Lac Guéret East Graphite Property
The Lac Guéret East Graphite Property and Lac Guéret South Graphite Property are both located within the exploration friendly jurisdiction of Quebec, in the Manicouagan Regional County Municipality, three hours driving time from the city of Baie-Comeau. Easy access is provided via a major secondary road and numerous tertiary and forest roads that traverse the property.
The properties are situated in the geological Grenville Province and part of the Plan Nord region, Quebec’s highly regarded sustainable development initiative.
The Lac Guéret East Graphite Property consists of 42 claims covering 2,269 Ha and is prospective for Graphite. Berkwood holds a 100% interest in the property. Berkwood also has an option to earn a 100%-interest in the Lac Guéret South Graphite Property which consists of 107 claims totalling 5788 Ha.
The Lac Guéret East Graphite Property is adjacent to the eastern edge of Mason Graphite’s significant Lac Guéret Project. Mason Graphite’s advanced Lac Guéret Project has an NI 43-101 compliant mineral resource estimate with measured & indicated mineral resources of 67.5 million tonnes grading 17.2% Cgr (Carbon as Graphite), inlcuding 9.7 million tonnes grading 31.2% Cgr.
The Lac Guéret South Graphite Property borders the southern boundary of Mason Graphite’s advanced Lac Guéret Project and is adjacent to, on all sides, a separate Mason Graphite property in the Lac Guéret region, the Capitaine Cosmos Graphite Prospect, which lies 12 km to the southwest of Mason Graphite’s Lac Guéret Project.
The Lac Guéret East and South Graphite Properties shares a similar prospective geological environment as Mason Graphite’s Lac Guéret Property (located adjacent and to both properties), including along strike stratigraphic units and structures. Graphite in the vicinity ranges from 3% to 40% Cg (averaging 20.4% at Mason Graphite’s Lac Guéret Deposit) and exhibits flakes of up to 5 mm in diameter. Large flake graphite is 0.2 mm and above.
The Properties are part of the Archean Ulamen Complex (2780 to 2680 Ma) mainly composed of (i) gneissic tonalite and granulitic tonalite gneisses interlayered with (ii) minor mafic metavolcanics and metagabbros. The Archean Ulamen Complex contains units of Paleoproterozoic units reported to be metasedimentary in origin and stratigraphically correlated with the Gagnon Group. Units of the Gagnon Group present on or adjacent to the Properties include: biotite, garnet, sillimanite paragneisses and graphitic schists of the Nault Formation; iron formations with ferruginous quartzites and cherts of the Wabush Formation; quartzites of the Wapussakatoo Formation (1868 Ma); and dolomitic and calcitic marbles of the Duley Formation (Source: Quebec government public file Sigeom MERQ RG2013-01).The overall structural pattern is an arc with gneissic fabrics striking NNE-SSW in the Lac Guéret East Property passing through E-W to WNW-ESE in the Lac Guéret South Property.
In the proximal area of the Properties, seventeen (17) Graphite prospects are reported, including the Mason Graphite Lac Guéret deposit and Mason Graphite Capitaine Cosmos Graphite Prospect which returned up to 34.1% Cgr and 0.8 g/t Au over one meter (Source: Quebec government public file Sigeom MERQ GM60839). Berkwood’s Lac Guéret South Graphite Property surrounds the Capitaine Cosmos Property where Graphite mineralization is reported to occur as semi-massive to massive (up to 90% Cgr) interfolded lenses and veins intimately associated with silicate and sulfide iron formations, sulfide schists, dolomites and calcites, quartzites, amphibolites, calc-silicates and metamorphosed, aluminous and ferrous alteration.
Geologist, Alain Berclaz, P. Geo and CEO of Abgéoconseil Inc. consultants, made a recent site visit to the the Properties. From his historical work compilation and field observations, Mr. Berclaz notes that a fieldwork program with the objective to delineate high-quality conductors associated with new prospective Graphite targets or with extensions on strike with known massive Graphite mineralization is of particular interest within Berkwood’s Lac Guéret South Property and should be of the highest priority. His recommendation for initial fieldwork in order to rapidly advance the project to a drilling stage, is to immediately commence with a detailed magnetic-electromagnetic (MAG-EM) helicopter-borne geophysical survey.
