Overview
The Peacock property is located in the western portion of the province of Quebec, Canada, about 70 km north of the town of Amos and 40 km west of the Sleeping Giant Gold project from Mines Abcourt. It consists of 456 claims covering an area of 22,567.89 hectares distributed in two separate blocks. The property is easily accessible by a network of logging roads.
A wide variety of exploration work has been conducted on the Peacock property and its immediate surroundings since 1948. Much of this work consisted of compilation studies, trenching, stripping, sampling, geophysical surveys and drilling.
The areas host many projects that have reached an advanced exploration stage or even production. The gold potential of the region is notably illustrated by the Sleeping Giant gold mine (3,158,698 tons at 10.48 g/t Au) located 40 km east of the Peacock property. Between 2009 and 2012 Maudore Minerals Ltd. performed prospecting work on the Peacock property area. It consisted of prospecting, stripping, mapping and sampling. A total of 1,270 samples (including 179 economical samples and 1,091 lithological samples) were collected.
Geology and Mineralization
The Peacock property area lies within the east-central portion of the Abitibi Subprovince in the Superior Province of the Canadian Shield. This subprovince consists of a large Archean belt of volcano-plutonic rocks that extends more than 600 kilometres from Timmins in Ontario to Chibougamau in Québec. The belt is bordered to the north by granitic rocks of the Opatica Subprovince and to the south by sedimentary rocks of the Pontiac Subprovince. The southern limit of the Abitibi Subprovince is roughly marked by the Larder Lake—Cadillac Fault. It also happens to be one of the richest mining regions in the world and has produced large amounts of gold, copper, zinc, silver from Timmins, Kirkland Lake, Rouyn- Noranda, Val-d’Or, Matagami and Chibougamau mining districts.
The Peacock property area is mostly underlain by volcanic rocks. This sequence is characterized by mafic volcanism with superimposed felsic volcanics. The volcanic sequence is dominated by massive, pillowed and brecciated basalt of tholeiitic composition. Mafic volcanic rocks are intercalated with sedimentary and felsic volcanic rocks. Most of the volcanic episodes took place from 2.75 to 2.70 Ga and was closely followed by deformation, regional metamorphism and an episode of plutonism. Sedimentary assemblages occur as thin, discontinuous, east-trending belts more than 100 km in length. They are intercalated with volcanogenic conglomerates, banded iron formations, shales and cherts. The volcanic rocks were affected by the Kenorean north-south regional compression. This compression resulted in a well-developed E-W schistosity flowing around regional plutons.
A lithogeochemistry study of the areas reveals many felsic rocks on both blocks of the property. On the western block, field observations on historical stripping revealed a NW-SE orientation in the volcanic rocks near the contact with the Mistaouac Pluton. The first derivative component of the magnetic survey indicates that the overall orientation of the band of felsic rocks becomes more N-S moving southward. These felsic rocks extend to the north and could possibly be the stratigraphic equivalent of the felsic volcanic sequences hosting the Joutel base metal deposits some 30 km north of the Peacock west block. The Joutel district produced a total of 11.1 Mt of 2.0% Cu, 0.7% Zn and 6.2 g/t Ag out of two mines between 1966 and 1975.
The Peacock property shows potential for three (3) deposit types: volcanogenic massive sulphide, greenstone-hosted quartz-carbonate veins, and nickel-copper sulphide. On the Bieber showing grab samples returned up to 0.97% Cu. Prospecting also led to the discovery of significant Au, Ag, Cu and Mo values in a quartz veins (sample L230796: 1.3 g/t Au, 38.8 g/t Ag, 2130 ppm Cu and 2890 ppm Mo). Also, many other quartz veins were found on the Gaby stripping. The best results are in the following table:
