Nov 30, 2015 (C Salo) - Geological mapping indicates that the multiple discrete gold deposits delineated by Clavos Porcupine Mines/Canamax Resources/Bruneau Mining in northern German and Stock Twps are spatially associated with the Pipestone Fault Zone (PFZ). The PFZ occurs at or is closely associated with the contact between east striking, steeply dipping, and north facing weakly metamorphosed (greenschist or lower metamorphic facies) clastic sedimentary rocks and volumetrically minor intercalated volcanic rocks of the (Archean) Porcupine Group (to the south) and east striking, steeply dipping and north facing subaqueously deposited felsic to ultramafic volcanic rocks of the (Archean) Stoughton-Roquemaure Group (to the north). Intrusive rocks in the area include mafic to felsic bodies and dikes which intrude Stoughton-Roquemaure Group rocks north of the PFZ, and (ubiquitous), as revealed by exploration diamond drilling and a recent geophysical survey of the area narrow (tens of meters in width) north striking dikes of the (Proterozoic) Matachewan swarm. Glaciofluvial deposits in the area are thick, complex, and mantle virtually all bedrock.

Nov 30, 2015 (A Wilson) - The mineralization at Clavos is located within an envelope of highly altered ultramafic flows and volcaniclastic fragmental rocks referred to as the DL zone. The DL zone, which lies approximately 10 m north of the sedimentary-volcanic contact, varies in thickness from 30 metres to 60 m, is cored by several semi-concordant, east-west trending, steeply dipping and shallow east-plunging feldspar porphyry bodies of up to 20 m in thickness. The shallow easterly plunge is regional in character and is overprinted by local structures. Three distinct types of intrusive rocks controlling the gold mineralization have been identified, consisting of feldspar porphyry, quartz-feldspar porphyry, and intermediate to mafic intrusive. They occur primarily within the DL alteration envelope, less commonly within the sedimentary and talc-chlorite ultramafic rocks. The feldspar porphyry type is generally grey-green, with vague one millimetre to five millimetre white feldspar phenocrysts in a fine-grained groundmass of feldspar and chlorite. These porphyries occur as narrow dikes or sills ranging from five centimetres up to six metres in core length, primarily within the hangingwall to central part of the DL zone and less commonly within the sediments. The feldspar porphyry is weakly to moderately foliated, typically has a grey tinge, with weak carbonate, and less commonly sericite or albite alteration. Hangingwall (HW) type veining is variably developed within the unit, ranging from 2% to 70%, and consists primarily of the quartz-ankerite type (less common quartz-albite), with styles varying from early grey, late white, extension, and stylolitic. The quartz-feldspar porphyry type varies dramatically in colour due to variable alteration. It ranges from apple green in sections of strong sericite to mottled grey-brown and pink-white in areas of strong silica and/or albite alteration. This type contains vague to well-defined one millimetre to three millimetre white feldspar phenocrysts and local one millimetre to three millimetre grey quartz phenocrysts in a very fine-grained intensely altered groundmass. It occurs as narrow dikes or sills ranging from 40 cm up to five metres in core length, primarily within the central to footwall part of the DL zone, less commonly within the sediments and talc-chlorite ultramafic rocks. The sericite alteration within the quartz-feldspar porphyry appears to be overprinted by variable moderate to strong silica and albite alteration, often with chlorite stringers. The Footwall (FW) Zone vein density ranges from 2% to 70%, and consists primarily of the quartz-albite type with the style dominated by late white extension veins or stockworks, with less common early grey and stylolitic vein styles. The intermediate to mafic type is generally grey-green, with wispy one millimetre to 20 mm mafic/chlorite clasts in a fine-grained groundmass of feldspar and chlorite. Locally it contains vague one millimetre to five millimetre feldspar phenocrysts. It occurs as narrow dikes or sills ranging from five centimetres up to three to four metres in core length, primarily within the footwall part of the DL zone. Veining is generally poorly developed within the unit, ranging from 2% to 5%, and consists primarily of the quartz-ankerite/calcite type, with the style dominated by the late white to grey extension veins. In general, the best veining within the DL alteration envelope occurs close to the contacts of all three intrusive types. Deformed early grey, ribbon or stylolitic veining, with pyrite and arsenopyrite in stylolites and near vein margins, appears to be related to the best gold values. The lens geometry of the HW and FW type mineralization in the 960 Zone appears to be controlled by a box fold hinge. The sediment/ultramafic contact reverses from north facing to south facing between the 1,150 m elevation and the 1,100 m elevation.
