IDM Mining Announces Resource Update at Red Mountain and Reports Significant Increase in Measured and Indicated Resources and Boosts Gold Grade
January 23rd, 2016, Vancouver, BC – IDM Mining Ltd. (TSX-V:IDM) (“IDM” or the “Company”) is pleased to announce the results of an updated resource estimate for the Red Mountain Gold Project (“Red Mountain” or the “Project”), located in northwestern British Columbia near the town of Stewart, BC. The updated resource includes the results from additional drilling completed by IDM during 2016 which expanded mineralization along strike to the north, south, and down-dip, as well as additionally upgrading previous inferred resources. This estimate has yielded a 32% increase in contained Measured & Indicated (“M&I”) gold ounces, and an increase in average grade from 8.36 g/t to 8.75 g/t Au. The resource estimate is authored by Dr. Gilles Arseneau, P.Geo and Andrew Hamilton, P.Geo with input from IDM’s technical team.
The 2017 updated resource estimate at a 3.0 g/t Au cut-off represents an increase from the 2016 estimate by 142,200 oz Au and 275,900 oz Ag in the M&I categories. Resources in the Inferred category decreased by 42,700 oz Au and 48,200 oz Ag.
Rob McLeod, President and CEO, stated “Our 2016 drilling program was successful in expanding mineralization in all of the major mineralized zones, as well as demonstrating excellent continuity of wide zones of high-grade gold mineralization. Future underground drilling from the production-sized decline will continue to step-out in all directions, including targeting the northern extension of the mineralized trend, which can be traced a further 800 meters to the north of the current resources.”
“This updated resource model will now be handed over to our Feasibility Study team to be incorporated into a revised and expanded mine design,” said Michael McPhie, Executive Chairman of IDM Mining. “What is important to recognize about this revised and expanded resource update is it was made possible through a modest resource expansion drilling program during 2016.”
The updated mineral resources for the Red Mountain Project are reported at a 3.0 g/t Au cut-off effective January 23, 2017.
|Classification||Tonnage||Au (g/t)||Ag (g/t)||Oz Au||Oz Ag|
|Measured + Indicated||2,074,700||8.75||25||583,700||1,655,700|
The resource update incorporates information from previous drilling, as well as infill and step-out holes completed during 2016. Mineralization was primarily modelled using an approximate minimum 2.5 g/t gold grade, with consideration for sulphide type and abundance. An extensive quality control and quality assurance (“QA/QC”) review was completed on all 2016 and previous exploration work and a comparative analysis was performed on drill hole data, underground bulk sampling and geology.
The current mineral resource estimate, effective date January 23, 2017, was prepared by Dr. Gilles Arseneau, P.Geo, and Andrew Hamilton, P.Geo, using 3D GEMS block modeling software. Resources were estimated from 538 surface and underground drill holes in 4 x 4 x 4 meter blocks by ordinary kriging and anisotropic search ellipsoids designed to fit the geology. Grade estimates were based on capped 1.5 meter composited assay data. Gold values were top cut to 55 g/t and silver was top cut to 220 g/t.
Mineral Resource Statement for the Red Mountain Gold Project at a 3.0 g/t Au Cut-off Grade*
|Zone||Class||Tonnage||Au||Ag||Ounces Au||Ounces Ag|
|M & I Total||2,074,700||8.75||24.82||583,700||1,655,700|
*Note: 3.0 g/t Au is used as the cut-off grade for underground long hole stoping. Totals may not add due to rounding.
During 2016, underground drilling was completed on all major zones to gather metallurgical, geotechnical and hydrological data for inclusion within IDM’s ongoing feasibility study, as well as targeting areas of inferred or indicated resource classification with the objective of upgrading class. Additionally, step-out holes at 25 meter spacing, the minimum criteria for indicated resource classification were completed at all major zones. This was successful in expanding the known resources.
The Red Mountain Gold Project
The 17,125 hectare Red Mountain Gold Project is located in northwestern BC, 15km northeast of the town of Stewart. Discovered in 1989, the property was explored extensively until 1996 by Lac Minerals Ltd. and Royal Oak Mines Inc., with 466 diamond drill holes and over 2,000 meters of underground development completed, along with extensive engineering and environmental baseline work. Additional studies were completed over the past 12 years by Seabridge Gold Inc., North American Metals Corp. and Banks Island Gold Ltd.
Red Mountain is a porphyry-related hydrothermal gold system, located in the Stikine terrain. Gold mineralization is associated with, and partially hosted within an early to mid-Jurassic multi-phase intrusive complex, with associated volcanic and volcaniclastic rocks and sediments. Many gold mineralized zones occur on the Property, including five mineralized zones with established resource estimates. The mineralized zones have been folded, and are often separated by dip-slip fault zones. They vary in orientation from shallow to steeply dipping and are generally tabular. The Marc, AV and JW zones vary in widths from one to forty meters, averaging about sixteen meters in thickness. Gold and silver mineralization is associated with stockworks, disseminations and patches of coarse grained pyrite, surrounded by a pyrrhotite/sphalerite halo. Alteration facies includes strong quartz-sericite alteration.
