The RAVEN occurrences are located in the Cayoosh Range north of Downton Creek, about 15 kilometres south of Seton Lake and 19 kilometres southwest of Lillooet, B.C., between elevations of 1340 and 1670 metres.

The region is underlain by the Mississippian to Jurassic Bridge River Complex (Group), which are exposed along a broad, complex antiformal structure that plunges northwest. The group consists mainly of a thick sequence of bedded chert, chert argillite and argillite intercalated with altered basaltic flows (greenstone) and minor limestone. The greenstone is altered to listwanite (quartz-carbonate alteration) and flooded by pyrite. Most of the Bridge River Group exhibits pumpellyite-prehnite metamorphic grade.

The Raven showing was first discovered by G. Polischuk in 1990 after gold-bearing pyrite float was discovered on a logging road at the south end of the claim and above Downton Creek. Subsequent soil geochemical sampling upslope led to the discovery of visible free gold in quartz-pyrite float and in trenches.

Limited outcrop at the Raven showing consists of listwanite altered greenstone containing extensive quartz veining varying from a few centimetres to 2 to 3 metres in thickness. The veins pinch and swell extensively and their attitudes are mostly irregular. However, a principal set strikes approximately north and dips vertically. These are interspersed with flat lying quartz veins dipping generally northeast. Mineralization consists of pyrite and arsenopyrite with chalcopyrite, galena, sphalerite and native gold. The gold-bearing veins are intimately associated with listwanite altered greenstone, dipping 40 degrees to the west. The best gold values occur in the hangingwall or footwall of greenstone layers and are accompanied by high arsenic, iron, bismuth and antimony with elevated copper values.

Locally, at least eleven areas of mineralization have been identified over an area of 650 by 150 metres. These have been referred to as the A, B, C, D, E, Discovery, Eagle, GP, Riley, Landing and Smokey zones. All the known occurrences, except the Discovery zone, occur along the western edge of northerly trending magnetic high anomalies (Assessment Report 32250). Pallas and South Pallas occurrences are north-northwesterly extensions of the "Raven Trend", associated with a variably listwanite-altered band of greenstone, while the South Downton showing is to the south-southeast.

Zone A consists of a 2 to 3 metre wide shear zone, striking 120 to 140 degrees and dipping vertically, hosted by sheared cherty argillites of the Bridge River Group at an elevation of 1340 metres. The mineralized zone is composed of sheared, pyritized and carbonate altered cherty argillite with irregular quartz vein varying from 5 to 15 centimetres in width. Dusty arsenopyrite and minor chalcopyrite occur along the fracture surfaces. In 1990, trenching and sampling yielded values of 27.95 grams per tonne gold across a true width of 2.0 metres, within a 3.5 metre wide shear zone which assayed 17.01 grams per tonne gold across its entire width (Assessment Report 21667).

Zone B is poorly exposed in an area of listwanite outcrops and rock bluffs at an elevation of 1533 metres. A lone trench (R-Tr90-2) has exposed an area of carbonate alteration and two quartz veins folded into an anti-formal structure which plunges at a shallow angle. The upper quartz vein is 0.2 metres wide and 1 metre above the main vein which varies from 2 to 2.5 metres in width and consists of quartz with varying amounts of arsenopyrite and pyrite. In 1990, a sample (16652) consisting of powdery arsenopyrite in a quartz vein in altered greenstone yielded 682.5 grams per tonne gold; while another sample (16658) from the same area assayed 12.5 grams per tonne gold (Assessment Report 21667). These were collected from outcrops to the north west of the trench.

Zone C consists of at least 3 mineralized shears at an elevation of 1562 metres. The two most western shears, exposed in trench R-Tr90-4, are 1 to 1.5 metres wide with a strike of 160 degrees and dipping 45 to 50 degrees west. The shears are hosted by cherty argillite with pyrite and lesser arsenopyrite and chalcopyrite and quartz veining. In 1990, two samples from trench R-Tr90-4 assayed 3.9 and 6.9 grams per tonne over 1 metre widths; while samples from trench R-Tr90-5 yielded values of 8.8 grams per tonne gold across a true width of 2.0 metres and up to 15.6 grams per tonne gold over 0.5 metre (Assessment Report 21667). In 2008, a grab sample yielded 16.75 grams per tonne gold, while a chip sample assayed 9.36 grams per tonne over 1 metre (Assessment Report 30497).

