The Jasper 1 showings are located between Caycuse Creek and Jasper Creek 7 kilometres northeast of the north end of Nitinat Lake. The showings were previously staked as the TAM claims between 1971 and 1975. The TAM 16 (092C 081) showing occurs about 900 metres south of the Main showing.

The area is underlain by mafic to felsic volcanics, breccia, tuff and siltstone of the Lower Jurassic Bonanaza Group. The rocks have undergone faulting and shearing. The Main showing is hosted in chloritized mafic volcanics near the contact with a rhyolite flow complex.

The Jasper 1 showing comprises 3 occurrences. Three styles of sulphide mineralization are present: 1) massive 2) fracture-filling and 3) disseminated.

The Main showing, exposed in a road cut over 30 metres near the centre of the claim, comprises several small fracture controlled wedges of massive sulphides separated by weakly mineralized silicified and kaolin altered mafic volcanic rock. Individual zones are up to 2 metres long and 50 centimetres wide comprising 80 to 90 per cent pyrite, 5 to 20 per cent sphalerite, 1 to 5 per cent chalcopyrite and trace galena. The Main showing is located at the intersection of two fracture systems which display intense fracturing, alteration, pyritization and quartz-stockwork development. Sulphides appear to have filled narrow, irregular fractures that were subsequently faulted and commonly display a crude banding which is locally brecciated and cut by a quartz stockwork. Epidotization and hematization of the mafic and, to a lesser extent, the felsic volcanic rocks is common. Chloritization is rare except in the chlorite breccia unit. The best drill intersection was across 1.34 metres grading 1.65 per cent copper, 3.52 per cent zinc and 6 grams per tonne silver (Assessment Report 17105). In 2004, a selected float grab sample from the main showing assayed 7.83 per cent copper, 37.0 grams per tonne silver and 0.037 grams per tonne gold (Assessment Report 27657).

In the area, medium grained pyrite, sphalerite and chalcopyrite occur within fractures up to 2 centimetres wide and 10 centimetres long. A grab sample from one of these assayed 0.61 per cent copper and 1.3 per cent zinc (Assesment Report 17105). Disseminated sulphides occur as pyrite in fracture zones and chalcopyrite and sphalerite related to massive or fracture-filling sulphides.

South of the Main showing, about 500 metres, pyrite, sphalerite and chalcopyrite occur in fractured intermediate volcanic rocks. To the north, 175 metres, pyrite and chalcopyrite occur in similar rocks. A quartz breccia gold vein is reported to occur about 300 metres southwest of the Main showing. A rock chip yielded 19 grams per tonne gold from this vein (Assessment Report 24716).

South west of the Main showing, approximately 400 metres, a 100 meter long, steeply dipping, northeast-striking outcrop of massive felsic volcanics, interpreted to represent a rhyolite dome, containing

hematite-altered breccia fragments, limonitic box work textures along fractures, and 2 per cent fine grained disseminated sulphides. In 2004, a sample (105410) from the zone assayed 0.003 per cent copper, 0.026 per cent lead, 0.191 per cent zinc and 0.3 grams per tonne silver over 5 metres (Assessment Report 27657).

All occurrences located on the property, except one, are localized within the elongate fracture zones.

The Jasper property consists of three MINFILE occurrences known from north to south as the Jasper 1 (092C 080), Tam 16 (092C 081) and the Pan (Easy)(092C 088). The Tam and Easy properties were previously staked by Hudson Bay Mining and Smelting who conducted geological mapping, soil and rock geochemistry and an induced polarization (IP) geophysical survey in 1970 and 1971. Also in 1971 , Marshall Creek Copper conducted and extensive soil sampling survey on the Pan (Easy) and Tam properties. In 1980 and 1981, Malibar Mines conducted soil sampling on the Jasper property. In 1984, a prospecting program was carried out by Ron Bilquest. Falconbridge followed in 1985 by conducting a geological, soil and VLF-electromagnetic program. Asamara then conducted a brief geology, soil and electromagnetics survey in 1987. The property lapsed and was relocated by Arne Birkeland in 1994. Geological mapping and sampling consisting of 39 rocks, 40 silts and 133 soils was carried out. A geological and geochemical progam was completed in 1995. The property was optioned to Consolidated Taywin Resources Inc. (later renamed Inspiration Mining Corporation) in 1995 and from December 1995 to June 1996, a work program was carried out consisting of 84 soil samples, a 1.2 kilometre IP survey, a 3 kilometre VLF and Horizontal Loop survey and a 2.1 kilometre ground magnetics survey. During 2000 through 2003, Inspiration Mining Corp. completed various programs of soil, moss mat, stream sediment and rock chip sampling on the Jasper Property, primarily on the Pan (092C 088) occurrence. This work extended the 1998 grid to the north and south and identified numerous polymetallic geochemical anomalies associated with gossanous alteration zone over a strike length of 1.6 kilometres. In 2004, programs of soil and stream sediment surveys and rock sampling were completed on the property. A ground VLF-EM and magnetometer survey was completed on the Jas and Pan grids. In 2007, a 4-sample geochronology sampling and analysis program was completed, suggesting a possible Jurassic age for the sulphide mineralization. In 2008, Inspiration Mining completed a program airborne electromagnetic and magnetic geophysical surveys, totalling 817.9 line-kilometres. In 2010 and 2011, Nitinat Mineral Corp. completed programs of geochemical sampling, prospecting, geological mapping and trenching on the Jasper property.
