Geology Comments

Feb 11, 2016 (R Degagne) - The shaft is about 1,500 m southwest of the west northwest striking Contact Fault, which separates steeply dipping, north facing tholeiitic basalts of the (Archean) Stoughton-Roquemaure Group to the north from Porcupine Group sedimentary rocks to the south. Several north northeast striking cross faults with apparent associated horizontal displacements of no more than about 100 m have been identified southeast of the outcrop area where sediments are well exposed. Detailed mapping has also identified two stages of deformation in the area, both of which postdate the intrusion of the felsic intrusive bodies.

Lithology

Lithology Comments

Feb 11, 2016 (A Wilson) - The Beatty Syndicate is assumed to have deepened the inclined shaft. The shaft which dips 70º N25W, has been sunk on a fractured zone in the sediments. This zone, or parallel zones has been explored on surface by a number of pits and trenches over a length of 700 ft

Feb 11, 2016 (R Degagne) - The shaft area is underlain mainly by sparsely exposed weakly metamorphosed (greenschist or lower metamorphic facies) north facing and overturned, south dipping medial to distal turbiditic wackes and siltstones of the (Archean) Porcupine Group which are mantled by variable thickness of glacial deposits. Wackes are characteristically grey colored, occur in beds which are several centimetres to several metres in the thickness, and contain distinctive pinhead size rounded to subangular quartz grains. Siltstones are usually grey colored, occur as finely laminated to massive beds up to several decimetres in thickness, and are intercalated with the wackes in variable proportions. Laminated chert and horizons of intraformational conglomerate also to occur in the area. Intrusive rocks near the occurrence include: a) felsic bodies intruding sediments (the closest such body is about 1,600 m east of the shaft area); b) a northeast striking olivine diabase dike of the (Proterozoic) Abitibi Swarm which is exposed about 600 m northeast of the shaft area; c) a narrow (approximately 60 m wide) west northwest striking dioritic sill-like body which intrudes sediments about 170 m southwest of the shaft; d) generally north striking diabase dikes of the (Proterozoic ) Matachewan swarm, several of which are exposed immediately west of the shaft; and e) narrow (generally metre scale) lamprophyre dikes. Sediments marginal to the shear on which the trench and shaft are developed consist dominantly of grey, fine grained wackes with abundant pinhead size rounded quartz grains. Interbedded with the wacke horizons are narrow (generally < 10 cm) grey siltstone and cherty siltstone beds.

Mineralization

Mineralization Comments

Feb 11, 2016 (A Wilson) - A grab sample collected by J. Satterly from a quartz vein in argillite assayed 0.09 oz./t Au. There is very little mineralization in the wallrock. A grab sample collected by Maude Lake Gold Mines Ltd. from a quartz vein in the shaft area reportedly assayed 0.018 oz../t Au. Grab samples in the vicinity of the shaft have returned gold values ranging from 1.47 g/t Au to more than 12.45 g/t Au. The best assay from the Maude Lake Gold Mines drill hole M-97-04, drilled northeast of the shaft, in claim 700895 intersected 0.85 m assaying 1146 ppb Au.

