The Tojo occurrence is located 2 kilometres north of Mayo Creek and 12.2 kilometres west of Kalum Lake. Eagle Plains Resources Ltd. discovered it in 2003 during prospecting along the northern side of a ridge that was recently exposed by a retreating ice.

Regionally, the area is underlain by Jurassic to Cretaceous Bowser Lake Group sediments which have been intruded by granodiorite and diorite of the Cretaceous to Tertiary Coast Plutonic Complex. The sediments consist of a northeast striking, southeast dipping sequence of banded siltstone, shale, argillite and minor conglomerate, sandstone and tuff.

The Tojo area contains sheeted quartz veins, with high gold and silver grades, hosted in strongly ankeritic granodiorite, 1.1 kilometres southwest of the Chris (MINFILE 103I 174) vein. Rubble and sub-crop of mineralized veins occur over an area of at least 20 metres by 80 metres. The veins are generally 1 to 20 centimetres thick and have densities of between 2 and 10 per linear metre. The veins show weak to moderate limonite after sulphide. Comb quartz is the most common vein texture. Another mineralized vein or zone, referred to as the Tracy zone, is reported to the southwest.

In 2003, three grab samples are reported to have yielded 73.1 grams per tonne gold and 495.4 grams per tonne silver, 6.8 grams per tonne gold and 65.8 grams per tonne silver, 4.0 grams per tonne gold and 850.1 grams per tonne silver, respectively (Daignault, P.M., Sharp, R.J. (2007-12-27): 2007 Exploration and Geological Report for the Kalum Property).

In 2005, a grab sample (JSK03R31) assayed 58.1 grams per tonne gold and 439.9 grams per tonne silver (Daignault, P.M., Sharp, R.J. (2007-12-27): 2007 Exploration and Geological Report for the Kalum Property).

Work History

In 2003, Eagle Plains Resources Ltd. had acquired the 500-unit Kalum property to cover the Allard stock, a 4 by 11 kilometre intrusion that has been mapped west of Kitsumkalum Lake. The Kalum property encompasses several historically documented occurrences referred to in their 2003 Assessment Report 27417: Kalum (103I 019), Burn (103I 211), Quartz Silver (103I 018), Allard (103I 151), Misty (103I 213), Chris (103I 174), Martin (103I 020) and Hat (103I 173). Several new discoveries were also described.

In 2004, Eagle Plains Resources Ltd. continued exploration for an intrusion-related gold deposit on its Kalum property. The program comprised a 1500-line kilometre airborne geophysical survey, on-the-ground evaluation of targets and the drilling of 19 holes, totalling 1958 metres. The geophysical survey recovered magnetic and time-domain electromagnetic data.

In 2005, Eagle Plains Resources completed a program of soil, silt and rock sampling and geological mapping on the area.

In 2007, Mountain Capital Inc. optioned the property and in 2008 undertook a program of soil and rock sampling, a 4.1 line-kilometre induced polarization survey and 11 diamond drill holes on the Burn (MINFILE 103I 211) occurrence area. The option was terminated in May of 2009.

In 2009, Windstorm Resources Inc. entered into a Letter of Intent with Eagle Plains to earn a 60 per cent interest in the property and completed a program of prospecting, geochemical sampling and an induced polarization survey on the area.

In 2010, a program of geological mapping and six diamond drill holes, totalling 419.11 metres, were completed on the Tuppie-Cirque (MINFILE 103I 228) occurrence.

In early 2012, Clemson Resources Corp. entered into an Option Agreement with Eagle Plains Resources to acquire a 60 per cent interest in the property.

In 2020, Rex Resources completed a 247 line-kilometre airborne magnetic and radiometric geophysical survey on the area as the Kalum property.
