(MENAFN- Newsfile Corp)
Yerington, Nevada--(Newsfile Corp. - August 21, 2024) - Lion Copper and Gold Corp. (TSXV: LEO) (OTCQB: LCGMF) (" Lion CG " or the " Company ") today released results from its Bear deposit 2024 exploration drilling program in the Yerington District of Nevada. As a second phase of drilling subsequent to the exploration drilling in 2023 (see Oct 27, 2023, news release ), an additional US$1,500,000 (total US$4,000,000) was funded as early advance of the Stage 3 funding for exploration under the Company's agreement with Nuton LLC, a Rio Tinto venture (see December 22, 2023, new release ).
Bear Deposit 2024 Drilling Highlights
Diamond core drill hole B-056A encountered 2,376 ft of 0.40% TCu, including 130 ft of 0.65% TCu and 138 ft of 0.62% TCu collared midway between legacy Anaconda drill holes B-014 and B-022 Diamond core drill hole B-055, collared 2,750 ft southwest from drill hole B-054, encountered weak copper mineralization along the far western edge of the known deposit
B-056A is a deep, angle drill hole located along a northwest trend of elevated copper grades defined by legacy Anaconda drilling. Drill hole B-055 is coincident with a strong Induced Polarization (IP) anomaly identified during the recent IP survey completed in late 2023. B-056A returned a significant drill intercept of 0.40% TCu over 2,376 ft from a depth of 1,237 ft and ending in final two intervals of 1.150 TCu% and 0.904 TCu%. Figure 1 shows the location of Bear drill holes and Figure 2 shows a cross section through drillhole B-056A.
Steven Dischler, Lion CG's CEO, states, "The thick intervals of copper mineralization encountered in our latest drilling of B-056A highlights the tremendous size and potential of the Bear deposit. The wide intercepts of copper mineralization throughout the Bear porphyry system are encouraging and continue to support our fundamental view that continued systematic exploration has potential to unlock substantial new zones of high-grade copper mineralization and further expand and upgrade the footprint of the deposit."
Bear Deposit 2024 Drilling Details
Two diamond core drill holes, B-055 and B-056A were angle drilled to depths of 3,435 ft and 3,613 ft, respectively. Following the 2023 drilling, an IP/resistivity survey was completed that identified the strongest IP anomaly in the Company and Anaconda archives that is known in the Bear deposit area. B-055, drilled on the far western edge of known mineralization, was directed to intersect this very strong and thick 40 to +55 milliradian IP anomaly ( see Figure 3 ). B-055 cut several narrow zones of weak copper mineralization within a thick 2,330 ft intercept of sulfide mineralization from a depth of 1,105 ft. The drill intercept of sulfide mineralization coincides with the IP anomaly, although the 2% sulfide is lower than predicted by the IP anomaly. The source of the IP anomaly is unconfirmed with drilling; however, this may represent the high pyrite cap of the Bear deposit and remains subject to consideration for future exploration.
B-056A was drilled to test a wide spaced drilling gap along the northwest mineralization trend identified previously by Anaconda legacy and SPS 2023 drill holes. B-056A returned a significant drill intercept of 0.40% TCu over 2,376 ft from a depth of 1,237 ft. The final two intervals of B-056A ended in grades of 1.150 TCu% and 0.904 TCu%. Drill hole B-056 was abandoned at depth due to borehole collapse in high grade copper. A total of 16 sample intervals reported values between 1.01 to 2.09 TCu%. Four drill intervals, for a combined length of 23.5 ft, had no sample recovery adjacent to these high-grade intervals.
B-056A is the 2nd best grade-thickness intercept made to date at Bear and attests to the strength and scale of the mineralization (Table 1 and Table 2). Quartz-chalcopyrite veining is the dominant form of sulfide mineralization, with quartz vein percentages ranging from 1% to 5%. Within these zones, potassic alteration is dominant, defined by abundant secondary biotite and lesser potassium feldspar flooding. Veining typically dips 40-50° to the north northeast and correlates closely with quartz monzonite porphyry dikes also having typical 40-50° north northeast dips as determined by oriented core measurements. The presence of the large grade-thickness intercept, the potassic alteration, and quartz veining percentages are interpreted to indicate B-056A may occur near the core of the deposit. Figure 2 shows the results of B-056A in relation to previous drilling along a north-south Section 1.