Dec 07, 2005 (C Salo) - The footwall rocks are ultramafic rocks of the Stoughton-Roquemaure Group, largely composed of dark green, medium-grained, talc-bearing serpentinized peridotite and/or komatiitic flows. The pseudo-fragmental units are strongly foliated and appear to be composed of buff brown and light grey, fine-grained, flattened angular fragments within a chlorite-rich matrix. Core samples resemble flattened lapilli or sedimentary clasts. Fragments are generally less than 2 or 3 cm long and 0.5 cm wide. Thin section examination shows the fragments to be aggregates of fine-grained carbonate and few fine, irregular quartz and feldspar grains, with a smaller percentage of chlorite and minor sericite. The matrix consists of chlorite and minor sericite. Chlorite imparts a strong foliation throughout the rock, both in the fragments and matrix.

Nov 30, 2015 (A Wilson) - Assays from diamond drilling completed by Clavos Porcupine returned values of $5.09 Au over 9.2 ft., $7.86 Au over 12.9 ft. The best intersections obtained from the 1984 Canamax drilling on the Discovery Zone were 9.9 g/t Au over 12.8 m and 6.9 g/t Au over 5 m. There are five gold-bearing zones for which mineral resources have been estimated. These are the Hangingwall Zone (HW Zone), the Footwall Zone (FW Zone), the Contact Zone, the Sediment Zone, and a group of miscellaneous intersections listed as Other Mineralization. Of these zones, the HW Zone has been the main target of past mining activities. The HW Zone and FW Zone represent the majority of the mineralization at Clavos and vary from 1.5 m to more than 3.0 m in horizontal thickness along the south and north contacts of the feldspar porphyry bodies respectively. These zones consist of quartz and quartz-carbonate veins and stringers hosted within a sulphide-rich package of fuchsite and sericite altered ultramafic volcanic rocks. Up to 10% sulphides consisting of pyrite, arsenopyrite, galena, gersdorffite (nickel arsenide), and rarely chalcopyrite occur as disseminated grains inthe altered host rock and within narrow fractures/veinlets within the quartz veins. Gold occurs as coarse nuggets predominantly within the quartz veins but occasionally within the volcanic host, and also as inclusions within the sulphide grains.
Nov 30, 2015 (C Salo) - At the site of the original Clavos Porcupine Mines discovery (about 300 m east of the Discovery Zone, sign. anomalously elevated Au tenors were intersected several hundred feet south of a strong fault (the Pipestone Fault) within silicified, carbonatized, and sulfidic (pyrite and arsenopyrite-bearing) bands within both tuff and sediment. Here, the highest Au tenors were described to occur within tuff, but significant Au tenors are apparently also associated with fine grained disseminated acicular arsenopyrite within ...bleached replacement zones in the greywacke near the sediment/volcanic rock contact. The discrete auriferous deposits are spaced at 300-500 m intervals along strike within the pseudo fragmental horizon. Each auriferous shoot may be comprised of multiple discrete auriferous horizons within multiple geologically distinct environments. The auriferous. deposits are consistently described to be associated with a steeply dripping quartz-carbonate vein system which is best developed within and marginal to a linear stratigraphic and PFZ subparallel porphyritic body or composite felsic unit which is hosted by tuffaceous (pseudofragmental) rocks south of the PFZ. Quartz-carbonate-tourmaline veins may be developed in the Porcupine Group sediments south of the auriferous zones, and these are generally not auriferous gold mineralization which was subsequently delineated by Bruneau/Canamax along the PFZ. Diamond drilling indicates that the systems with which the best gold tenors are discontinuously developed and locally crosscut stratigraphically, although on a deposit scale, they are oriented subparallel to stratigraphy and the PFZ. These vein systems also may or may not have developed marginal to them various types of alteration. Gold tenors at the Clavos deposit are proportional to arsenopyrite content, with the highest gold concentration occurring when arsenopyrite content is much greater than that of pyrite. The porphyry or felsic dike lithology is often anomalously auriferous (in some core sections consistently averaging about 1,000 ppb of Au) but is generally potentially economically exploitable only where it hosts quartz-carbonate veins.
