The Reko 10 occurrence is located east of Renfrew Creek, approximately 7.5 kilometres north east of Fairy Lake.

The area is mapped by Muller (Geological Survey of Canada Open File 821) as primarily diorite of the Mesozoic and/or Paleozoic Westcoast Complex. An east trending band of limestone is also mapped. Volcanics of the Lower Jurassic Bonanza Group lie to the north.

The north part of the Reko property is underlain by grey to white crystalline limestone, and the central and south part is underlain mainly by intrusive breccia. Several bodies of limestone also occur in the central and south part. The primary fragments of the breccia are fine grained and dark grayish green in colour, resembling andesite, and some contain amygdules. This andesitic rock was successively intruded by mafic-rich and mafic-poor diorite. The breccia grades to massive, mesocratic diorite to the south, and to massive andesite at about the 600 metre level on the west side of the east ridge. A set of long, narrow, fine-grained grey dykes strike 020 degrees and transects all other rocks. Most limestone bodies have been successively intruded by dykes of andesite and leucodiorite. It is thought that, prior to diorite intrusion, andesite underlay the limestone and also intruded it.

There are 3 zones included in the Reko 10 occurrence:

1.) Zone 1 (South Pit A) is exposed for 12 metres and a width of about 5 metres. Drilling has indicated that it is not much larger than the surface exposure. It consists of 35 per cent magnetite, 35 per cent garnet and 30 per cent pyrrhotite. Chalcopyrite occurs as small blebs, minute veinlets and fine disseminations. Rocks in the drill holes include limestone and andesite. An estimated 41,000 tonnes of ore occurs in Zone 1 (Geology and Exploration in B.C., 1974, page 170). No grade was given. In 2005, two diamond drill holes were completed on the zone. The first hole (Reko DDH 1) intersected 4.06 metres of massive magnetite mineralization between 10.77 to 14.83 metres depth enclosed by marble and diorite (Assessment Report 28059).

In 2005, a drill hole (Reko 10 DDH 1), located on the Zone 1 (South Pit A) occurrence intersected 4.06 metres of massive magnetite averaging 58.38 per cent total iron and 0.180 per cent copper (Owsiacki, G. (2008-03-11): Technical Report – Geological Summary Pearson Project).

2.) Zone 2 (South Pit B) is located about 200 metres southwest of Zone 1. A drill hole put down on the centre of the zone shows magnetite disseminated in epidote-pyroxene-garnet skarn from 2.4 to 25 metres. Pyrite and chalcopyrite occur locally. Rock types found include garnetite and andesite. An estimated 970,000 tonnes of ore were calculated for Zone 2 (Geology and Exploration in B.C, 1974, page 170. No grade was given. In 2004, the zone was tested by two drill holes.

3.) Zone 3 (South Pit C) is located about 425 metres northwest of Zone 2. The zone is not exposed and is known only from the drilling of a magnetic anomaly. A hole put down on the centre of the zone shows, from 19 to 24 metres, magnetite, pyrrhotite and pyrite, both disseminated and as veins or veinlets. Below 24 metres the rock is predominantly diorite. Zone 3 has an estimated 32,000 tonnes or ore (Geology and Exploration in B.C., 1974, page 170). No grade was given.

In 1975, Reako Explorations Ltd. reported an ore reserve estimate on the Reko property (see Reko 3 -- 092C 090, Reko 38 -- 092C 110 and Reko North -- 092C 146) of 4,500,000 tonnes grading 22 per cent iron (George Cross News Letter No.207, 1975). The same reference also reported a 4.6 metre section of drill core (location not reported) that graded 1.5 per cent copper and 6.86 grams per tonne gold.

Work History

In 1970, bulldozing and blasting by B.C. Forest Products road-building crews uncovered showings of magnetite and sulphides near the upper reaches of Renfrew Creek. The Reko 1-6 claims were staked on these showings in July 1970 by Mr. M. Levasseur. Sampling of the exposed mineralization was subsequently carried out. Levasseur and associates incorporated Reako Explorations Ltd. in July 1971 and completed a magnetometer survey and six short drill holes, totalling 37 metres. In 1972 and 1973, programs of geological mapping, 120 line-kilometres of ground magnetometer surveys, 19 line-kilometres of induced polarization surveys, trenching and 100 diamond drill holes, totalling 5300 metres, were completed on the Reko 3, 4, 9, 10 and 42 claims. In 1974, a further six diamond drill holes, totalling 89 metres, were completed on the Reko 37 claim.

In 2003 through 2010, Emerald Fields Resource and Pacific Iron Ore Corporation completed various exploration projects in the area as apart of the Pearson Project. These included prospecting, diamond drilling, ground and airborne geophysical surveys, geological mapping and geochemical sampling.
