Serafino Iacono, Executive Chairman of GCM Mining, commented
,
“We completed a very robust exploration campaign at our Segovia Operations in 2021 with a total of approximately 97,000 meters completed in 444 diamond drill holes at our producing mines and our high-priority brownfield targets. These drill results will be incorporated in the annual mineral reserve and resource updates that are expected to be announced later this month. Our Segovia Operations continue to demonstrate their prowess as a world-class system, both in terms of its size and high grades, as shown by the continued outstanding results from the 2021 drilling programs. The team’s exploration model and understanding of the local vein systems led to the discovery of the 1040 Vein at the El Silencio Mine in 2021 which has the potential to add substantial resources and increase the mine life for this operation. Drilling from surface at the Sandra K Mine has proven the down-plunge extension of the main ore-shoots to well below the deepest level of the mine, as well as a further strike extension of the main vein system to the north by 150 meters. In addition, brownfield drilling on the Marmajito Vein has shown multiple high-grade intersections, which reinforce the exploitation potential of this vein by taking advantage of the proximity of the Providencia Mine’s infrastructure. For 2022, we have committed to contining our exploration campaign at Segovia with another 91,000 meters of drilling at our producing mines and high-priority brownfield targets.”
The 2021 in-mine and near-mine infill and step-out drilling programs commenced in January 2021 and focused on replacing the 2021 mine production and on organic growth through resource and reserve expansion at the Company’s core operating mines. GCM Mining completed a total of 184 drill holes in 2021 totaling 47,735 meters which represented about 119% of plan. The in-mine and near-mine drilling campaign was complemented by another 196 diamond drill holes totaling 33,471 meters that were completed in 2021 in an ongoing underground in-fill drilling campaign carried out by the Company’s Mine Geology Department, primarily at the El Silencio Mine, which focused on resource definition within the underground mine developments.
The 2021 brownfield drilling campaign, which focused on exploration for new resources at the brownfield exploration targets on the 24 veins within the Segovia mining title that are not currently in production, commenced in late 2020 at the Vera Project. The 2021 brownfield exploration drilling campaign was finalized at the end of December 2021 with a total of 64 drill holes totaling 15,924 meters, about 20% less than planned mainly due to the lengthy administrative processes involved to obtain permission to access the land where the drilling platforms were built.
GCM Mining’s 2022 diamond drilling campaign will comprise approximately 91,000 meters with up to 52,000 meters of in-mine and near-mine drilling and 15,000 meters of underground in-fill drilling at its four producing mines together with 24,000 meters of brownfield drilling at its high-priority targets within the other 24 known veins it is not currently mining in its Segovia mining title.
GCM Mining currently has a total of 13 diamond drill rigs in operation at Segovia as follows:
In-mine and near-mine drilling
- Three rigs are carrying out resource definition in the Sandra K Mine from two purpose-built surface platforms and one underground drill station in the Sandra K Mine; and,
- Two rigs are carrying out resource definition on the El Silencio Deep Zone from a purpose-built underground drill station in the El Silencio Mine to test the 450 Vein from the Lejanias sector, and from a purpose-built underground drill station on Level 3 of the Sandra K Mine conducting directional infill drilling on the southern ore-shoot below Level 38.
Underground In-fill drilling
- Three rigs at El Silencio; and
- One rig at Sandra K.
Brownfield drilling
- Two rigs are operating from surface on the La Guarida-Cristales Trend;
- One rig is operating from an exploration ramp starting from Level 15 of the Providencia Mine testing the Marmajito Vein; and
-
One rig is operating from surface at Vera testing the northeastern extension of the vein system and a soil silver anomaly.
Key Highlights
IN-MINE and NEAR-MINE DRILLING
Sandra K
In-mine infill drilling from underground station SK5680, installed off Level 6, was still ongoing at the end of 2021. This program has further extended down-plunge, to approximately future Level 9, an ore-shoot outlined by previous drilling, which occurs in the northern fault block of the Sandra K Vein System delimited by a set of faults striking NE and steeply dipping to the north related to the Lejanias Fault System. This ore-shoot remains open at depth. Multiple high gold grades were intersected in 12 drill holes (total of 1,747 meters) on the main vein system with maximum intersection grades of
159.88 g/t Au with 248.0 g/t Ag over 0.30 meters
on the Sandra K Techo Vein (SK-IU-200). The high-grade gold mineralized intercepts encountered confirm the higher-grade mineralization at depth.
Surface exploration drilling from platform SK6020, located in the northern fault block of the main vein system, was still ongoing at the end of 2021. This program was designed on a 150 m x 150 m drill spacing and was aimed to extend down-dip the main vein system from future Level 9 to Level 15 and along strike. Drilling was successful in extending the main vein system along strike by 150 meters and down-dip. Medium to high gold grades were intersected from 7 drill holes (total of 3,477 meters) on the main vein system with maximum intersection grades of
40.39 g/t Au with 42.4 g/t Ag over 0.41 meters
on the Sandra K Techo Vein (SK-ES-027).
