Yesterday after market close, Core Assets Corp. (CSE: CC; market capitalization: $2.6 million) made the landmark announcement of expanding its property by the factor of 9, now controlling 148 km² of prospective ground at the northern extent of British Columbia‘s world-famous Golden Triangle. When looking to discover a large and well-mineralized copper-gold porphyry deposit, you better have a large property located at the right place. 

With this major move of consolidating the entire area around its Blue and Silver Lime properties, Core Assets makes the impression of intimately knowing that they can make a lasting impression to its shareholders by securing an extensive land package ahead of a major discovery it believes it can make, and before a rush into this vastly neglected district may start.

Most importantly, Core Assets has some impressive facts and figures to back up its strategy of becoming the premier player in the Atlin Mining District:

1) Big Potential: The historical drill and sampling results recorded on the property are an indication that a great opportunity might await to be unlocked.

2) Structure is Key: “Core Assets now holds 100% (15 km) of the glacially retreated portion of the Llewelyn Fault Zone, (...) a regional thrust fault that runs directly through the property and thought to be the main transport corridor for the mobilization and concentration of high-grade metals seen at surface on the property.“

Map of the Land Acquisition: Core Asset’s property holdings known as the “Blue” and “Silver Lime” properties have now been amalgamated and increased from a land area of 1,657.66 hectares (16.58 Km²) to 14,814.86 hectares (148.15 km²). (Source: Core Assets’ news-release of September 2, 2020)

According to Core Asset´s news-release (September 2, 2020) with pictures added by Rockstone:

Acquisition Highlights

• Land position increased substantially by nine times the original size to 148.14 Km²

Core Assets now holds 100% (15 km) of the glacially retreated portion of the Llewelyn Fault Zone, running from the northernmost extent of the existing Llewelyn Glacier, north to Atlin Lake. The Llewelyn Fault is a regional thrust fault that runs directly through the property and thought to be the main transport corridor for the mobilization and concentration of high-grade metals seen at surface on the property.

• The Blue property hosts a historical diamond drill hole that assayed 173.2 meters of 0.27% Cu from surface, 1.60% Cu from 173.2-179.2 meters,1.40% Cu from 186.2–194.0 meters and is open in all directions.

• The Silver Lime property hosts massive sulfide at surface with historical channel samples of 3.3 g/t Au, 2,641 g/t Ag, 0.15% Cu, 2.5% Pb and 3.32% Zn, 2.56% Sb over 2.2 meters and has never been drilled to date.

• Core Assets hopes to formulate and execute a regional magnetic geophysical survey to better delineate secondary and tertiary structures associated with mineralization on the property and better define drilling targets.

CEO David Hodge comments, “Core Assets continues to build its land position within the Atlin Mining Camp, and hopes to become the premier explorer of the northernmost extent of the Golden Triangle saga. In addition to this, these newly acquired claims will help solidify potential deep seated secondary and tertiary structures that are fed by the Llewelyn Fault Zone. This will allow for a more effective exploration program as we move to active exploration at the Blue and Silver Lime projects.“

Core Assets believes that the south Atlin Lake area and the Llewelyn Fault Zone, which runs approximately 140 km from the Yukon border to the Juneau Ice Sheet in the United States, has been neglected since the last major exploration campaigns in the 1970‘s. The last 50 years have seen incremental advancements in the understanding of porphyry, skarn and carbonate replacement type deposits both globally and in the Golden Triangle area, with new discoveries being made annually. The sum of this knowledge is now coming together in discrete and effective exploration models that the Company believes could drive a major discovery. Core Assets intends to leverage this shift in understanding and become one of the most extensive explorers in the northernmost extent of the Golden Triangle saga.

The Core Assets team has significant experience and knowledge in the Atlin Mining District. They have studied the entirety of the south Atlin Lake, where there is an opportunity for world class discoveries and mine development. The acquisition of these additional claims is yet another demonstration of this strategy as we continue to define high priority targets.

About the Blue and Silver Lime projects

Blue Property

In 2018, the Company sent a geological team to the Blue property for preliminary surface sampling. The field crew observed three areas of skarn exposure with massive and disseminated visible sulfide along the western side of the Llewellyn Regional Fault Zone. 28 grab samples were taken and sent to the laboratory for geochemical analysis and returned values of up to 1.57 g/t gold, 46.5 g/t silver and 8.46% copper.

In 2019, Core Assets contracted Aurora Geosciences Ltd. for the execution of an induced polarization geophysical survey over the areas of high priority mineralization which confirmed and highlighted areas of elevated chargeability response over visible skarns and identified multiple chargeable porphyry style targets.

Later in 2019, Nick Rodway, P. Geo. (Director of Core Assets Corp) and Matthew Carter (Qualified Person of Dahrouge Geological Consulting Ltd.) visited the property to reanalyze some of the high priority areas identified by the 2018 and 2019 programs. The program successfully confirmed elevated gold, silver and copper values.

The amalgamation of Core Asset’s newly obtained geological information, and the historical exploration data, including the 1973 exploration program undertaken by Rio Plata Silver Mines Ltd., where a single diamond drill hole assayed 173.2 meters of 0.27% Cu from surface, 1.60% Cu from 173.2-179.2 meters and 1.40% Cu from 186.2–194.0 meters will serve as a bases to complete further structural analysis for placement of drill holes. This could potentially lead to a new porphyry style discovery in British Columbia.

