Disraeli Project: PGE-Nickel-Copper

Status

  • 100% owned, Non-core project.
  • Available for joint venture.

Target

  • Chonolith hosted massive and disseminated sulphide.

Location and Setting

Disraeli is located 40 kilometers north of Clean Air Metals Inc’s TBN project and only 50 kilometers east from Impala Platinum Holdings Ltd’s (“Implats”) Lac Des Iles palladium mine (Figure 1 and 2).

Land Status

The Disraeli Property consist of 85 mining claims that are 100% owned, covering approximately 4,200 hectares.

Geology and Mineralization

The West Nipigon Lineament (Figure 2), is believed to be a control structure for the emplacement of the TBN (Clean Air Metals Inc.), Seagull (Quadro Resources Ltd.), and Disraeli intrusions and is prospective for additional magma conduits such as those found at TBN and Escape Lake.

A high-resolution drone magnetic survey identified a very strong, reversely polarized magnetic body beneath the southeast bay (Hook Bay) of Disraeli Lake (Figure 3 and 4). Reversely Polarized rocks are a key indicator for early mafic-ultramafic intrusives associated with PGE-Ni-Cu mineralization in the Mid-Continent Rift. Portions of the nearby TBN, Escape Lake, Sunday Lake (Implats), and Marathon (Generation Mining) deposits are also reversely polarized.

The presence of airborne AeroTEM EM anomalies suggest the possibility of not only disseminated mineralization but also semi massive or even massive sulphides. A lake sediment survey conducted in 2020 has shown a consistently greater ultramafic signature beneath Hook Bay compared to the rest of the Disraeli Lake. Ultramafic rocks were also observed along the western shore of Hook Bay. All of which point to this area being a much more primitive part of the Disraeli intrusion, and hence potentially close to the magma conduit which fed the intrusion.

The Disraeli intrusion has seen much less exploration than adjacent intrusions in the Nipigon Plate There is a precedent for magma conduits being located beneath lakes. Both TBN and Escape Lake magma conduits occur beneath the Current and Steepledge lakes, respectively.

In January 2021, the Company drilled 5 ice-based holes totalling 1,233 meters to test several airborne EM conductors and a reversely polarized magnetic body under Hook Bay of Disraeli Lake. One conductor was found to be caused by massive magnetite copper-cobalt-nickel Skarn, while several of the airborne EM conductors proved to be the result of lake sediments, (Table 1). The reversely polarized magnetic body requires additional follow up as it was not adequately explained, it may be the result of a reversely polarized granophyric sill located below the Disraeli Intrusion and/or a magnetite skarn.

The copper-cobalt-nickel magnetite skarn is of particular interest as it is enriched in cobalt (Table 1). The mineralization intersected in the recent program is very similar to skarn mineralization intersected 1.5 kilometers to the south in holes U17-01 and U17-02 by a previous operator. These holes intersected up to 0.13 % cobalt over 2.0 meters and 0.16 % cobalt over 0.45 meters respectively.

This cobalt bearing skarn-style mineralization has now been intersected by 4 holes on the Disraeli project indicating it is much more widespread than previously thought. The mineralization is hosted in the carbonate-rich (dolomite) Rossport unit of the Sibley Formation, mostly likely representing replacement of stromatolitic beds within the sediments. It consists of massive to stringer magnetite with 10-20% sulphides consisting of pyrite, pyrrhotite, and chalcopyrite (Figure 6). This skarn mineralization is indicative of widespread hydrothermal alteration associated with either the Disraeli intrusion or another unknown mafic-ultramafic intrusion at depth. Additionally, copper mineralization is known to occur in the greater Disraeli Lake area as chalcocite and malachite hosted in stromatolites with the Sibley sediments; grab samples collected by the Ministry of Northern development in 2011 returned up to 1.57% Cu (Mineral Deposit Index MDI52H02NW00002) from this style of mineralization. All of this indicates a significant magmatic hydrothermal system was present in the Disraeli Lake area and suggests thicker and higher-grade areas of cobalt skarn mineralization are yet to be discovered.

Proposed Exploration Program

Further prospecting and drilling is proposed to investigate the cobalt-rich magnetite skarn-type mineralization. Additionally, drilling is also proposed to test the down hole EM conductor identified during the program, that could not be tested before the ice road melted due to the Spring thaw.
