 2020 at the Vera Project with one diamond drill rig operating from purpose-built surface drill stations. Approximately 33% of the total in-mine and near-mine drilling program for 2021 and 16% of the brownfield exploration drilling program was completed by the end of May.

Gran Colombia currently has 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.

Key Highlights

Providencia

Exploration drilling from underground station PV4940 and surface platform PV4675, installed off the eastern end of the mine workings, delimited by a main dextral strike-slip fault, was completed to test the Providencia Vein close to the fault. Multiple medium to high gold grades were intersected from 13 drill holes (2,929 meters) on an extensional duplex (horsetail splay) where the main Providencia Vein splays into a complex tensional array, with maximum intersection grades of 37.33 g/t Au with 24.2 g/t Ag over 0.55 meters on an interpreted footwall structure of the Providencia Vein (PV-EU-019).

Exploration drilling from surface platform PV6545, aimed at testing the Providencia Vein west of the F Fault, was successfully completed. Multiple high gold grades were intersected in 5 drill holes (2,364 meters) on the main vein system with maximum intersection grades of 211.68 g/t Au with 253.6 g/t Ag over 0.33 meters on the Providencia Vein (PV-ES-008). As a result, Gran Colombia will carry out in-fill drilling in 2021 from a purpose-built underground drill station to better delineate the sparse high-grade intercepts encountered during this initial phase of drilling.

Sandra K

In-mine infill drilling from underground station SK5290, installed off Level 4, has further extend down-plunge, to approximately future Level 9, an ore-shoot outlined by previous drilling, which occurs in a block of the Sandra K vein system delimited by a set of faults striking NE and steeply dipping to the north. This orebody remains open at depth. Multiple high gold grades were intersected from 12 drill holes (1,905 meters) on the main vein system with maximum intersection grades of 147.91 g/t Au with 194.8 g/t Ag over 0.74 meters on the Sandra K Techo Hanging-wall Vein (SK-IU-175). This new orebody offers the potential for another phase of resource growth and the high-grade gold mineralized intercepts encountered so far confirm the higher-grade mineralization at depth.

The ongoing exploration drilling from surface platform SK5050, located in the south fault block of the vein system, is aimed to extend some narrow ore-shoots outlined by previous surface drilling. Drill hole SK-ES-001 returned 8.88 g/t Au with 4.4 g/t Ag over 0.58 meters on the Sandra K Techo Vein.

El Silencio Deep Zone

The ongoing directional drilling program on the El Silencio Deep Zone is targeted to better delineate the southern ore-shoot down-plunge below Level 40, the deepest level of historical mining on the Manto Vein by Frontino Gold Mines (“FGM”). Drilling on the southern ore-shoot continues to be successful in confirming the high-grade nature of the 450 Vein and the down-plunge continuity of the two distinct high-grade domains, previously combined, on the Manto Vein. The 450 Vein, interpreted as a low angle vein or manto, occurs in the hanging-wall of the Nacional Vein, some 40 meters vertically above. Multiple high gold grades were intersected from 4 kick-off holes (2,319 meters) with maximum intersection grades of 37.16 g/t Au with 52.5 g/t Ag over 0.55 meters on the 450 Vein (ES-MH08-02) and 70.56 g/t Au with 289.5 g/t Ag over 0.57 meters on the Manto Vein (ES-MH08-03).

Chumeca

In-mine infill drilling from underground station CH5110, installed off Level 2, aimed to extend a cluster of potential ore-shoots outlined by mining within the upper levels of the past operation, was completed. Multiple medium to high gold grades were intersected from 20 drill holes (2,041 meters) on the main vein system, which identified two distinct structures named as the Chumeca hanging-wall and footwall veins interpreted as a split of the main Chumeca Vein, with maximum intersection grades of 187.11 g/t Au with 242.2 g/t Ag over 0.43 meters on the hangingwall structure (CH-IU-030) and 15.90 g/t Au with 20.5 g/t Ag over 0.56 meters on the footwall structure (CH-IU-032).

Vera

Exploration drilling from surface station VER5340 confirmed the continuity of the high-grade gold and silver mineralization in the upthrown fault block, below the deepest level of the historical mine. A bonanza silver grade coupled with a high gold grade was intersected in drill hole VER-ES-010, one of the latest 7 drill holes (2,140 meters) completed on the main vein system, with maximum intersection grades of 31.78 g/t Au with 8,150.00 g/t Ag over 0.30 meters on the Lluvias Vein.

Marmajito

The ongoing brownfield exploration drilling program commenced in February 2021 with one diamond drill rig operating from the underground drill station PV5630, installed off Level 16 of the Providencia mine. This drilling program is aimed at exploring the down-dip extension of the historical Marmajito Vein that was operated by FGM until 2000. FGM developed the mine on 18 levels, the longest (Level 4) being approximately 800 meters. Historical records of FGM report reserves of 232,000 t grading 18 g/t Au. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and the Company is not treating the historical estimate as current mineral resources or mineral reserves. Gold mineralization at Marmajito is contained predominantly within a N40-50°W trending massive white quartz vein dipping moderately (35-45°) to the north, averaging 0.33 m in width, hosted by granodiorite. The Marmajito Vein occurs in the hanging-wall of the Providencia Vein, some 100-150 meters vertically above The style of mineralization is characterized by narrow veins hosting two main stages of mineralization: “Stage 1” is represented by milky quartz, disseminated pyrite and sphalerite, while “Stage 2” is characterized by grey quartz and banded pyrite intergrown with galena. A total of 4 drill holes totaling 1,050 meters) have been completed so far at Marmajito, with maximum intersection grades of 123.65 g/t Au with 172.6 g/t Ag over 0.93 meters on the Marmajito Vein.
