Terrane: Wawa-Abitibi
Belt: Abitibi
Geological Age: Archean
Metamorphism Grade: Greenschist
Dec 07, 2005 (C Salo) - Most of the bedrock underling the Buffonta and adjacent claims is indicated to consist of weakly metamorphoposed greenschist or lower facies subaqueously deposited tholeiitic basalt and volumetrically minor intercalated interflow sediment of the Kinojevis Group. Intrusive rocks include what is locally termed the Garrison Stock, a 4 km wide triangular monzonitic body which occupies an area of about 20 square kilometers. The southwest Garrison Stock contact is about 1 km northeast of the open pit. Felsic dikes intrude the supracrustal rocks in the open pit area and in the footwall of nos. 5 and 6 zones. Some of these dikes are believed to represent apophyses of the Garrison Stock. Mafic dykes variously reported to be or lamprophyric and kimberlitic composition area also present. The Archean supracrustal rocks underlying most of the claim group are about 3.3 km south of the locally east striking structurally complex Porcupine-Destor Fault Zone. The for a northeast striking, steeply south dipping, and south facing monocline which occupies part of the north limb of the east striking and east plunging Blake River Synclinorium.

Dec 07, 2005 (C Salo) - Gold mineralization is hosted by variably foliated volcanic rocks within a contact metamorphic aureole of amphibiotic grade. Anomalous gold tenors are know to occur in at least 3 distinct areas, termed here the open pit zone, NO. 5 Zone and NO. 6 Zone. In the open pit zone gold mineralization is hosted by variably foliated amphibolite grade massive, pillowed, variolitic and felspar phyric basalt and minor intercalated interflow sediments. The despot is with an amphibolite grade contact metamorphic aureole. On the walls of the pit, volumetrically minor pink fine to medium grained undeformed felsic dikes composed of subequal amounts of potassium felspar, and plagioclase and 10-15% of quartz, less than 5% biotite, and accessory amounts of chlorite, carbonate, apatite, pyrite, amphibole and sericite intrude the host metavolcanic rocks. Both the metamorphosed supracrustal rocks and the felsic dikes have been intruded by a least three types of veins, including: nonauriferous folded and or boudinaged garnet-epidote veins, nonauriferous folded epidote-actinolite-sphene carbonate - garnet veinlets and auriferous planar deformed quartz veins and vein braccia around which are developed prominent grey to brown colored pyritic alteration halos. The NO. 5 Zone consist of auriferous steeply south-west dipping shear which strikes 142. The shear maybe up to 12 m wide locally. The zone is reported to consist of shear controlled quartz-carbonate vein breccia containing coarse grained pyrite which occurs on either side of the 5.5 m wide altered lamprophyre or kimberlite. Description of gold mineralization is similar to descriptions of the present at the open pit zone. The NO. 6 Zone consist of steeply dipping 112 striking shear which has been traced at least 335 m along strike. It is similar to the NO. 5 Zone which truncates/joins at its southeast end. Gold mineralization is reported to be similar to No. 5 Zone and the open pit zone.
Dec 07, 2005 (C Salo) - The visible alteration halos have sharp and well defined outer margins which are oriented parallel to the veins which they surround. Thin section petrography indicates that vein marginal alteration consist of cryptic alteration: progressive replacement of amphibole by chlorite and ankerite and progressive replacement of plagioclase by carbonate; outer visible alteration zone: complete replacement of amphibole by chlorite and ankerite, the complete sericitization and magnetite; and inner visible alteration zone: development of potassium feldspar at the expense of chlorite, sericite, and ankerite. Pyrite occurs as idioblastic cubes within the zones of visible alteration.C
