Vancouver, British Columbia--(Newsfile Corp. - October 27, 2023) - Lion Copper and Gold Corp. (TSXV: LEO) (OTCQB: LCGMF) ("Lion CG" or the "Company") today released assay results from its 2023 exploration program in the Yerington District of Nevada. This exploration program was funded by a US$2,500,000 early advance of Stage 3 funding under the Company's agreement with Nuton LLC, a Rio Tinto venture (see February 10, 2023 news release).

Five targets were drilled (Figure 1) with the most compelling results produced at the Bear deposit, a large and partially-defined zone of porphyry copper mineralization, located almost entirely on private lands and concealed beneath a thick fault slice of younger Tertiary ignimbrites and alluvial cover. The Bear deposit was previously jointly held by 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), with Lion CG having subsequently consolidated the Bear deposit by way of multiple private landowner lease and purchase option agreements.

Bear Deposit 2023 Drilling Highlights (Figure 2, Table 1):

  • Diamond core drill hole B-053A encountered 926 ft of 0.31% TCu, including 233 ft of 0.47% TCu, collared 925 ft northwest of legacy Anaconda drill hole B-014
  • Diamond core drill hole B-054 encountered 1,048 ft of 0.26% TCu, including 131 ft of 0.50% TCu, collared 925 ft northwest from B-053A

These deep angle drill holes were located along a northwest projection of elevated copper grades defined by legacy Anaconda drilling and a coincident magnetic low and strong Induced Polarization (IP) anomaly, both of which are recognized trends in the Yerington District. Information gained from this recent drilling not only expands the size of the Bear deposit but also highlights additional targets which remain untested.

Travis Naugle, Lion CG's CEO, states, "The thick intervals of copper mineralization encountered in our latest drilling continue to showcase the immense size and potential of the Bear deposit. With mineralized intercepts expanding over 1,800 feet from previously known mineralization, we have only begun to touch on the boundaries of this expansive porphyry system that covers more than three square miles. Despite historic drilling by major miners like Phelps Dodge and Anaconda, who calculated over 6.4 billion pounds of contained copper potential on Anaconda lands alone (not NI 43-101 compliant), and the private land consolidation completed by the Company, the deposit remains woefully underexplored for such a legacy asset. These exceptional results validate our belief that systematic exploration can unlock substantial new zones of high-grade copper mineralization and significantly expand the known footprint of the deposit."*

Background of the Bear Deposit:
The Bear deposit is a large porphyry copper exploration target situated on private lands and located approximately three miles north of Anaconda's former Yerington open pit mine, in Lyon County, Nevada. The deposit was first identified by Anaconda in 1961. From 1961 to 1967, Anaconda drilled 38 drill holes totaling 101,827 ft in order to better define the deposit. From 1969 to 1973 Phelps Dodge acquired the eastern part of the property and drilled an additional 12 holes, totaling 34,008 ft, which further expanded the deposit to the east. In 1980, Anaconda developed a non-compliant NI 43-101 resource estimate* of 735 Mt of 0.44% TCu that only covered a small portion of the footprint of the deposit (Figure 2).

The footprint of the deposit covers more than three-square miles and 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. Lion CG, through its wholly owned subsidiary Singatse Peak Services, LLC (SPS), has consolidated the property through private land lease/purchase option agreements and controls a land position of approximately 2,330 acres.

In a program funded by Freeport Nevada LLC ("Freeport") in 2015 and 2016, the Company drilled six deep holes totaling 20,275 ft, which demonstrated an extension of the deposit to the north-northeast. Drilling by Anaconda, Phelps Dodge and Lion CG all intersected thick zones of copper mineralization ranging from 490 ft to 2,843 ft thick (Figure 3, Table 2). No oxide mineralization or supergene enrichment has thus far been identified at the Bear deposit. The zones of primary sulfide mineralization remain open in several directions where the limits of mineralization are not closed off by drilling.

Given the very large footprint of the known mineralization, the deposit remains highly attractive for further exploration with core holes currently spaced at 500-to-1,000-foot intervals.

*Historical estimates of grade and tonnage or of contained metal were obtained from available historical records produced by Anaconda and Phelps Dodge and do not use current mineral resource categories under NI43-101. The Company believes historic information is relevant for planning purposes but should otherwise not be relied upon. Additional drilling and analysis would be required to verify such historical estimates. A qualified person has not completed sufficient work to classify the historical estimates as a current mineral resource. The Company is not treating the historical estimates as current mineral resources.

Bear Deposit 2023 Drilling Results:
Two angled diamond core drill holes, B-053A and B-054 were collared and drilled to depths of 3,503 ft and 3,458 ft, respectively, northwest along the mineralization trend previously identified by Anaconda legacy drill holes B-013 and B-014. Legacy drill holes B-013 and B-014 intersected large zones of sulfide mineralization, including intervals with grades greater than 1.0% TCu. Higher copper grades intersected in legacy drill holes occur within a felsic endoskarn host rock, a magnetite-chalcopyrite rich rock associated with occurrences of massive chlorite and actinolite which are related to the contact of the older host rocks of granodiorite and younger quartz monzonite. The extension of the endoskarn zone and mineral assemblage was intercepted in B-053A and B-054 along a northwesterly projection. Though the total copper grades are less than those reported in legacy holes, it is not unexpected to have strongly variable copper grades within the endoskarn zones due to the irregular distribution of copper typically found in this type of geologic environment.

