Geology Comments

Dec 19, 2006 (Mark Puumala) - The dominant structural feature of the Pickle Crow area is a broad northeast-trending zone containing numerous shear zones and areas of extensive carbonatization (Stott 1996). Gold mineralization is commonly associated with these individual shear zones. On the Pickle Crow property, MacQueen (1987) has noted for distinct generations of deformation. The earliest structures (D1) are rarely-observed isoclinal folds that have been refolded by a second, more easily observed (D2) deformation event. The D2 deformation is represented by a northeast-striking penetrative axial planar schistosity (S2) that is subparallel to stratigraphy and dips steeply (75 to 87 degrees) to the northwest. The D2 schistosity is axial planar to F2 folds that are outlined by banded iron formations and reversals in younging indicators in the pillowed volcanic flows. The F2 folds that have been identified in the area include the Pickle Crow Anticline, Pickle Crow Syncline, Sawmill Anticline and Powder House Anticline. Two distinct sets of D2 shear zones have been noted by MacQueen (1987). These include Type 1 shears that are parallel to S2 surfaces, and discrete Type 2 shear zones that splay off the Type 1 shears. The Type 1 shears are described by MacQueen (1987) as northeast-striking strongly-foliated zones greater than 30 m wide that dip steeply (75 to 85) to the northwest. Type 1 shear zones identified in the Pickle Crow area include the Pickle Crow Fault, Highland Crow Shear Zone, Pumphouse Shear Zone and Powderhouse Shear Zone. The Type 2 shears strike east-northeast, and are described by Stott and Brown (1986) as shear zones formed at a low angle (Typically 15 degrees) to the principal flattening schistosity (i.e. S2). Stott and Brown (1986) also note that these shears commonly contain asymmetrically-folded quartz veins whose orientations are consistent with rotation toward the flattening plane during a major shortening event. MacQueen indicates that the most significant gold-bearing quartz veins and iron formation sulphide replacement zones in the Pickle Crow area occur within Type 2 shears (e.g., the No.1, 2 and 5 veins) that are spatially associated with the Pickle Crow Fault and/or Highland Crow Shear Zone. A third generation of structures (D3) that has been recognized by MacQueen includes northwest and northerly-striking conjugate faults. The D3 faults cross-cut and displace earlier structures, and typically dip steeply to the northeast. These late structures commonly host undeformed veins, felsic dikes and lamprophyre dikes. A final generation of structures (D4) is indicated by MacQueen (1987) to be represented by northwest-striking en-echelon extensional fractures that host diabase dikes.

Lithology Comments

Dec 19, 2006 (Mark Puumala) - The rocks of Pickle Crow Mine property are dominated by mafic metavolcanics of basaltic composition (MacQueen 1987). These metavolcanics are intercalated with banded iron formation, gabbro and porphyry sills (McGregor 1993), while a thick succession of felsic to intermediate volcanics occurs in the southeast portion of the property (MacQueen 1987). All of these rocks are cross-cut in the mine area by biotite lamprophyre and felsic dikes, while granitic rocks of the Hooker-Burkoski Stock occur to the southwest. Proterozoic-age diabase dikes cross-cut all lithologies. Stott (1996) describes the mafic metavolcanic rocks of the Pickle Crow area as typically pillowed flows that have been extensively carbonatized and strongly deformed. The quartz feldspar porphyry sills that intrude the mafic metavolcanics are described by Stott (1996) as lenticular bodies containing 3-5 mm quartz and feldspar phenocrysts within a fine- to medium-grained matrix. These intrusions generally conform to schistosity, and are often strongly-sheared. The iron formation units are described by Stott (1996) as magnetite-chert iron formation with interbedded greenish mudstone and local graphitic schist. The mudstone and graphitic schist interbeds are extensively ferroan dolomitized in the vicinity of Central Patricia and Pickle Crow (Stott 1996). This alteration has been noted to be spatially associated with the carbonatized mafic metavolcanics. The felsic to intermediate volcanic unit to the southeast is described by Stott (1996) as a lenticular, 2.6 m wide body of rhyodacitic to dacitic tuff and lapilli tuff to tuff breccia. The Hooker-Burkoski Stock is a quartz-phyric, biotite, sodic trondjemite (Stott 1996). Young (2003) has subdivided the supracrustal rocks of the Pickle Crow area into two distinct tectonic assemblages. The mafic metavolcanic-dominated sequence to the northwest has been assigned to the >2860 Ma Pickle Crow assemblage, while rocks to the southeast that include the intermediate fragmental units have been assigned to the <2741 Ma Confederation Assmblage. The approximate age of the Pickle Crow Assemblage has been inferred from a U-Pb age determination of approximately 2860 Ma obtained from a quartz porphyry sill in this area (Stott 1996). The base of the southeast-facing Confederation Assemblage is interpreted by Young (2003) to unconformably overlie the northwest-facing Pickle Crow assemblage immediately to the east of the former No. 1 shaft, with the base of this assemblage considered to be a unit of fragmental volcanics. A dacitic lapilli tuff from this assemblage that is located immediately south of the Pickle Crow area is reported by Young (2003) to have provided a U-Pb age of approximately 2729 Ma.

Mineralization Comments

Mar 30, 2017 (Andrew Tims) - Hole PC-16-306 intersected 1.28 g/t over 12.70 metres including 15.14 g/t over 0.70 metres in the middle vein zone of the No. 15 Vein.


