IDM Mining Ltd. is pleased to announce an update to engineering and permitting activities and ongoing plans for the 2016 field season at the Red Mountain Gold Project, located in the Golden Triangle, east of Stewart B.C.
Knight Piesold Ltd, a geotechnical engineering company, has been retained to conduct a Geotechnical Site Investigation at the Bromley Humps area, located within the Bitter Creek Valley, approximately five kilometers west of the Red Mountain Gold Deposit. The purpose of this study is to support feasibility-level designs for the potential mineral processing plant site foundations and waste and water management facilities.
"IDM is committed to a high level of design and engineering for the proposed site infrastructure at Red Mountain," said Michael McPhie, Executive Chairman. "Our initial studies suggest that the Bromley Humps location represents an ideal location for the modest infrastructure required for a high-grade underground mine."
A total of 10 geotechnical holes are planned: nine vertical and one inclined within the proposed embankment areas for the tailings management facility ("TMF"), with drilling currently underway. These HQ-diameter holes will penetrate at least 30 meters into bedrock, and hydrological and geotechnical tests will be completed. Additionally, three water quality monitoring wells will be established at the Bromley Humps location. Test pits will be excavated to test potential construction and fill material sources from within and proximal to the proposed location for the facilities, primarily from glacial moraine and river gravels. It is anticipated that the drilling will be complete by early September 2016.
Geological mapping suggests that the Bromley Humps area is underlain primarily by bedrock with local thin overburden. The majority of the area is underlain by a competent, carbonate-rich gabbro intrusive, with local areas of cherty sedimentary rocks and diorite. Vegetation is primarily alder thickets and stands of cottonwood trees.
Additionally, working with lead engineering firm JDS Mining and Energy, the Company is completing engineering studies to advance the Red Mountain underground gold project, including underground metallurgical and geotechnical drilling, hydrological and groundwater studies, as well as road and powerline right-of-way studies. On July 12, 2016, IDM announced an Updated Preliminary Economic Assessment for the Project; the accompanying technical report will filed shortly on the Company website and at www.sedar.com.
IDM, through various contractors and consultants, has been actively completing environmental baseline and assessment work since 2014, including hydrological and ground water studies, wildlife, fisheries and geohazard surveys amongst others. Proactive, respectful, and transparent consultation and engagement with the Nisga'a Nation is ongoing.