Feb 11, 2016 (R Degagne) - Muck samples obtained by the present writer from the waste pile on the shaft outcrop indicate that the quartz vein material is hosted by sheared, and pervasively carbonatized (Fe-dolomite), sericitized, and silicified sediments which have been subsequently fractured and non pervasively carbonatized (calcite). Sulphide minerals observed in dump grab samples consist of very fine to fine grained disseminated pyrite, pyrrhotite and, very rarely, chalcopyrite. Aggregate sulphide content of dump samples, rarely exceeds 4%. Sulphide minerals occur both within and marginal to quartz-actinolite vein material, in the sheared and altered sediments, and in hairline fractures cutting primary laminations. Analyses*: Sample AB-87-43: 220 Au ppb, nil Ag ppm, 103 Cu ppm, 66 Pb ppm, 29 Zn ppm, 13 As ppm. Sample AB-87-44: 3570 Au ppb, 0.7 Ag ppm, 81 Cu ppm, 65 Pb ppm, 25 Zn ppm, 120 As ppm. Sample AB-87-45: 8500 Au ppb (8160 Au ppb), 1.0 Ag ppm, 50 Cu ppm, 53 Pb ppm, 53 Zn ppm, 95 As ppm. Sample AB-87-46: 4590 Au ppb, 0.9 Ag ppm, 118 Cu ppm, 31 Pb ppm, 26 Zn ppm, 47 As ppm. Sample AB-87-47: 450 Au ppb, nil Ag ppm, 75 Cu ppm, 22 Pb ppm, 25 Zn ppm, 15 As ppm. Sample AB-87-48: 20 Au ppb, nil Ag ppm, 39 Cu ppm, 15 Pb ppm, 23 Zn ppm, 10 As ppm. Sample AB-87-49: 3150 Au ppb, 0.6 Ag ppm, 183 Cu ppm, 48 Pb ppm, 19 Zn ppm, 25 As ppm. Sample AB-87-50: 5690 Au ppb (5420 Au ppb), --- Ag ppm, --- Cu ppm, -- Pb ppm, -- Zn ppm, -- As ppm. Sample AB-87-51: nil Au ppb, nil Ag ppm, 13 Cu ppm, 19 Pb ppm, 24 Zn ppb, 5 As ppm, Sample AB-87-52: 4050 Au ppb, 0.7 Ag ppm, 87 Cu ppm, 26 Pb ppm, 39 Zn ppm, 12 As ppm, Sample AB-87-54: 30 Au ppb, nil Ag ppm, 35 Cu ppm, 31 Pb ppm, 42 Zn ppm, 5 As ppm, * All assays performed by Swastika Laboratories Ltd., Swastika.

Alteration Comments

Dec 07, 2005 (R Degagne) - The discontinuous quartz veins on which the shaft is sunk are exposed intermittently in the detritus-filled trench and may be seen on the shaft walls. They are confined exclusively to the shear, and consists of narrow (1-10 cm wide) blue-grey quartz-actinolite stringers and pods hosted by rusty weathering sheared, dolomitized, sericitized, silicified and mildly sulphidized sediments. Muck samples obtained by the present writer from the waste pile on the shaft outcrop indicate that the quartz vein material is hosted by sheared, and pervasively carbonatized (Fe-dolomite), sericitized, and silicified sediments which have been subsequently fractured and nonpervasively carbonatized (calcite).

Geologist: R Degagne

Notes: Visited by A. C. Bath in 1987 All samples collected by the present writer were selected dump grab samples except one (AB-87-43) which was a trench chip sample taken across the trench about 3 m southwest of shaft. All assayed samples which contained quartz (with or without actinolite) vein material returned highly anomalously elevated gold values ranging from 3100 to 8500 ppb of gold. Samples devoid of vein material returned values ranging from nil to 450 ppb of gold, with a single sample of essentially unaltered wacke taken near the Matachewan diabase dike about 65 m from the shaft returning 30 ppb of gold. Silver (values less than 70 ppb), zinc (values less than 50 ppm), and arsenic (values less than 120 ppm) were uniformly low, regardless of whether or not vein material was present in the analyzed sample. The zone hosting the auriferous quartz veins is a narrow shear hosted by bedded turbiditic metasediments. Alteration associated with the shear is confined to it and consists of pervasive sericitization, Fe-dolomitization, silicification, and weak sulfidation. Although alteration effects are confined to the shear, a well developed fracture cleavage oriented subparallel to the shear marginal to it may assist in locating similar shears in the area. The occurrence is notable for the subtlety of its sulphide mineralization and for the gold values associated with quartz vein material. Also noteworthy is the presence of the Abitibi olivine diabase dike which subcrops northeast of the shaft outcrop. A magnetic survey of the area clearly indicates that this dike continues to the southwest (trending subparallel to the mineralized shear) and subcrops a few tens of metres north of the shaft. The relationship between this dike and the subparallel striking but northwest dipping shear which hosts the auriferous quartz veins has not been established.
