The Kaza Copper prospect is located 115 kilometres northeast of Hazelton, on a small hill on the east side of Lion Creek, 6 kilometres south of Kaza Lake. There is some confusion between these showings and the Fred deposit (094D 032) to the north.

The property is underlain by the Lower Jurassic Telkwa Formation of the Hazelton Group, which consists of basalt and andesite flows, breccias and tuffs and an overlying sedimentary unit consisting of siltstones, sandstones and chert pebble conglomerates. Limestone lenses and pods occur between some of the flows. Steeply-dipping, north-trending felsic dikes of the Eocene Kastberg Intrusions are common in the area of the showings.

The main trenched area encompassing Trenches T-K-1 through T-K-6 is now referred to as the "Main Trend". This consists of a north-northwest - south-southeast trending zone of relatively continuous skarn-style sulphide zones, with narrow massive magnetite zones. These occur within Telkwa Formation feldspar porphyritic calc-alkaline andesite, spatially associated with quartz-feldspar porphyritic dykes, commonly strongly calcareous, extending conformably to local stratigraphy. One major dyke extends throughout the Main Trend area; towards the southern limit of the trenched area, the zone has a south-east orientation.

Mineralization consists of massive to semi-massive pyrite and chalcopyrite plus/minus bornite, developed most strongly along dyke margins. Bornite is more abundant towards the southern end of the Main Trend. Endoskarn sulphide mineralization also extends roughly one metre into the dikes; gold values tend to be highest within endoskarn and immediate exoskarn (hostrock) mineralization. Host rock sulphide mineralization is commonly associated with small shear zones, where sulphides have undergone near complete oxidation. Narrow magnetite skarn zones are most common within southern trenches, with variable, sub-economic to low copper and gold values.

Other descriptions indicate patchy exposures of an epidote-calcite skarn containing pyrite and chalcopyrite and minor pink garnet. Minor amounts of chalcopyrite and bornite are present in quartz-orthoclase-epidote veinlets and also disseminated in a limestone lens near the main showing. Sphalerite is also reported.

North of trench K-T-6, along strike extension of the Main Trend, gold-bearing chalcopyrite occurs as veinlets and blebs within limestone. Values to 2.62 per cent copper, 0.918 grams per tonne gold and 37.8 grams per tonne silver were returned from composite grab sampling from 2003 (Assessment Report 27354).

A second major zone, the east-southeast–west-northwest trending "Hornblendite Zone" was identified in 2003. Past exploration in the North Showing area identified numerous small hornblendite units, commonly with high pyrite and/or chalcopyrite contents. These, originally believed to be dykes, are now believed to be zones of calc-silicate skarn alteration of a distinct metasomatic geochemistry to that seen in the Main Skarn area, resulting in formation of abundant hornblende.

Pyrite and chalcopyrite occur within hornblende-rich skarn alteration zones yielded grab and composite grab samples to 3.08 per cent copper, 11.7 grams per tonne gold and 67 grams per tonne silver (Assessment Report 27354).

Several trends of pyrite-chalcopyrite skarn parallel to, and to the northeast of, the Main Trend are also known.

A chip sample across one of the best exposed parts of the main skarn showing assayed 0.88 per cent copper, 15.43 grams per tonne gold and 12.7 grams per tonne silver across 4.0 metres (Assessment Report 4477, page 7). Drillhole number 9 intersected 1.2 metres assaying 1.17 per cent copper, 14.4 grams per tonne gold and 120.0 grams per tonne silver (Energy, Mines and Resources CORPFILE – Kaza Copper Limited).

The earliest records on the Kaza project area date from 1967, when the Fire claim block was controlled by Mr. R.M. Tait. In 1968, Mr. Tait conducted further exploration, including geological mapping and a 10-hole, 660-metre diamond drilling program. The best assayed intersection was 1.17 per cent copper, 14.4 grams per tonne gold and 121.1 grams per tonne silver over 1.2 metres in hole No. 9 (Property File Cyprus Anvil Dean, P.M. 1973).

In 1973, Dynasty Explorations Limited conducted soil sampling and magnetometer surveys across the mineralized area. Dynasty also analyzed six rock samples taken from the best exposures of skarn in the main mineralized trench. The best of these returned 1.39 per cent copper, 2.4 grams per tonne gold and 11.7 grams per tonne silver across 1.8 metres (Property File Cyprus Anvil Dean, P.M., 1973).

In 1980, Dome Exploration (Canada) Ltd. conducted soil geochemical surveying and chip sampling. In June 1983, Asarco Exploration Company of Canada Ltd. staked the 20-unit Blue claim across the Main Trend, and obtained numerous samples for petrographic analysis. In August 1985, Mr. Robert M. Tait staked the Log 1-4 claims covering the Main Trend.

In 1996, Everest Mines and Minerals Ltd. obtained five 10-kilogram, minus-20 mesh stream sediment samples. Everest also mapped the known showings in detail, divided the main trend into the Main, South and North showings, and obtained 29 rock chip/channel samples.

The Main and South showings are located along the same topographic lineament covering a distance of 370 metres. The North showing was described as three gossanous, pod-like bodies up to 20 metres in diameter. Also in 1996, I.S. Thompson of the firm of Deny, Mitchener, Booth and Wahl collected four composite grab and one grab sample from the Kaza showings. In August 1996, Everest entered into an option agreement with Mr. R.M. Tait on the thirteen claims then comprising the Kaza property. In 1997, Everest conducted soil geochemical, ground magnetometer and induced polarization (IP) chargeability and resistivity surveys, as well as an intensive mechanical trenching program.

A base line oriented at 330 degrees was established, with eleven grid lines spaced 100 metres apart. A total of 381 soil samples were obtained at 25-metre sample intervals. The trenching program targeted the strongest geochemical anomalies along the main trend and exposed massive sulphide zone up to 23 metres wide with an inferred strike length of 450 metres.

In 2002, Northern Hemisphere Development Corp. entered into an option agreement to acquire both the Kaza and Northstar (Fred) (094D 032) properties. Claims held by Northern Hemisphere on the two properties are contiguous.

In 2003, Northern Hemisphere conducted line cutting to extend existing grids on both the Northstar and Kaza project areas. This was followed by soil geochemical sampling, geological mapping, rock and silt sampling covering the grid extensions of both project areas. Detailed geological mapping and rock sampling were also conducted over the 1997 grids at both project areas, and directly northwest of the previously gridded portion of the Northstar project area. Ground magnetometer and Induced Polarization surveys were conducted over the entire newly cut grids at the Kaza project area; Chargeability and resistivity I.P. surveying was also done across much of the grid extension of the Northstar project area. A two-line gravity survey was conducted across the central portion of the Northstar project area.

In 2004, Northern Hemisphere drilling on the Kaza area consisted of 1,133.2 metres in five NQ diamond-drill holes. Three holes tested the east-southeast trending Hornblendite Zone. One hole tested the down-dip extension of the Main Zone south of the Hornblendite Zone, and one hole tested the Main Trend south of Hole KZ-04-03.
