Subprovince: Wabigoon
Terrane: Eastern Wabigoon
Belt: Onaman-Tashota
Geological Age: Archean
Dec 07, 2005 (B Nelson) - The Kenty property is underlain by massive, altered and recrystallized mafic flows and tuffs of the Tashota-Onaman Metavolcanic Belt. Sheared mafic tuffs are interbanded with quartz feldspar porphyry dykes. Large euhedral to subhedral pyrite cubes occur along shear planes striking 057 degrees to 065 degrees. A crenulation cleavage is well displayed in the mafic tuffs. Quartz veining on the east end of the property (striking 085 degrees) is associated with a biotite lamprophyre intruding the mafic metavolcanics. Quartz can be vitreous or saccharoidal and pyrite is hosted in the quartz. The mineralized zone extends east and west with the schistosity strike. The dip is nearly vertical. Recrystallized greenstone bounds the mineral zone on the north; on the south, the mineralization can be traced to where the rock is covered by muskeg. The mineralization was no doubt produced from solutions coming from the granite. Some quartz veins up to 0.9 m in width lie on the north side of the mineralized belt.
Feb 23, 2021 (Therese Pettigrew) - The showing is located within the eastern sector of the Humboldt Bay Deformation Zone (HBDZ) as part of a 25 kilometer trend. It is proximal to the intersecting Onaman Lake Shear. The rocks underlying the property are part of the Willett Assemblage (ca. 2740 Ma) which is characterized by massive to pillowed mafic flows (high-iron to magnesium-rich tholeiitic and calc-alkaline basalts) in the southeastern domain of the Wabigoon Subprovince of the Superior Province. Inter-formational clastic and lean BIF occur within the mafic metavolcanics, intruded by a variety of syn and post-volcanic felsic to intermediate intrusives, including feldspar and quartz-feldspar porphyries (Assessment report 20000007595).

Dec 07, 2005 (B Nelson) - A narrow sequence of intermediate felsic metavolcanics outcrops west of the Kenty property and consists of feldspar porphyry, quartz porphyry and breccia. Intruding the metavolcanics is a small porphyritic quartz monzonite-granodiorite complex immediately southeast of the 8 leased claims. The Castlewood Lake Intrusion outcrops 7.6 km south of the prospect and is a large sub-circular diorite-gabbro body. Two small lenticular gabbro units intrude the mafic metavolcanics northwest of the Castlewood Lake Intrusion.

Dec 07, 2005 (B Nelson) - Some quartz veins up to 0.9 m across lie on the north side of the mineralized belt. Channel samples taken across 2.4 m to 3 m of mineralized schist carried values ranging from $4 to $14 in gold per ton (at a 1924 Au price of $20.79/oz). Grab samples collected in 1985 returned results of no more than 0.01 oz/ton Au.
Feb 23, 2021 (Therese Pettigrew) - Upon discovery of two showings by the Kenty Brothers in the Conglomerate Lake area in 1924, there was follow-up prospecting, sampling, and blast trenching over a period of five years, until 1929. Results from sampling varied from 6.63 g/t Au to 23.2 g/t Au across 2.4 to 3.05 meter widths in what is now called the Centurion Zone (Kenty North) and Leopard Zone (Kenty South). In 1986, Andaurex Resources reported 2.06 g/t Au over 6.1 m and 5.48 g/t Au over 1.5 m from the Leopard Zone in Holes 1, and 9.93 g/t Au over 1.5 m and 34.9 g/t Au over 3.05 m from the Centurion Zone in Hole 2. In 2009, Kodiak collected grab samples that returned up to 2.2, 3.1, 7.25 8.09, and 37.6 g/t Au from the Centurion Zone. Channel samples taken over the Centurion Zone returned up to 6.94 g/t Au over 1.45 m. The Leopard Zone returned channel sample results up to 1.48 g/t Au over 7.85 m and grab samples of up to 22.9 g/t Au. DDH CWL10-02 returned 6.75 g/t Au over 1 m from a graphitic argillite. DDH CWL10-06 returned 5.21 g/t Au over 1 m from the Leopard zone. DDH CWL10-07 returned up to 1.86 g/t Au over 11.4 m including 4.73 g/t Au over 3.4 m from the Leopard zone. DDH CWL10-08 returned 1.2 g/t Au over 5.05 m including 6.77 g/t Au over 0.6 m from the Centurion Zone (Assessment report 20000007595).
Dec 07, 2005 (B Nelson) - Metavolcanics have been silicified and carbonatized. Portions of the schist are silicified.