El Silencio
In-mine exploration drilling from underground station ES4170, installed off Level 15 of the Providencia mine, was designed on a 125 m x 125 m drill spacing to test the continuity of the Nacional Vein from future Level 40 to Level 42 in the southernmost sector of El Silencio Mine. Drilling was successful in demonstrating continuity together with high grades. Medium to high gold grades were intersected from 3 drill holes (total of 610 meters) with maximum intersection grades of
38.41 g/t Au with 28.6 g/t Ag over 0.68 meters
(ES-EU-028A).
Additional in-mine exploration drilling from underground station ES5110, installed on Level 38, was completed. The aim of this program was to confirm the extension of the 450 Vein close to the mine workings on the Nacional Vein. The 450 Vein, discovered by directional drilling in 2020, is interpreted as a low angle vein or manto that occurs in the hanging-wall of the Nacional Vein, some 40 meters vertically above. Drilling was successful in demonstrating the extension as well as high grades. Multiple high gold grades were intersected from 9 drill holes (total of 1,236 meters) with maximum intersection grades of
50.77 g/t Au with 79.4 g/t Ag over 0.55 meters
(ES-EU-037).
The ongoing directional drilling program on the El Silencio Deep Zone is targeted to extend and better delineate the southern ore-shoot down-plunge below Level 40, the deepest level of historical mining on the Manto Vein. Drilling on the southern ore-shoot continues to be successful in confirming the high-grade nature of the Nacional and Manto veins and extending the down-plunge continuity of the southern of the two distinct high-grade domains, previously combined, on the Manto Vein by 170 meters. A high gold grade intercept was intersected from kick-off hole ES-MH08-13 (540 meters) with maximum intersection grades of
236.44 g/t Au with 123.0 g/t Ag over 0.60 meters
on the Nacional Vein.
Carla
Infill drilling from platform CA4850 was designed to test the La Gran Colombia Vein System in the Carla Mine further down-dip to correlate the intersections from this follow up phase of drilling with some high-grade intercepts encountered in the 2020 drilling phase. To date, it is still difficult to correlate the high-grade intercepts with the main structures of the La Gran Colombia Vein System interpreted so far that comprises: the La Gran Colombia Vein (“LGC”), which is a northerly-trending master vein with a continuous strike of more than 700 meters that has been drilled to a vertical depth of about 250 meters, on which the current mining operation is being developed at a shallow depth, and an hanging-wall vein (“LGC-HW”) that strikes and dips sub-parallel and in close proximity to the LGC, which merges into the LGC or dies out at depth. A high gold grade was intersected from hole CA-ES-036 (398 meters) with maximum intersection grades of
254.30 g/t Au with 316.7 g/t Ag over 0.45 meters
on the La Gran Colombia Vein.
BROWNFIELD DRILLING
Marmajito
The brownfield exploration drilling program on the Marmajito Vein, which commenced in February 2021 with one diamond drill rig operating from underground drill station PV5630, installed on the exploration ramp that starts from Level 15 of the Providencia mine and leads to the western extension of the Marmajito mine workings, moved to drill station MAR5380, installed off the same exploration ramp. This program was aimed to follow up a high-grade intercept encountered by drilling from drill station PV5630. Drilling was successful in extending the vein down-dip by 250 meters. Multiple high gold grades were intersected from 3 drill holes (918 meters) with maximum intersection grades of
131.10 g/t Au with 294.3 g/t Ag over 0.32 meters
on the Marmajito Vein (MAR-EU-015).
La Guarida-Cristales Trend
This surface exploration drilling program, which commenced in August 2021 with one diamond drill rig initially operating from drill platform CR6640, moved to drill platform CR6700 to test the down-plunge extension of the La Guarida Mine ore-shoot delimited by two NW trending faults. Two drill holes, totaling 455 meters, were completed with maximum intersection grades of
5.42 g/t Au with 21.0 g/t Ag over 0.42 meters
on the La Guarida Vein (CR-EU-018).
Surface exploration drilling continued from drill platform CR6940 with 4 drill holes, totaling 630 meters, designed to test the northeastern extension of the La Guarida Vein beyond the known ore-shoot. Drill hole CR-ES-031A was successful in intersecting two veins corresponding to La Guarida Vein and the SW extension of the Cristales Vein, which occurs in the footwall of the La Guarida Vein, with maximum intersection grades of
5.07 g/t Au with 5.2 g/t Ag over 0.31 meters
on the La Guarida Vein and
8.24 g/t Au with 13.3 g/t Ag over 0.37 meters
on the Cristales Vein (CR-EU-031A).
Surface exploration drilling from drill platform CR6850 was designed to start testing the extension of the Cristales Vein between the La Guarida and Cristales mines. A total of 5 drill holes, totaling 1,220 meters, were completed with maximum intersection grades of
18.52 g/t Au with 24.9 g/t Ag over 0.68 meters
on the Cristales Vein (CR-EU-024).
Additional surface exploration drilling was designed from drill platform CR7370 aimed to test the down-plunge extension of the ore-shoot at the northeast-most end of the Cristales Mine. A total of 7 drill holes, totaling 1,814 meters, were completed with maximum intersection grades of
56.88 g/t Au with 41.0 g/t Ag over 0.39 meters
on an unknown vein that occurs in the hanging-wall of the Cristales Vein (CR-EU-025).
The following table lists the key intercepts from the final 2021 in-mine, near-mine and brownfield drilling programs that were received since the press release issued on December 16, 2021.
