Details and Description

Record Ridge is an intermediate-advanced stage magnesium exploration project located in southern B.C., Canada. It is located 7.5 kilometres west to southwest of the town of Rossland, B.C., Canada; five kilometres north of the U.S.-Canada border; and approximately 400 kilometres east of Vancouver, B.C.

Mineralization is related to the elevated magnesium content in serpentized mafic rocks.

WHY retains 100% of the mineral rights to the property, has agreements with the B.C. government for exploration access, and is in the process of evaluating options for procurement of surface rights for continued development.

  • 29 contiguous mineral claims totaling 8,972 hectares

Geology and Mineralization
Resource Relative to Ore Body

The Record Ridge area is located with the Quesnel Terrain of the Intermontane Belt. It is comprised of a highly deformed Jurassic (180 Ma) age volcanic island arc-back arc basin complex intruded by Tertiary volcanic and plutonic rocks. The exploration area is underlain primarily by the Record Ridge Ultramafic Body of Paleozoic age. This unit is bound on the north by the volcanics of the Tertiary Marron Formation, on the east and southeast by the volcanic rocks of the Jurassic Elise Formation and on the west and southwest by the Tertiary age Coryell intrusive suite. Regional metamorphism has reached greenschist facies in the Project area.

Mineralization containing economically significant concentrations of magnesium is known to occur in the ultramafic rocks which have undergone serpentinization. This rock type makes up the predominant lithology described at the Project, and occurs widespread. Lower concentrations of magnesium within the serpentinite are present in dioritic intrusive rocks and lenses of andesite/diagabbro.

Exploration Status

During the 2007, 2008 and 2011 field seasons, WHY conducted surface mapping, surface sampling and diamond drilling on the Project. The surface mapping was conducted at a 1:2,500 scale focused on the ultramafic rocks. Samples were collected from outcrop and analyzed by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) for 24 elements. A total of 30 samples were collected and analyzed. The results of this work delineated a high magnesium anomaly located in the east flank of the Record Ridge, presumed to lie above the serpentinite unit. The Project resource estimation is based on information from 77 diamond core drillholes totaling 10,310 m, with 5,836 assays. These were carefully logged, sampled and tested with 24-or 32-element ICP-AES analysis.

Economic Analysis of the MgO Plant
  • Project duration 20 years (based on economic analysis);
  • 100% owned;
  • PFS demonstrated production of high-purity >99% magnesia (MgO);
  • PFS based on MgO price of $1,500/t USD;
  • After-tax NPV $872 million USD at 5% discount;
  • Total installed capital cost of $27.86 million;
  • IRR 72%
  • Payback Period of 1.43 years

Record Ridge Commercial Proprietary Hydrometallurgical Process

The baseline Commercial plant strategy analyzed in Pre-Feasibility Study for Record Ridge Magnesia Production Plant is to produce a 98% spray roasted MgO powder product. With additional processing steps it would be possible to take this product and produce a caustic calcined magnesia (CCM) with a purity >99% with the potential for a higher selling price. As illustrated in Figure 18, it would require the addition of “MgO Washing” followed by “Calcination” in a multi-hearth furnace.
