Point Location Description: Outcrop/stripped area

Location Method: Field Visit with GPS

Access Description: The Carlo part of the former Wilcarr Mines Ltd. property is in the north half of lot 2, concession 6, Carr Township and is most easily reached from northwestern Beatty Township via an ATV passable trail leading west from the Lady Maude Lake area into Carr Township. When visited by A. C. Bath in 1986, an overgrown and poorly marked 1.9 km long trail leading through heavy bush along the Carr Township lot 2/3 common boundary was followed. This trail may be reached via the north end of the lot 2/3 road, which intersects Highway 101 1.7 km east of Matheson. The outcrop is now crossed by a road extending north from Hwy 101 between lots 2 & 3 of Carr Township. A larger stripped area is located east of the road.

Geology Comments

Jan 19, 2016 (D Guidon) - The geology of the zone is exposed east of the road. The mineralization is hosted in a shear zone that is generally 2-3 m in width. The shear strikes at 285º and dips at 85º to the northwest. Mafic volcanic rocks are exposed to the northeast of the shear and possibly sedimentary rocks to the southwest. In the area of the stripping, the zone has been thickened, possibly by drag folding. This is suggested as the northern edge of the shear zone rolls to a strike of 250º, dipping 60º to the northwest. It is approximately 8 m wide and about 30 m long. Quartz stringers, up to 5 cm wide strike at 190º and dip at 80 degrees to the west. These veins are only within the shear zone and do not extend beyond into the surrounding rocks.

Jan 19, 2016 (R Degagne) - The sediments (bedrock metamorphic grades are greenschist or lower metamorphic facies) south of the contact belong to the (Archean) Porcupine Group, the volcanic rocks north of the contact belong to the (Archean) Stoughton-Roquemaure Group, and diamond drilling by Wilcarr Mines in the mid 1940's is reported to indicate that although locally sheared and intensively altered near the contact, both the sediments and volcanic rocks are part of a north dipping, north facing and east plunging assemblage. The contact relationship between these two Groups, furthermore, appears to be conformable. In the Beatty Township area, the metasedimentary rocks which comprise the Porcupine Group are represented by deep water facies turbiditic sediments and tuffaceous siltstone members while the Stoughton-Roquemaure Group volcanic rocks are represented largely by subaqueously deposited tholeiitic volcanic rocks, volumetrically less abundant komatiitic volcanic rocks, and (rarely) horizons of calc alkalic rhyolite and/or dacite, On the (former) Wilcarr Mines property, diamond drilling is reported to indicate that the Porcupine/Stoughton-Roquemaure Group contact (Contact) is gradational, with the upper part of the (underlying) Porcupine Group sediments represented by conglomerates which yield up section to tuffaceous sediments, agglomerates, and massive and pillowed volcanic flow rocks of the Stoughton-Roquemaure Group which contain only minor amounts of intercalated interflow sedimentary material. Closely associated with the Contact, and often (assessment files) immediately north of it is the Pipestone Fault Zone (PFZ), a regional scale arcuate structure that, in the Carr/Wilkie-Taylor/Walker-Stock/Clergue Township area is about 7 km north of and strikes subparallel to the Porcupine- Destor Fault Zone (PDFZ).

Lithology

Lithology Comments

Jan 19, 2016 (R Degagne) - On the (former) Wilcarr Mines property, diamond drilling is reported (assessment files) to indicate that the Porcupine/Stoughton-Roquemaure Group contact (Contact) is gradational, with the upper part of the (underlying) Porcupine Group sediments represented by conglomerates which yield up section to tuffaceous sediments, agglomerates, and massive and pillowed volcanic flow rocks of the Stoughton-Roquemaure Group which contain only minor amounts of intercalated interflow sedimentary material. In general, the PFZ is poorly known (except locally, where intersected by diamond drilling) due to extensively developed overburden cover. Drilling by Wilcarr Mines indicates (assessment files) that where this structure has been intersected by drilling: a) it is characterized by shearing and faulting oriented subparallel to the enclosing stratigraphy and often by the development of talc-chlorite schists; b) shearing is always localized along the contact, but may also occur completely within volcanic rocks to the north; c) Contact- distal shearing may be manifested as localized shearing confined to interflow horizons within the volcanic rocks; d) sheared and/or 'tuffaceous' rocks are usually carbonatized and may be cut by quartz-carbonate veinlets which may be auriferous; and e) talc-chlorite-serpentine schists along the Contact display variable thicknesses, ranging from less than 10 to more than 400 feet. Intrusive rocks in the area include an elongate stock of largely undeformed but variably carbonatized and sericitized 'albite granite' which is immediately north of the PFZ. This felsic stock contains characteristically 40% of modal albite and accessory amounts of apatite and tourmaline. Magnetic survey data and diamond drilling indicate that numerous narrow (tens of metres in width) diabase dikes of the north striking (Proterozoic) Matachewan swarm.

Mineralization

Mineralization Comments

Jan 19, 2016 (D Guidon) - On this outcrop, only 1 of the types of mineralization described by Bath (1990) are observed: auriferous quartz-carbonate-pyrite-arsenopyrite-chalcopyrite veinlets hosted by pervasively sheared and altered rock. The veins tend to be oriented at 190-80 although they are more randomly oriented in the thickened zone.

Dec 07, 2005 (R Degagne) - Four types of precious metal mineralization are known to occur on the (former) Wilcarr Mines property: auriferous quartz-carbonate-pyrite-arsenopyrite-chalcopyrite veinlets hosted by pervasively sheared and altered rock; auriferous quartz-carbonate-pyrite-galena veinlets hosted by variably carbonatized and sericitized sedimentary rock; auriferous quartz-carbonate-pyrite-arsenopyrite veinlets in sheared granitic rock; and auriferous quartz veins hosted by sheared carbonate. All mineralization types are spatially associated with the PFZ. Carlo-type (Type 1) mineralization is characterized by quartz- dolomite-pyrite-arsenopyrite-(chalcopyrite) veins and stringers within dolomitic and sericitic shears developed in pervasively carbonatized mafic volcanic and/or interflow sedimentary rock marginal to (known to occur up to several hundred metres from) the inferred position of the PFZ. Type 2 mineralization to consists of narrow systems of auriferous quartz-carbonate- pyrite-galena stringers hosted by significant (up to 240 feet in true width) thicknesses of variably carbonate- and sericite enriched Porcupine Group sediments up to several hundred metres from the inferred location of the PFZ. Type 3 mineralization consists of quartz-carbonate-arsenopyrite veinlets confined to narrow shears developed in pervasively microfractured, carbonatized and sericitized sodic felsic intrusive rock up to several hundred metres from the inferred position of the PFZ. Type 4 mineralization consists of 'low' gold values associated with quartz veins developed in sheared carbonate (which characterizes much of the PFZ). The coincidence of an AEM conductor with the location of the PFZ may also indicate the potential in the area for a graphite/gold association and/or base metal sulphide mineralization.

Alteration Comments

Jan 19, 2016 (A Wilson) - Bath reported assays up to 349 ppb gold and 9950 ppm arsenic from a grab sample in the trench and assays up to 2.43 ounces gold per ton are reported from the 1930s. Wilcarr Mines Limited did not encounter significant gold mineralisation in diamond drill holes in this area. Gold-bearing quartz-carbonate-pyrite-galena veins are reported to occur in carbonatized and sericitized metasedimentary rocks of the Hoyle assemblage. Gold assays up to 0.16 ounce gold per ton were reported by Wilcarr Mines Limited, however the veins proved to be erratic in distribution. Maude Lake Gold Mines Limited explored for these types of veins without success in 1986.
