Jun 16, 2011 (N Bennett) - Over its history, Nortoba-Tyson property has seen 8,700 feet of diamond drilling, as well as extensive trenching and bulk sampling, and ground geophysics. The #1, #1A, #2 and #7 gold veins were partially evaluated and bulk samples totalling 135 tons from #1A vein yielded 139 ounces of gold averaging 1.03 oz. per ton (Geological Report 122, 1975 Mackasey, Ministry of Northern Development and Mines). However, the #3 vein received most of the attention because of its high-grade molybdenum content. An assessment by A.E. Tyson in 1959, concurred with by Dr. E.G. Pye for the Ontario Department of Mines, outlined a possible reserve of 72,000 tons averaging 1.73% MoS2 (equal to 1.04% Mo grade) over a 3.0 foot mining width to an initial depth of 375 feet. The zone is open at depth. A second, parallel zone was also intersected in some of the drilling approximately 75 feet to the south. It’s important to stress that these possible reserve estimates were calculated according to the standards of the time, which do not comply with National Instrument 43-101 and today would likely be considered inferred resources. Peter A. Bevan, an independent consulting geologist and a Qualified Person according to NI 43-101, has verified the estimate of 72,000 tons using available historical data. The Nortoba-Tyson gold and molybdenum system is parallel to and structurally related to Goldstone's Sand River/Leitch Mine gold project which is know to persist to depths in excess of 5,000 feet. Deep drilling will be required to assess the molybdenum veins' ultimate potential. (for more details – see the Technical Report on the Nortoba Tyson Molybdenite Property dated April 2006)
Feb 06, 2015 (Therese Pettigrew) - Vein # 7 zone consists of shearing zone containing a quartz vein. The width of the shear averages about 10' with the quartz vein reaching widths of 3'. Areas of the shear zone namely the east and west ends, contains irregular network of quartz stringers. The shear is carbonated and siliceous with both shear and quartz stringers containing minor pyrite with exception of the extreme west end where more abundant pyrite is found. The bulk of the quartz is located in the middle of the zone. Here the stringers become veins with parallel lenses of quartz. Mineralization consists mainly of pyrite with minor chalcopyrite and malachite staining with sulphides usually not exceeding more than 1 percent. The quartz is of the crack-seal variety, whitish in colour and contains sericite and chlorite alteration mainly along fractures. The strike length observed is about 450'. Assays from the 2003 prospecting program were poor, with values ranging from <0.001 to 0.022 oz/t Au. Vein #2 zone consists of a rusty shear zone up to 40 inches in width with a quartz vein reaching width with a quartz vein reaching a width of 24". In places along the zone the quartz divides into two veins with the carbonated, siliceous sheared volcanics in between. These veins separate for only a short distance then merge as one vein. At the extreme west end of exposure the vein again separates with about 10' of separation and a longer length until they seem to peter out in small stringers. The quartz matter varies from whitish, crack-seal, chlorite-sericite altered to cherry well-fractured. Both carry pyrite with lesser chalcopyrite with >1% sulphides. The strike length observed in this vein is about 650'. Assay returned values of 0.097, 0.134, 0.564 and 1.118 oz/t Au. Vein #1 zone consists of moderately fractured, whitish, crack-seal quartz reaching widths of 3' or more. The vein appears to follow a fault along which a somewhat rusty shear zone has developed. As in the other veins the country rock is coarse- to fine-grained andesite. The strike length observed is about 100'. Mineralization mainly consists of pyrite found only in minor amounts usually in chlorite fractures. Assay values range from 0.008 to 0.185 oz/t Au. Vein #1A zone is possibly a faulted off section of vein #1. It lies parallel and adjacent to vein #1. It has been exposed in an open cut roughly 60 feet long and 6 feet wide and shaped like a "V". Mineralization consists of pyrite and lesser galena, ranging from minor to massive. Again the sulphides for the most part are confined to chloritic fractures. Based on assay returns, the greater the mineralization, the higher the gold content. The vein reaches a width of roughly 2'. The bottom part of the "V" cut was unreachable manually because of debris including large boulders which had fallen from surface. Assay returned values of 0.272, 2.752 and 11.067 oz/t Au (AFRI 52H09NE2006).
