Geological Belt Overview
Champagne Resource's claims in Kirkland Lake are centrally located in the Abitibi Greenstone Belt ("Abitibi Belt"), in the Superior Province of the Canadian Shield. The Abitibi Belt is the largest Archean (i.e. greater than 2.5 billion years old) belt of its kind in the world and is also one of the most prolific in terms of mining production. It is a 750 kilometre long by 250 kilometre wide belt of deformed and metamorphosed volcanic and sedimentary rocks.
The Goodfish Kirana property occurs within the Western Abitibi subprovince. The structural complexity and poor exposure of the subprovince have made comprehensive stratigraphic syntheses difficult. Instead, the district has been divided into a number of "tectonic assemblages", on the basis of similarities in stratigraphy, lithochemistry, age dates and aeromagnetic and airborne EM signatures. Since the initial division of the Abitibi greenstone belt into tectonic assemblages, more accurate and more abundant age dates have enabled a simplified and improved delineation of the assemblages to be made. The Property is underlain by the lower unit of the Blake River Assemblage. This unit is 2704 to 2701 Ma in age, and is dominated by tholeiitic mafic volcanic rocks, with lesser felsic volcanic rocks. Minor amounts of Timiskaming assemblage sediments occur in the northern and southeastern tips of the Property.
Major gold deposits in the Western Abitibi Subprovince are typically proximal to either the Destor Porcupine Break or the Larder Lake Cadillac Break, or to associate faults. In Kirkland Lake, most deposits are spatially associated with the Kirkland Lake Main Break. The Property is north of both the Cadillac-Larder Lake Break and the Kirkland Lake Main Break. The extension of the latter passes just south of the Property. The Property is also north of the package of rocks that is most prospective for gold deposits (Timiskaming sediments + alkalic intrusions).
The Property is underlain mostly by Archean mafic volcanic rocks, but is locally intruded by quartz-feldspar porphyry intrusions, particularly in the Goodfish Block. Mafic intrusions occur in the southern part of the Eastern Block, and in the eastern part of the Southeastern Block. Minor amounts of intermediate volcanics occur in the western portion of the Northern Block. Timiskaming sediments occur in the southern half of the Southeastern Block, and underlie Nettie Lake in the northern part of the Airport Block. An alkalic volcanic or intrusive unit is interlayered with these sediments in the Southeastern Block and ice flow indicators on the Property vary from southeast to immediately west of south.