The intercepts in B-053A and B-054 have expanded the Bear deposit 1,850 ft in the northwesterly direction as represented by a +200 ft grade times thickness zone (Figure 4). This same zone is seen in drill hole B-015, located 1,900 ft west-northwest, containing 125 ft of 0.44% TCu, including 44 ft of 0.76% TCu. Legacy drill holes B-007, B-009A, B-011, and B-012, on a north-south drill line at the western edge of the known deposit, were too shallow to test for the western extent of the Bear deposit as shown in Figure 4. Deeper step-out drilling west-northwest of these legacy drill holes are expected to further expand the deposit footprint.

B-053A and B-054 are the only angled drill holes ever drilled in the deposit and have therefore now better defined the structural orientation of the mineralized zones. The quartz monzonite porphyry dikes and associated mineralization strike roughly east-west to northwest-southeast with a 45° northerly dip as shown in the cross-section (Figure 5). Mineralization at the Bear deposit appears to include a first pulse that occurred with the intrusion of quartz monzonite into the granodiorite and is characterized as a skarn along the contact. A second pulse of mineralization appears to have occurred, where quartz monzonite porphyry dikes intrude into the quartz monzonite and mineralized veinlets are strongly seen in and along the margins of the porphyry dikes.

In general, porphyry copper deposits have a high pyrite shell, with lesser chalcopyrite mineralization surrounding a zone with higher copper grades. Drill holes B-053A and B-054 contain sulphide mineralization percentages consistently average greater than 3%, and in some cases up to 35%. These are some of the highest percentages of sulphide mineralization ever observed in any of the drilling completed at Bear. The high sulphide mineralization percentages in B-053A and B-054 may be indicative of a high pyrite shell and proximity of a higher-grade copper mineralized zone.

Future exploration work is recommended to focus on the mineralized quartz porphyry dikes which remain open down-dip to the north and up-dip to the south, as well as along strike to the east and west. Higher grade zones might be found to occur in well-developed felsic skarns or within closely spaced quartz porphyry dikes with overlapping zones of altered mineralization. The source of the mineralized quartz porphyry dikes remains an untested target below the current depth of exploration.

Additional 2023 Exploration Results:
Exploration objectives outside the Bear deposit included evaluation of the following drill targets (Figure 1):

  • MacArthur expansion to the northeast and southeast (MacArthur East and MacArthur Wedge targets)
  • Mason Pass Prospect
  • Reno Prospect
  • Singatse Target

A total of 9,945 feet of reverse circulation drilling were completed to evaluate these four targets. Additionally, a surface geochemical sampling and testing grid across the MacArthur-Mason Pass area is currently in progress and scheduled to be completed in late 2023.

Results Include the Following Highlights:

  • The one reverse circulation drill hole at MacArthur Wedge identified 5 to 10 ft zones of oxide and sulphide mineralization with grades up to 0.25% TCu
  • Reverse circulation drill holes at MacArthur East identified 10 to 20 ft zones of chalcocite enrichment with grades up to 0.25% TCu (5 ft intervals up to 0.38% TCu)

Please see Table 3 for a list of significant intercepts from the 2023 exploration program.

MacArthur Expansion:
Three reverse circulation drill holes were drilled on the northeastern edge of the current resource pit shell to test IP geophysical anomalies (MacArthur East) and one additional drill hole 1,800 ft southeast of the current pit shell (MacArthur Wedge). Two drill holes (QM-333 and QM-334) at MacArthur East intercepted 10-20 ft intervals of oxide or chalcocite mineralization above the IP anomalies. Below the enrichment zone, the IP anomalies were characterized by 2-3% (locally higher) pyrite. QM-332, southeast of resource shell also intercepted 5-10 ft zones of low-grade oxide mineralization.

Mason Pass Prospect, Reno Prospect, and Singatse Target Exploration:
Additional drilling took place at the Mason Pass Prospect, Reno Prospect, and Singatse Target locations. Four reverse circulation drill holes were completed at the Mason Pass Prospect with depths ranging from 500 to 600 ft. These drill holes tested for mineralization below and adjacent to trenches excavated in 2022 that discovered oxide copper grades up to 0.70% over 20 ft (see December 13, 2022 news release).

Four reverse circulation drill holes were completed at the Reno Prospect with depths ranging from 500 to 1,300 ft. These drill holes tested for a potential eastward extension of plus 0.2% TCu oxide and sulphide intercepts seen in 1960's and 1970's legacy Anaconda drilling and to test for expansion of mineralization intersected in the 2022 drilling program (see November 10, 2022 news release). Two of the drill holes were cased for future core drilling to test at-depth IP geophysical anomalies. One of these cased drill holes intersected an interval of 5 ft of 1.01% TCu.

A single drill hole at the Singatse Target was intended to test for a faulted northwest extension of the mineralization from the Yerington pit.

Quality Assurance & Control:
All samples were collected via reverse circulation or 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 delivered to ALS Geochemistry in Reno or, alternatively, were picked up by ALS Geochemistry, NV for sample preparation. Multi-element analyses were completed using an aqua regia digestion and ICP-MS finish in North Vancouver, BC. Thirty-six samples from one drill hole were analyzed by Paragon Geochemical using a multi-element analysis with an ICP-MS finish in Reno, NV. 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.
