NI 43-101 Update (September 2012): 11.1 Mt @ 1.68% Ni, 0.87% Cu, 0.89 gpt Pt and 3.09 gpt Pd and 0.18 gpt Au (Proven & Probable Reserves) / 8.9 Mt @ 1.10% Ni, 1.14% Cu, 1.16 gpt Pt and 3.49 gpt Pd and 0.30 gpt Au (Inferred Resource)
Perhaps someone can decipher as to what we can expect from these holes and which ones are step outs. TIA !
Hole NOT-07-20 was drilled at local grid collar location 50+83E at 10+50N with an initial azimuth of 270 degrees and an initial dip of -61 degrees to undercut hole NOT-07-19. After a few meters of overburden and limestone the hole entered granodiorite at 12 meters, then went into peridotite at 17.2 meters and then in and out of peridotite and olivine gabbro dikes until 48.6 meters. At 48.6 to 103.8 meters the hole entered weakly mineralized peridotite, followed by another mafic dike between 103.8 and 113.9 meters. Then, well mineralized peridotite was encountered between 113.9 to 125.1 meters. Another mafic dike was encountered to 128.2 followed by granodiorite to the end of the hole at 144 meters.
Hole NOT-07-21 was drilled at local grid collar location 50+83E at 10+50N with an initial azimuth of 270 degrees and an initial dip of -73 degrees to undercut hole NOT-07-20. Similarly to hole 20, this hole encountered the same set of olivine gabbro dikes and peridotite between 11.7 and 35.0 meters downhole, then a weakly mineralized to barren peridotite was encountered to 144 meters. Well mineralized peridotite was encountered between 144 and 162 meters with a short felsic dike between 150 and 151 meters. Then semi-massive sulphides were encountered between 162 and 173.8 meters followed by weakly mineralized peridotite to 174.8. A mafic dike was then intersected between 173.8 and 184 meters, followed by granodiorite to end of this hole at 183 meters.
Hole NOT-07-22 was drilled at local grid collar location 51+21E at 10+10N with an initial azimuth of 270 degrees and an initial dip of -62 degrees. The hole entered granodiorite at 13.5 meters to 154.7 meters. At 154.7 the hole entered a strongly deformed and brecciated unmineralized peridotite and remained in this rock unit until 209 meters when it entered olivine gabbro. At 215.8 a barren peridotite was encountered to 222.4 then a short massive sulphide section was encountered to 223.5 meters (only 1.1 meters thick). Peridotite with minor sulphides were encountered until 244.5 then granodiorite was encountered to end of hole at 258 meters. This hole is interpreted as having just caught the bottom of the southerly plunging zone at a vertical depth of 200 meters.
Hole NOT-07-23 was drilled on local grid collar location 51+08E at 10+80N with an initial azimuth of 269 degrees and an initial dip of -78 degrees. After passing through 5.5 meters of overburden and limestone, this hole immediately entered peridotite (with a felsic dike) until 228.2 meters, when the hole entered granodiorite until 241.1 meters. The hole then went back into a mineralized peridotite until 224.4 then into semi-massive sulphides between 242.4 and 243.2 meters after which the hole entered granodiorite until it was terminated at 293 meters. This hole along an E-W section 37.5 meters north of hole NOT-07-22, also has been interpreted as encountering the bottom of the southerly plunging zone at a vertical depth of 235 meters.
Hole NOT-07-24 was drilled on local grid collar location 51+74E at 10+65N with an initial azimuth of 270 degrees and an initial dip of -42 degrees, designed to undercut discovery holes NOT-07-01 and 02. After passing through overburden, limestone to a depth of 16 meters the hole entered granodiorite and stayed in this rock unit until 65.4 meters when the hole encountered a mafic dike until 76.3 meters. The hole then reentered granodiorite until 83.1 meters. An olivine rich gabbro was then encountered between 83.1 and 100.4 meters. Barren peridotite was encountered between 100.4 until 119 meters downhole. Then mineralized peridotite to 140 meters, then net textured mineralized peridotite was encountered between 140 meters and 187.8 meters followed by a 2.7 meter wide massive sulphide section until 190.7 meters downhole for a total mineralized zone width of 71.7 meters. The hole then entered a contact zone with the granodiorite and peridotite, in and out of granodiorite, ending in granodiorite between 220 and 233 meters.
Hole NOT-07-25 was drilled at local grid collar location 49+55E at 12+22N with an initial azimuth of 102 degrees and an initial dip of -46 degrees. This hole entered granodiorite at 18 meters then went into a mafic dike between 43 meters and 52.3 meters then back into granodiorite with numerous mafic dikes and felsic dikes until 252.7 meters. Highly altered peridotite (to serpentinite) was encountered between 252.7 meters and 277.8 meters. The hole went in and out of peridotite and mafic dikes until 301.5 meters. At 301.5 granodiorite was encountered and the hole was stopped at 307 meters. This hole is believed to have deviated severely southwards not encountering the peridotite intrusive until 252.7 meters as opposed to the expected down hole depth of 180.0 meters. With the exception of minor copper mineralization in the hanging wall granodiorite the hole encountered no visible sulphide mineralization to the end of the hole at 307 meters. Downhole surveying must be awaited before the actual location of this hole can be determined.
Hole NOT-07-26 was drilled at local grid collar location 51+74E at 10+69N with an initial azimuth of 270 degrees and an initial dip of -52 degrees. This hole encountered drilling problems due to faulty equipment downhole and was lost at 75 meters, well short of the intended target. Hole NOT-07-26 was restarted as Hole NOT-07-28 from the same collar location at -51 degrees, and is still underway.