The size and strength of mineralization in the Bear deposit is highly permissive for further exploration given the exceptionally large footprint of the known mineralization, multiple 1-2% TCu intervals within thick mineralized zones, and current widely spaced drilling at 500-to-1,000-foot intervals. In the central zone where B-022, B-056A, and B-006 and the highest grade-thickness values are located, exploration drill tests are compelling in locations along the west-northwest identified strike as well as up-dip and down-dip following the quartz monzonite porphyry dikes.
Background of the Bear Deposit
The Bear deposit is a large and partially defined porphyry copper exploration target located primarily on private lands approximately 3 miles north of Anaconda's former Yerington open pit and 2.6 miles southeast of the MacArthur open pit, in Lyon County, Nevada. The Bear deposit was previously jointly held by The Anaconda Copper Mining Company ("Anaconda"), one of the largest copper mining companies of the 20th century, and Phelps Dodge Corporation ("Phelps Dodge", now Freeport-McMoRan). Lion CG, through its wholly owned subsidiary Singatse Peak Services, LLC ("SPS"), is the first company to consolidate the property through private land option agreements and controls a land position of approximately 2,330 acres over the Bear deposit.
The Bear deposit was first identified by Anaconda in 1961 and has a long history of drilling development including Anaconda (1961-1967), Phelps Dodge (1969-1973), and a SPS program funded by Freeport Nevada LLC (2015-2016). Drilling by Anaconda, Phelps Dodge, and SPS all intersected zones of copper mineralization ranging from 490 ft to 2,843 ft thick (Table 1). In 2023, SPS angle drilled B-053A and B-054 northwest along the mineralization trend previously identified by Anaconda legacy drill holes (Figure 1). For additional details on the drilling background of the Bear deposit please see October 27, 2023, news release.
The Bear deposit has a similar regional geologic setting to other Jurassic-aged porphyry-style copper deposits in the Yerington district, including the Yerington mine, MacArthur, and Mason deposits. The Yerington mine was operated by Anaconda from 1951 through 1978, extracting 1,744,237,000 lbs. of copper.
The footprint of the Bear deposit extends 2.5 miles (4 km) in length in a northwest-southeast direction and 1.7 miles (2.7 km) in length in the northeast-southwest direction (Figure 1). Mineralization at the Bear is concealed under approximately 200 to 1,200 ft of post-mineral alluvial and Tertiary volcanic cover.
Results of angled drill hole B-053A, B-054, and B-056A demonstrate the structural control and orientation of the mineralized zones. The quartz monzonite porphyry dikes and associated mineralization strike roughly east-west to northwest-southeast with a northerly dip as shown in the cross-section (Figure 2). Mineralization at the Bear is interpreted to include a first pulse associated with the intrusion of quartz monzonite into the granodiorite and characterized as calc-silicate alteration along the contact of the older host rocks of granodiorite and younger quartz monzonite. A second pulse of mineralization is represented, where quartz monzonite porphyry dikes intrude into the quartz monzonite and mineralized veins formed in zones in and along the margins of the porphyry dikes. The main copper sulfide mineral is chalcopyrite, with lesser bornite which typically occur within veins and as disseminations. The zones of primary sulfide mineralization remain open in several directions where the limits of mineralization are not closed off by drilling. No zones of oxide mineralization or supergene enrichment have been identified at the Bear deposit.
Quality Assurance & Control
All samples were collected via diamond core drilling by Alford Drilling, LLC (of no relation to Tony Alford, a director of the Company) of Elko, NV. Core samples were sawed on the Yerington Property site by Company personnel. All samples were picked up by Skyline Assayers & Laboratories ("Skyline"), Tucson, AZ and transferred for crushing, splitting, and pulverizing sample preparation. Multi-element (47 el.) analyses were completed using a multi-acid digestion and ICP OES/ICP-MS finish (Skyline's TE-5 method). Commercially prepared certified reference materials and blanks were inserted by the Company at 50-ft intervals to ensure precision of results as a quality control measure. The Company also applied a chain of custody program to confirm sample security during all stages of sample collection, shipment, and storage.