The D zone, as exposed by trench RTR91-9 at an elevation of 1595 metres, hosts quartz veins dipping 50 degrees to the west with visible gold over significant widths. The vein has been offset by right-lateral motion approximately 100 metres. Below and across the fault two veins were discovered on the hangingwall and footwall sides of listwanite altered greenstone.

In 1991, chip sampling by Reese River Resource Corporation over the entire 3.5 metre width of the D zone structure assayed 28.8 grams per tonne gold (Assessment Report 21668).

The same year diamond drilling of the zone yielded intercepts of:

(Assessment Report 21668)

In 1992, trench 92-T-12, below the D zone, exposed two veins in the hangingwall and footwall of listwanite-altered greenstone. Samples of the veins assayed 55.2 grams per tonne over 0.7 metre and 57.7 grams per tonne over 0.5 metre (Assessment Report 22874). In 2008, samples from the zone yielded 12.13 grams per tonne gold over 0.3 metre and 7.35 grams per tonne over 1.2 metres (Assessment Report 30497).

The E zone was discovered in 1992 when trenching uncovered a shallow dipping shear zone with quartz veins on the north side of the road between the A and B zones at an elevation of 1400 metres. The best sample (1-00376) assayed yielded 16.30 grams per tonne gold over 1 metre width from Trench 92-T-4 (Assessment Report 22874).

The Discovery zone, located between the E and B zones at an elevation of 1460 metres, is exposed over an area of 20 by 35 metres and consists of a mineralized listwanite-argillite contact. In 2008, grab samples assayed up to 44.41 grams per tonne gold (Assessment Report 30497). In 2015, a rough chip sample across an intensely oxidized shear zone collected on a northwest extension of the Discovery zone assayed 100.62 grams per tonne gold and 15.6 grams per tonne silver over 0.5 metres.

The Eagle zone, located southeast of the A zone at an elevation of 1310 metres, consists of a quartz-pyrite altered greenstone hosts chalcocite and bornite. In 2012, a grab sample assayed 19 per cent copper and 26 grams per tonne silver; while a 5 metre chip sample assayed 0.13 gram per tonne gold (Assessment Report 33410).

The GP zone is an area of black oxidized, white vuggy quartz float located uphill of D zone. The Riley and Landing zones cover favourable listwanite alteration with associated quartz and pyrite.

The Smokey zone, located approximately 300 metres east of the D zone and at an elevation of 1428 metres in a steep gully (Corona Creek), consists of highly pyritic greenstones with minor argillite and quartz. The host rocks have been silicified with carbonate and listwanite alteration. In 2008, sampling of the zone yielded copper values to 0.145 per cent with associated high iron and manganese values and elevated vanadium, nickel, arsenic and zinc values but no significant gold values (Assessment Report 30497).

To the north and up slope of the previous zones a sample mineralized float was located and referred to as the GP zone. In 2010, a float sample of oxidized quartz assayed 1.3 grams per tonne gold (Assessment Report 32250).

During 1990 through 1993, Reese River Resources completed programs of prospecting, trenching, rock and soil sampling, geological mapping and 12 diamond drill holes totaling 480.7 metres. During 2008 through 2017, Cresval Capital Corp. completed programs of rock, silt and soil sampling, geological mapping, an ortho-photo interpretation and ground magnetic and electromagnetic surveys on the area as the New Raven property.

In 2022, Red Eye Resources Ltd. conducted a small soil and rock sampling program in the vicinity of the South Downton occurrence, south-southeast of the Raven prospect. In 2023 Dinero Ventures Ltd. conducted a trenching and rock sampling program over some of the showings. Sample R-23-7, a select grab of grey quartz and dark brown weathered rock with trace visible gold from the A zone, assayed 69 grams per tonne gold and 11.15 grams per tonne silver (Assessment Report 41545).
