Jul 06, 2022 (Q Unknown) - Best assay: 0.24 opt au over 0.5 ft. Type of zone: porphyry-mafic contact rather than main zone quartz vein. The 1987 diamond drill programme on Novamin's Tabor Lake property outlined a quartz feldspar porphyry of some 167.6 metres in strike length. This porphyry is the host of numerous quartz veins and veinlets which are known to carry gold values on occasion. In the 1987 drilling, only hole 87-1 intersected a distinct quartz vein - known as the "Main Vein" - whereas all other holes failed to intersect auriferous quartz veins. Hole 87-4 intersected a contact zone between porphyry and mafic pillow lava's which assayed 0.24 oz/ton Au over 0.15 metre. A total of 595.6 metres of AQ core was drilled by Fontaine Diamond Drilling of Kenora, in 6 holes. All 6 holes intersected the quartz feldspar porphyry, being the potential host of quartz veins and quartz veinlets, which may carry gold values. The drilling was conducted in an area southwest, south and southeast of the shaft covering a 167.7 metre strike length of quartz feldspar porphyry (i.e. from 30° west to 2.5° east, with the "0" reference line running through the shaft in north-south direction - 04.5° magn.). For the sake of consistency, the author refers frequently in his 1987 core descriptions, to A.W.Beecham's 1985 drill logs as Beecham's observations and detail are excellent. The 1987 diamond drill programme, consisting of 6 holes for a total 595.6 metres, on Novamin's Tabor Lake property, outlined a quartz feldspar porphyry dike or sill of some 167.6 metres of strike length: this feature is still open to the west, east and at depth. This quartz feldspar porphyry is the host of numerous quartz veins and veinlets with potential gold values. Only hole TAB 87-1 intersected the "Main Vein" between 36.9 m and 37.1 metres with minor specks of galena (assay result 0.04 oz/ton Au); all other holes failed to intersect or delineate a distinct Main or principal auriferous vein. As such, the assay results of the 117 samples taken from these drill holes were not very encouraging: a notable exception is the 0.24 oz/ton Au over 0.15 m core length, obtained from the contact zone of porphyry and pillow lava, hole 87-4 @ 50.3 metres. As much of the porphyry is covered by overburden and as this feature is still open to the west and to the east, further delineation of this structure is recommended.
