With oriented core drill packages at Tibbs and Seventymile North of 60 Mining Information – June 11, 2021
After elevating C$3.5 million in Might, Tectonic Metals Inc. is gearing up for the beginning of its 2021 exploration in Alaska, which might be anchored by oriented core drill packages at its Tibbs and Seventymile gold tasks.
“It is time! The outdated saying, ‘When you’re not drilling, you are not discovering gold’ couldn’t be extra becoming proper now for Tectonic,” mentioned Tectonic Metals President and CEO Tony Reda. “Our current capital elevate introduced in further subtle shareholders to assist us in our reason behind discovering extra gold this summer season by the execution of diamond drill campaigns on two distinctive tasks, Tibbs and Seventymile.”
Tectonic has had success discovering gold at these ignored Inside Alaska tasks since its formation in 2018.
This included reconnaissance stage exploration throughout its Alaska gold tasks throughout 2019 and extra superior exploration and rotary air blast drilling at Tibbs and Seventymile final 12 months. These packages helped refine targets for this 12 months’s deliberate 4,800 meters of oriented drilling, which is able to present important info on structural and geological orientation at each tasks.
This work is slated to start out with drilling at Tibbs subsequent week after which at Seventymile later in the summertime.
Pogo-like gold at Tibbs
Tectonic’s Alaska gold exploration success contains the invention of high-grade mineralized buildings at Tibbs, a 13,480-acre exploration challenge about 22 miles (35 kilometers) southeast of Northern Star Resources Ltd.’s high-grade Pogo gold mine in Alaska’s Goodpaster Mining District.
Throughout its 2019 exploration program at Tibbs, Tectonic reduce 29 meters averaging 6.03 grams per metric ton gold at Michigan, a beforehand recognized however underexplored zone on the property.
Highlights from 11 rotary air blast holes drilled at Michigan in the course of the 2020 Tibbs exploration program embrace 9.1 meters averaging 6.71 g/t gold, 12.9 meters averaging 2.61 g/t gold, and seven.6 meters averaging 3.73 g/t gold.
The remaining 16 RAB holes of the 2020 Tibbs drill program targeted on Decrease Trench and Wolverine, adjoining zones alongside a 3,000-meter potential hall that additionally encompasses Michigan.
Tectonic stories that drilling at Decrease Trench encountered gold mineralization an identical to Michigan however 1,500 meters to the northwest, indicating a major hydrothermal system throughout the bigger structural hall.
The most effective intercept at Decrease Trench is 7.6 meters averaging 4.5 g/t gold, together with 3.05 meters averaging 10.78 g/t gold in gap TBRB20-032.
Tectonic’s 2021 exploration marketing campaign at Tibbs will encompass two phases of oriented diamond drilling separated by a TITAN-24 geophysical survey.
The preliminary part of 2021 drilling is designed to validate and develop upon identified high-grade gold exploration targets similar to Michigan and check newly recognized structural and soil geochemical targets delineated by Tectonic in 2020.
The second part of drilling will check targets generated by the TITAN survey, which might be targeted on figuring out low-angle buildings related to those who carry a lot of the high-grade gold ore at Pogo throughout the unexplored gneissic rocks within the western portion of Tibbs.
Mapping carried out on this space final 12 months recognized low-angle faults inside reasonably dipping gneissic rocks, that are key traits of the Pogo geological mannequin.
Soil sampling at 5 grids over gneissic rocks west of the Wolverine zone within the north and the Grey Lead zone within the south recognized a number of gold-in-soil anomalies with the very same geochemistry as mineralization noticed at Pogo, together with a 2,500-meter-long gold-arsenic anomaly about 500 meters northwest of Grey Lead, the place previous drilling has tapped high-grade gold in steeply dipping veins.
Highlights from historic drilling at Grey Lead embrace: 5.7 meters of 19.14 g/t gold; 5.3 meters of 15.76 g/t gold; and 4.3 meters of 6.13 g/t gold.
The targets of the 2021 Tibbs exploration program are anticipated to incorporate:
Michigan – Drilling will give attention to each figuring out controls on high-grade gold mineralization by oriented core drilling and stepping out to the southwest alongside the interpreted development of the northeast-trending Michigan construction that has to date been traced for about 275 meters alongside strike.
West Trench – A high-tenor gold-in-soil anomaly with coincident arsenic, bismuth, and tungsten was found final 12 months in gneissic rocks reduce by a mapped diorite dike about 1,200 meters west of the Decrease Trench zone. This 12 months’s work at West Trench would be the first time the gneissic rocks internet hosting this strong gold-in-soil anomaly have been drilled.