Dec 19, 2006 (Mark Puumala) - MacQueen (1987) identifies five styles of gold mineralization in the Pickle Crow mine area . These include: 1. High-grade gold-bearing quartz veins occupying ENE-striking shear zones that cross-cut strata at low to moderate angles. Examples include the No. 1, 2 and 5 Veins. 2. Low-grade gold-bearing veins that occupy northeast-striking Type 1 shear zones that are approximately parallel to stratigraphy. The Albany Shaft shear veins are an example of this type of mineralization. 3. Stockwork auriferaous quartz veins in porphyry or gabbro intrusions that are contained within or are spatially associated with the ENE-striking shear zones. The ABC Zone is an example of this type of mineralization. 4. High-grade auriferous veins in NW-trending fractures that commonly splay off ENE-striking shear zones. The No. 9 Vein is an example of this type of mineralization. 5. Stratabound auriferous sulphide zones within iron formation adjacent to ENE-striking shear zones. Examples include the No. 1 and No. 5 Iron Formation Zones, and the Central Patricia Gold Mine. The most significant gold mineralization on the Pickle Crow property is hosted by the ENE-striking shears. MacQueen (1987) indicates that mineralization in the No. 5 vein (which is typical of veins hosted in ENE-striking shears) is localized in an approximately 100 m strike-length portion of the No. 5 Shear Zone where it cross-cuts banded iron formation and magnetite-rich basalt. The mineralized ENE-striking shears are typically 2 to 5 m wide, strike east-northeast, and dip 60 to 70 degrees to the north. The shears have strike lengths of up to 500 m and connect with larger northeast-striking shears. Most of these shears are also folded into asymmetric Z-folds. Although most of the gold mineralized veins are hosted within mafic metavolcanics or banded iron formation, gold mineralization also is known to occur in veins/shears that cross-cut porphyry intrusions and clastic metasedimentary rocks. The Arsenide Zone is an example of mineralization hosted within argillaceous and conglomeratic metasedimentary rocks (Winter 1987). Mineralization in this zone is characterized by pyrite and arsenopyrite. The gold mineralized veins at Pickle Crow consist of >95% quartz, with significant ankerite and calcite, and minor sericite, chlorite, tourmaline, scheelite, siderite, pyrite, pyrrhotite, arsenopyrite, chalocopyrite and free gold (MacQueen 1987). Gold also occurs within stratabound sulphide replacement zones where ENE-striking shear zones cross-cut banded iron formation. The sulphidized iron formation is reported by MacQueen to contain pyrite and minor amounts of pyrrhotite, arsenopyrite and chalcopyrite. Gold occurs either within the sulphides or in close association with them. The mineralized iron formation is reported by MacQueen (1987) to be surrounded by an alteration halo consisting of intense ankeritization of iron formation and the adjacent basalts. Due to the complex geological structure of the Pickle Crow area and the close association between mineralized shear zones and iron formation, historic gold production from the Pickle Crow mine property occurred from a number of different vein systems. The bulk of the historic gold production is reported by McGregor (1993) to have been obtained from the No. 1, 2, 5, 6 and 9 vein systems, with approximately 15 others having contributed ore. Total production from the Pickle Crow mine between 1935 and 1966 was 1,446,214 ounces of gold and 168,757 ounces of silver from 3,070,045 tons of ore (McGregor 1993). Although gold production on the Pickle Crow property ceased in 1966, substantial gold reserves are reported to remain in a number of mineralized zones. McGregor (1989) provides the following reserve estimates for 13 separate ore zones accessible from the existing No. 1, No. 3 and Albany shafts.


Aug 27, 2015 (Therese Pettigrew) - Two bulk samples were taken from the property by Cantera between Dec 1999 and Dec 2000. The first bulk sample was taken from the No. 5 Vein and sent to the St. Andrews Goldfields mill in Timmins, Ontario and the second, from the No. 1 Vein, was processed at the Golden Giant mine in Hemlo, Ontario. The first sample was comprised of 417.72 t at a head grade of 19.18 g/t Au with a recovery of 99.4% for 245.84 oz Au recovered. The second sample was comprised of 4,427 t at a head grade of 14.60 g/t Au with a recovery of 98.2% for 2,167.65 oz Au recovered. Some notable assay results include the following: PC-08-007: 30.10 g/t Au from 104-105 m; PC-08-010: 16.25 g/t Au from 128.5-129 m and 13.15 g/t Au from 133.3-133.81 m; PC-08-014A-W01: 52.7 g/t Au from 956-956.6 m and 31.9 g/t Au from 982.15-182.65 m; PC-09-014A-W04A: 56.3 g/t Au from 747.4-747.8 m; PC-09-052A: 134.26 g/t Au from 1139.8-1143 m including 838.14 g/t Au from 1140.3-1140.8 m; PC-10-052-W02: 138.89 g/t Au from 539.48-543.48 m including 299.1 g/t from 540-540.48 m; PC-10-059: 41.25 g/t Au from 135.6-135.9 m; PC-10-084-W02: 135.37 g/t Au from 595.9-596.4 m; PC-10-088: 37.57 g/t Au from 592-592.5 m; PC-10-095-W03: 21.34 g/t Au from 785.67-786.26 m (Hennessey et al., 2011). Scheelite was found in the ore (Jolliffe, 1942, p. 26), and in 1942 some 4,000 pounds of scheelite-bearing material was hand-picked from the sorting belt. Concentration of this material on a table installed for the purpose yielded 120 pounds of tungsten concentrate (Little, 1959).

Geologist: Mark Puumala

Notes: The No. 1 vein system, which was observed in surface exposures on July 18, 2007, is largely mineralized where it cross-cuts an iron formation horizon. The iron formation strikes approximately 060, while the No. 1 vein system is associated with an approximately 072-striking shear zone that dips steeply toward the north. Quartz veining within the shear zone is irregular, consisting of contorted veinlets and pods. The iron formation within the shear zone is contorted and folded, with fold hinges plunging steeply toward the east. The iron formation has also been sulphidized to a significant extent.
