The Nizi property is located 10 kilometres northeast of Beale Lake and 80 kilometres northeast of the community of Dease Lake.

The area was originally mapped as being underlain by sedimentary rocks of the Sylvester Group (Geological Survey of Canada Open File 610) but work by Gabrielse shows the area to be part of a Devonian and Mississippian tectonite assemblage (the Rapid River tectonite) probably with Kootenay terrane affinities (Geological Survey of Canada Open File 2779). A large body of hornblende diorite, part of the Upper Devonian(?) to Upper Triassic Sylvester Complex, is shown to intrude the tectonite in the area of the prospect.

The main mineralized area of the Nizi prospect is reported to occur within a wedge of volcanics that is flanked on either side by a metasedimentary sequence (Assessment Report 22840). The volcanics are intruded by gabbro/diorite bodies and a granodiorite to quartz monzonite intrusion. Two minor ultramafic stocks also intrude the metasediments. The key volcanic formation is comprised of mafic, intermediate and more felsic units. Most of the known gold mineralization is associated with shear/fault structures within the intermediate and felsic units. There is no evidence of major faulting although numerous minor shear/fault structures occur throughout the property.

All mineralization is associated with shears, faults and fractures on the property. Numerous zones are documented in an area of at least 2 kilometres in length by several hundred metres in width. Significant mineralization occurs in the following associations: 1) gold-bearing quartz (+/- carbonate) veins/breccia which carry significant silver and varying amounts of pyrite, sphalerite, galena and chalcopyrite and have associated accessory sericite and barite. A fine-grained black mineral, possibly tourmaline, is an important alteration mineral occurring as a pervasive and fracture-controlled mineral in the silicified rocks; 2) disseminated to semi massive bands of sphalerite, galena, and chalcopyrite with silver and gold, subdivided into (a) quartz-poor with nil to low gold values (b) quartz-bearing with low to moderate gold values; 3) silicified zones in the felsic volcanics.

Chip/channel samples (of type 1 association) assayed up to 27.09 grams per tonne gold and 1220.58 grams per tonne silver over 2 metres (Assessment Report 22840). These veins are continuous over several hundred metres but are fairly narrow (1 to 2 metres). The highest values have come from the Discovery vein and the Surprise vein.

Grab samples from the H zone (mineral association type 2a) assayed up to 2.33 grams per tonne gold and 627.43 grams per tonne silver, 18.3 per cent zinc and 7.5 per cent lead (Assessment Report 22840). In the Gully zones A and B (mineral association type 2b), samples assayed up to 12.0 grams per tonne gold and up to 3428 grams per tonne silver. These base metal zones are generally very narrow (less than 20 centimetres) and traceable for tens of metres.

A few zones of silicified volcanics (mineral association type 3) usually near quartz veins locally contain anomalous to low-grade gold values (less than 3.4 grams per tonne).

Drilling in 1992 indicated continuity of the gold-bearing structures at depth but the gold values themselves were lower than surface assays. One drillhole, testing the Sericite zone, averaged 5.73 grams per tonne gold over 13.77 metres (Assessment Report 22840, page 38). A channel sample across 2.3 metres assayed 94.01 grams per tonne gold and 841.72 grams per tonne silver (George Cross News Letter - June 26, 1992).

Work History

In 1970, John Foster completed a program of geological mapping and soil sampling on the Nizi claims. Assays of high-grade vein mineralization from two different locations on the property are reported to have yielded 0.6 and 2.2 grams per tonne gold, 1270 and 1100 grams per tonne silver, 0.24 and 3.92 per cent lead with 44.70 and 36.46 per cent zinc, respectively (Assessment Report 7818).

In 1972, Sumac Mines Ltd. conducted geological and geochemical (approximately 1000 soils and silts) surveys. In 1979, Cordilleran Engineering ran a similar program (592 soils, 63 rock and 93 silts). Three select grab samples (12913, 12935 and 12960) from quartz veins, 0.02 to 0.60 metre wide, with pyrite and arsenopyrite mineralization assayed from 3.0 to 11.3 grams per tonne gold with 33.4 to 298 grams per tonne silver, whereas a sample (12969) of vein material hosting sphalerite and galena assayed 0.9 gram per tonne gold, 468 grams per tonne silver, 10.50 per cent zinc and 2.63 per cent lead (Assessment Report 7818).

In 1982, Regional Resources conducted a minor soil and rock sampling program. A 0.20-metre chip sample (4581) across a quartz vein hosting massive sphalerite, pyrite and galena mineralization assayed 2.8 grams per tonne gold, 2140 grams per tonne silver, 13.00 per cent zinc and 7.70 per cent lead (Assessment Report 11154).

Izumi Exploration, in 1987, conducted a large program consisting of geophysical and geochemical (202 rocks and 1440 soils) surveys. In 1992, Gold Fields Canada Minerals drilled five diamond drill holes, collected 625 soil and 650 rock samples and conducted ground geophysical surveys.

In 1996, Madrona Mining Limited drilled six holes, totalling 914 metres. A 4.5-metre intercept graded 1.16 grams per tonne gold, 733.4 grams per tonne silver and 7.8 per cent zinc (Exploration in British Columbia 1996, page B13). Madrona Mining Limited drilled four holes in 1997 to further evaluate the stockwork mineralization in the Discovery vein area and a fifth hole to test a rhyolite flow-dome complex. To date, a zone measuring 100 by 225 metres, extending to a depth of 125 metres, has been identified as having bulk mining potential in the Discovery area. Gold and silver mineralization occurs in a subvertical to vertical, multi-stage, quartz vein-stockwork system and associated hydrothermal breccia, hosted by altered andesitic to rhyolitic flows, tuffs and subvolcanic intrusions, probably Paleogene and/or Neogene age.

In Fieldwork 1997, pages 17-1 to 17-13, the case that this polymetallic mineralization is epithermal in nature and Eocene is based, in part, on an interpretation of some lead isotope data. The host volcanics and rhyolite are also thought to be Eocene. In Fieldwork 2002, page 54, the Nizi veins and enclosing rocks are assigned to the Eocene Zinc Lake volcanic/intrusive sequence, which is correlated with the Major Hart pluton.

Recent work has focussed on the veins set in an area 2 by 1 kilometres elongate in a northwest direction. Two mineralization styles can be described. One set is a sulphide-poor gold, silver, quartz veins and stockworks associated with pervasive silicification; the other is sulphide-rich iron carbonate-sphalerite-galena veins associated with extensive carbonate alteration. Six mineralized zones are outlined: Zinc Lake, Discovery/Surprise vein, Grizzly Ridge, H, Gully A and Gully B. Currently, the Discovery/Surprise vein is the best target. As can be seen above, grades vary.

In 2007, Romios Gold Resources mapped and evaluated the known showings and defined potential drill targets for future work on the Nizi property. A program consisting of 1:5000-scale geological mapping, prospecting and rock sampling was conducted. In total, 43 rock samples were taken and 26 samples were subjected to ASD spectrometer petrographic analysis for clay and alteration mineralogy.

In 2009, Kaminak Gold completed a program of a grid soil sampling and limited rock sampling on the area.

In 2021, Free Path Metals Inc. completed a program of grid soil sampling and rock sampling on the Nizi property. An outcrop sample (21209) of gossanous quartz-carbonate vein with sulphides assayed 5.21 per cent zinc, 150 grams per tonne silver and 9.71 grams per tonne gold (Assessment Report 39822).