Silver Lime Property

The Silver Lime Property is located just 10 km west of the Blue Property (now contiguous) and was originally acquired by Core Assets as a secondary project. Through rigorous desktop geological study by Core Assets’ technical team, it has been deemed that the same exploration model revolving around fluid mobilization of the Llewellyn Fault Zone also applies to the west.

Historically, the Silver Lime Property consisted of two significant mineral occurrences known as the Falcon and Jackie showings. The Falcon showing was discovered by Carmac Resources in 1990 and consists of two northwest trending quartz veins. Mineralization comprises galena, sphalerite, pyrite, chalcopyrite, arsenopyrite and stibnite. The vein system is exposed for 25 meters and the strike extensions are covered by talus. Individual veins are up to 1.2 meters wide.

To the northwest, a quartz-feldspar porphyry breccia contains smaller quartz veins with semi-massive arsenopyrite and stibnite. A 2.20 meter wide sample of the vein system assayed 3.3 g/t gold, 2,641 g/t silver, 0.15% copper, 2.5% lead and 3.32% zinc, 5.0% arsenic and 2.56% antimony (Assessment Report 21162).

In 2018, Zimtu Capital Corp., as part of a helicopter reconnaissance program, prospected the property taking 8 samples. The results confirmed the program that Carmac did in 1990, returning values reaching 1.16 g/t gold, 913 g/t silver, 12.45% zinc and >20.0% lead.

The Silver Lime Property potentially fits a carbonate replacement deposit model (CRD). Massive sulphide pods occur in limestone and biotite-muscovite-sericite schists generally near the contacts between the units. Large zones of limonite alteration, cut by alaskite and hornblende porphyry dikes, usually surround the pods. The lenses appear to be widest near the dikes. Several faults follow the general direction of the dikes, suggesting structural control on the mineralization. Sulphides comprise galena, sphalerite chalcopyrite, pyrrhotite and pyrite. The pods are up to 30 meters long and 6 meters wide. The smaller pods host sphalerite and galena mineralization and the larger pods vary mineralogically along length. Galena, quartz and calcite dominate the northwest changing to pyrrhotite, chalcopyrite and pyrite in the centre and border areas (Minfile 104M 031).

Transaction Outlined

Under the terms of the agreement, the company acquired a 100-per-cent interest in the claims by paying $23,025.11 upon signing of the purchase agreement. The vendor shall retain a 2.0-per-cent net smelter return royalty (NSR) on the property, of which the company shall have the right to purchase half (1.0 per cent) for $1 million.

Regional & Property Geology

“A major regional structure, the Llewellyn fault, juxtaposes the Nisling terrane, a Proterozoic to lower Paleozoic aged continental margin assemblage (west), against the Upper Triassic to Middle Jurassic northern Stikine terrane (east)... The Llwellyn fault exceeds 100 km in length, striking northwest from the Tulsequah area to the British Columbia-Yukon border. It is characterized as a steeply dipping, brittle dextral strike-slip structure (Mihalynuk et al., 1994, 1999)... In this area, the Stikine terrane is comprised of Upper Triassic strata belonging to the Stuhini Group; this group consists of limestones, arkosic sandstone, basaltic flows and breccia, debris-flow conglomerate, turbiditic volcanic sandstone, and argillite (Bultman, 1979; Milhalynuk and Mountjoy, 1990). The northwestern part of the Stikine terrane is an exceptionally prolific area for economic ore deposits and has been dubbed “The Golden Triangle”. The rocks of this area are known to host volcanogenic massive sulphide, alkaline porphyry Cu-Au, and epithermal precious metal deposits.

”Exposures of lithologies belonging to the Stuhini Group are poorly represented on the Property, dominantly occurring along its eastern or northern borders. The lowermost unit of the Stuhini Groupeast of the Llwellyn fault zone, is a sheared, brecciated, and locally calcite veined basalt. Intrusive granitic units on the Blue Property are comprised of biotite granite to granodiorite and biotite-hornblende granite to alaskite. These granitic intrusions dominantly span a temporal range from the Late Triassic to the Mid-Cretaceous, though younger intrusives of smaller relative volumes occur throughout the area (Jackson et al., 1990).

”The Blue Property straddles the eastern boundary of the Coast Belt and the western boundary of the Intermontane Belt ... along the Hoboe Creek Valley in the Canadian Cordillera... The Coast Belt is comprised of mainly granitic rock spanning a Jurassic through Cenozoic temporal range. The remainder of the Coast Belt are Proterozoic, at the latest, to Holocene complexly deformed, high grade metamorphic sedimentary and volcanic rocks formed in magmatic arcs or accretionary complexes (Monger and Price, 2002). The Intermontane Belt in northwestern British Columbia is represented by the Stikine physiographic unit. Sedimentary, granitic, and volcanic rocks geologically define the Intermontane Belt spanning the following facies and temporal ranges: Devonian to Early Jurassic island arcs and accretionary complexes; Middle Jurassic to Cenozoic continental arc, marine, and terrestrial clastics; Devonian to Cenozoic granitic rocks (Monger and Price, 2002).” (Source: Technical Report on the Blue Property, 09/2019)
