Constantine Announces 2018 Exploration Plans for Palmer Project, Southeast Alaska – 10,000 Meter Drill Program –
May 11, 2018
Vancouver, BC – Constantine Metal Resources Ltd. (TSX Venture – CEM) (“Constantine” or the “Company”) is pleased to announce its 2018 exploration plans for the Palmer Copper-Zinc-Silver-Gold Joint Venture Project (”Palmer” or “Project”), in Southeast Alaska. Plans include:
- 10,000 meter diamond drill program using two rigs starting early June
- Updated mineral resource estimate and Preliminary Economic Assessment study
- Advance plans to initiate permitting underground exploration development
Constantine’s 51% share of the Joint Venture budget to year end is approximately US$4.5 million.
10,000 Meter Drill Program
The 2018 drill program will continue to have a dual focus of exploring for new deposits while also systematically defining and expanding the South Wall & RW Zone mineral resources. Discovery of the exciting new silver-gold-zinc rich AG Zone in 2017, which returned 9.2 meters grading 312 g/t (9.1 opt) silver and 0.9 g/t gold in discovery hole CMR17-89 and 11.3% zinc over 17.8 meters in hole CMR17-92 (see Company news releases dated July 27, 2017 and August 17, 2017), highlights the district potential of the camp. AG Zone is open to expansion along strike and at depth and will be an important part of the 2018 drill program.
Drilling will also test new geophysical targets identified by a regional 1,137 line km airborne electromagnetic survey completed over the Project last year. Multiple targets sharing similar geophysical characteristics to the known South Wall deposit have been defined, several of which coincide with areas of VMS style mineralization and hydrothermal alteration exposed at surface. The targets occur both on Joint Venture ground and 100% Constantine ground (Figure 1).
Mineral Resource Estimate and PEA
An updated mineral resource estimate has been initiated that will incorporate drilling and analytical data acquired since the resource was last updated early 2015. In addition to significant new South Wall drill results (e.g. 2.5% Copper and 7.4% Zinc over 45.4 meters in hole CMR17-82) the resource estimation will also include evaluation of the new AG Zone discovery. Results of metallurgical test work currently underway (see Company news release dated February 27, 2018) will also be incorporated in the estimation, including assessing the viability of barite as a marketable commodity, and potential optimization of copper and zinc recoveries.
Upon completion of the updated resource, a Preliminary Economic Assessment (“PEA”) study will be initiated. The PEA will gauge the potential economic viability of the mineral resources, and will be the first such study to be commissioned for the Project. The Company is currently in the process of selecting a consulting firm to lead the PEA and is targeting the fall of 2018 for completion.
Underground Exploration Planning and Permitting
The Palmer Project Joint Venture intends to advance the planning and permitting of an underground exploration program that would include development of an underground access ramp. Underground access would importantly:
- Provide a platform for drilling to expand the South Wall deposit at depth and along strike
- Allow for the upgrading of existing mineral resources to support economic studies
- Allow for collection of important metallurgical, environmental and geotechnical data
- Enable the transition to year-round underground exploration work to advance this important new resource
Supporting technical studies as well as some surface construction are planned for the 2018 season.
About the Palmer Project
Palmer is a high-grade volcanogenic massive sulphide-sulphate (VMS) project, with an Inferred Mineral Resource of 8.1 million tonnes grading 1.41% copper, 5.25% zinc, 0.32 g/t gold and 31.7 g/t silver*. The Project is being advanced as a joint venture between Constantine (51%) and Dowa Metals & Mining Co Ltd. (49%), with Constantine as operator. The Project is located in a very accessible part of coastal Southeast Alaska, with road access to the edge of the property and within 60 kilometers of the year-round deep sea port of Haines. Mineralization at Palmer occurs within the same belt of rocks that is host to the Greens Creek mine, one of the world’s richest VMS deposits. VMS deposits are known to occur in clusters and with at least 25 separate base metal and/or barite occurrences and prospects on the Project, there is abundant potential for discovery of multiple deposits at Palmer.
About the Company
Constantine is a mineral exploration company led by a proven technical team with a focus on premier North American mining environments. In addition to the Company’s flagship copper-zinc-silver-gold Palmer VMS Project, Constantine also controls a portfolio of high-quality, 100% owned, gold projects in the Timmins camp, Ontario. This includes the large, well located Golden Mile Property in Timmins and the Munro Croesus Gold Property that is renowned for its exceptionally high-grade past production. Management is committed to providing shareholder value through discovery, meaningful community engagement, environmental stewardship, and responsible mineral exploration and development activities that support local jobs and businesses.