Wolverine – Regardless of being the positioning of the biggest gold-in-soil anomaly at Tibbs, earlier drilling at Wolverine was unable to clarify the supply of the high-tenor gold in soils recognized at this roughly 800- by 1,000-meter prospect. Tectonic now goals to drill a newly recognized and untested east-west trending construction at Wolverine.
Johnson Saddle – Excessive-grade soil and rock anomalies, together with a 5.9 g/t gold rock pattern with related bismuth and tungsten uncovered in Tectonic’s 2018 trenching program, have been recognized at this prospect. This 12 months’s drilling will additional check Tectonic’s speculation that the Johnson Saddle prospect is located at a distinguished intersection zone of northeast-trending buildings discovered inside and adjoining to potential gneissic rocks on a mapped low angle thrust fault.
Grey Lead – Oriented diamond drilling will assist decide structural controls and continuity on the high-grade, 275-meter-long Grey Lead together with step-out drilling to the northeast on the close by Hilltop-Oscar goal space. Grey Lead hosts Pogo-style quartz veins and is open alongside strike and at depth. Drilling by a earlier operator solely reached a depth of 120 meters. Tectonic will search to find out whether or not the Grey Lead vein is offset to the east past the boundaries of historic drilling.
Thrilling Seventymile targets
Tectonic will even be finishing up oriented diamond drilling at Seventymile, a roughly 150,000-acre land bundle between two prolific placer gold mining districts – Yukon’s Klondike to the east and Alaska’s Circle Mining District to the west.
Though exploration carried out twenty years in the past demonstrated the potential for a number of gold deposits throughout this district-scale land bundle, robust market situations reduce brief previous packages earlier than this prospectivity might be totally realized.
Whereas gold has been recognized throughout the breadth of Seventymile, a lot of the work by Tectonic and former explorers has targeted on the 8,000-meter-long Flume development.
Earlier drilling at Flanders, a 1,500-meter-long goal inside Flume, has encountered grades as excessive as 187.9 g/t gold over 1.1 meters. About 5,000 meters northeast of Flanders, within the Bonanza zone, one historic gap reduce 44.2 meters of 1.34 g/t gold.
With new geological concepts, Tectonic carried out early staged exploration at Seventymile in the course of the 2018 and 2019 subject seasons in preparation for an preliminary 26-hole RAB drill program focusing on six extremely potential top-of-bedrock gold targets alongside the Flume development – Flanders, East Flanders, Deep Creek, Bonanza Creek, and Flume-Bonanza Hyperlink.
Highlights from this drilling embrace: 19.81 meters averaging 1.37 g/t gold at Bonanza; 6.1 meters averaging 2.07 g/t gold within the beforehand undrilled Flume-Bonanza connector zone; and 4.57 meters averaging 1.2 g/t gold in a beforehand unrecognized construction south of Flanders.
Tectonic says its exploration at Seventymile has each validated and confirmed continuity of the mineralized buildings throughout the Flume development.
This 12 months’s drilling will give attention to acquiring detailed structural and geological info whereas testing for growth potential, grade, and scale at every goal.
The deliberate targets for the 2021 program at Seventymile are:
Flanders – Excessive-grade, north-dipping quartz pressure veins hosted by a particular iron-rich basalt are open for growth to the northwest, east, southeast, and at depth, and high-grade gold mineralization encountered by historic drilling is open at depth and alongside strike.
Flume – Drilling will check the down-dip extent of identified shear-hosted gold mineralization beforehand encountered at this goal, in addition to step-out drilling to check the interpreted continuation of the construction in an space of high-tenor gold-in-soil anomalies east of Flume Creek.
Bonanza – Drilling will intention to acquire structural context for the gold mineralization beforehand recognized there, in addition to stepping out from a 2020 RAB gap that reduce 1.37 g/t gold over 19.81 meters.
Flume-Bonanza – Tectonic solely drilled one RAB gap on the 800-meter-long Flume-Bonanza gold-in-soil anomaly, which reduce the 6.1 meters of two.07 g/t gold highlighted above. This 12 months’s drilling will check the construction alongside its extent and procure the first-ever diamond core from the goal space.
Alder – Present in the identical iron-rich basalt as noticed on the Flanders goal, Alder hosts strong gold-in-soil anomalies with grades as excessive as 2.34 g/t. Drilling will give attention to stepping west of historic drilling into the basalt.
“To say that we’re enthusiastic about this 12 months’s packages can be an understatement!” mentioned Reda. “From structural research to reinterpreting geophysical surveys to relogging historic core to in-depth geochemistry, soil, rock, RAB chip and drill core evaluation to 3D modeling, we’ve left no stone unturned to offer us with one of the best geological understanding of our drill targets.”
