Overview
PMR has been working for several years to acquire key land parcels that comprise the Water Hen Project. The land position now consists fo approximately 1,440 acres of private and State of Minnesota mineral lands. PMR will focus its exploration efforts to identify the source of high grade Cu-Ni-PGE enriched orthopyroxenite dikes near the footwall of the Duluth Complex.
Project Location, Infrastructure and Land Tenure
The Project is located about 20 kilometers southeast of the Town of Hoyt Lakes, Minnesota, in proximity of Minnesota's Iron Range. The property is easily accessed by paved all weather roads and close to rail and electrical power.
Geology
Project Geology
The property is underlain by rocks fo the Duluth Complex which are part of the Midcontinent Rift System in Minnesota. The Duluth Complex has been explored for more than 50 years and this effort has lead to discovery of Cu-Ni-PGE rich massive sulfide desposits along the basal contact of the Duluth Complex (Fig. 4), including at the base of the Water Hen Oxide Ultramafic Intrusive (OUI) where the sulfide mineralization consists of numberous zones of disseminated to massive and semi-massive (net-textured) magmatic sulfides which extend out of the OUI into the surrounding troctolitic host rocks.
Exploration on the property has identified a non 43-101 compliant sulfide-rich copper-Nickel resource of 109.49 million tons grading 0.26% CU, adn 0.12% Ni. this resource is contained in a massive sulfide zone that has been identified at the base of the OUI and lies on land under lease by Prime Meridian Resources.
Historic drilling in the basal contact of the Duluth Complex at Water Hen has also intersected sulfide bearing orthopyroxenite dikes that grade up to 4.44% CU, 0.69% Ni, up to 1100 ppb Pt and 1750 ppb Pd., in the FN Formation, a contact zone between the Duluth Complex and the Virginia Formation. PMR believes that these dikes indicate the presence of a copper-nickel and PGE sulfide enriched footwall in the Duluth Complex similar to the high grade ores in the footwall of the Sudbury Igneous complex. These dikes are an indication of the potential for discovery of deposits with significantly higher grades than the existing known resource.
In addition to the high grade dikes, Compilation of the historic exploration completed in this area has identified an unexplained gravity anolmaly spatially associated with the dikes. This gravity anomaly lies on the contact between the Virginia Formation and the Duluth Complex. Airborne magnetic surveys performed by previous explorers has also defined an apparant embayment immediately west of the gravity anomaly. PMR suspects that this data may indicate a buried intrusion, possibly an orthopyroxenite which may be the source of the high grade dikes in the area.
History
Prime Meridian's Exploration Program
PMR now has most of the key land parcels to effectively explore the Water Hen Project area, focusing its exploration efforts to identify the source of the Cu-Ni-PGE enriched orthopyroxenite dikes near the footwall of the the Duluth Complex at Water Hen. PMR plans to undertake a program consisting of geological mapping and airborne and ground geophysical surveys prior to initiating drilling.
