Name: Red Mountain mine.

Location: The Red Mountain gold property is situated about 18 km east-north-east of Stewart, in north-western British Columbia, Canada.

Controlling Company: On April 15, 2014, IDM Mining entered into an option agreement for the Red Mountain mine project with Seabridge through IDM’s predecessor company, Revolution Resources Corporation. Subsequent to the option agreement, Revolution Resources Corporation underwent restructuring and a name change to IDM Mining.

Brief History: Placer mining started in Bitter Creek at the base of Red Mountain at the turn of the century, but significant work on the current deposit began in 1988 when Wotan Resources staked claims and optioned the property to Bond Gold Canada in 1989. In that year, gold mineralisation in the Marc and Brad zones were discovered by drilling. Lac Minerals acquired Bond in 1991. Surface drilling on the Marc, AV and JW zones continued from 1991 to 1994. Underground exploration of the Marc zone was conducted in 1993 and 1994. In 1995, Lac was acquired by Barrick Gold, which subsequently optioned the property to Royal Oak Mines in 1996. North American Minerals Corp (NAMC) acquired the property from the receivership sale of Royal Oak in 2000. NAMC subsequently sold the property to Seabridge in 2002, which optioned the property to Banks Island Gold. Banks terminated the option in 2013 and the property reverted to Seabridge, which subsequently optioned the property to IDM in 2014.

Brief Description: The Red Mountain property consists of 47 contiguous mineral claims totalling 17 125 ha.

Geology/Mineralisation: Red Mountain is located near the western margin of the Stikine terrain, in the Intermontane belt. There are three primary stratigraphic elements in Stikinia – middle and upper triassic clastic rocks of the Stuhini Group, lower and middle Jurassic volcanic and clastic rocks of the Hazelton Group and upper Jurassic sedimen- tary rocks of the Bowser Lake Group. All are present in the Stewart area. Many primary textures are preserved in rocks from all of these groups and mineralogy suggests that the regional metamorphic grade is probably lower greenschist facies.

Mineralised zones consist of crudely tabular, north-westerly trending and moderately to steeply south-westerly dipping gold- and silver-bearing iron sulphide stockworks. Pyrite is the predominant sulphide; however, locally pyrrhotite is important. The stockworks zones are developed primarily within the Hillside porphyry and, to a lesser extent, in rafts of sedimentary and volcaniclastic rocks.

The stockwork zones consist of pyrite microveins, coarse-grained pyrite veins, irregular coarse-grained pyrite masses and breccia matrix pyrite hosted in a pale, strongly sericite altered porphyry. Vein widths vary from 0.1 cm to about 80 cm and widths of 1 cm to 3 cm are most common. The veins are variably spaced and average two to ten metres. The veins are very often heavily fractured or brecciated with infillings of fibrous quartz and calcite. Orientations of veins in the stockworks are variable; however, sets with north-westerly trends and moderate to steep north-easterly and south-westerly dips have been identified in underground workings.

The pyrite veins typically carry gold grades ranging from about 3 g/t to greater than 100 g/t. Gold occurs in grains of native gold, electrum, petzite and a variety of gold tellurides and sulphosalts. The stockwork zones are surrounded by a more widespread zone of disseminated pyrite and pyrrhotite alteration.

Resources: Total measured and indicated resources as at July 23, 2014, were 1.45-million tonnes, with an in situ gold grade of 8.15 g/t of gold and 29.57 g/t of silver. Inferred resources were 332 900 t, with an in situ grade of 7.69 g/t of gold and 12.72 g/t of silver.

Products: Gold and silver.

Mining Method: Longhole stoping will be used for mining blocks steeper than 55º, which represents about 82% of mineable tonnage. Drift and fill will be used for mining blocks with dips of less than 55º, which represents about 18% of the mineable tonnage. Cemented and uncemented rock fill will be used as backfill to maximise mining recovery.

Major Infrastructure and Equipment: The project envisions the upgrading or construction of about 25 km of seasonal access road from the Glacier highway to the project site and about 5 km of on-site service roads to access the mine portals, the tailings management facility and other working areas. Also to be built are crushing and grinding circuits and a gold extraction plant; a tailings management facility and impoundment; the temporary development waste storage areas; an administration office, a mine dry facility, a maintenance shop, a warehouse and an emergency camp; an electrical connection to BC Hydro; a transmission line adjacent to the seasonal access road and an on-site substation and distribution network; process and fire water storage and distribution; and a sewage septic system.

Prospects: IDM submitted a project description to the British Columbia Environment Assessment Office in November 2014, initia- ting an environmental assessment for the Red Mountain project.

Contact Person: President, CEO and director Rob McLeod.
