The Rottenstone
Nickel-Copper-PGE Project

A significant high grade nickel-copper-PGE play

The Rottenstone property, which includes a past producer the Rottenstone Mine, is located approximately 145 kilometers north-northeast of the town of La Ronge, Saskatchewan. The property consists of 8-claims totaling 13,364 hectares and is a joint venture agreement between Mantis Mineral Corp and Uravan Minerals Inc.

Geologically the property is located in the southeastern portion of the Trans-Hudson origin within the Rottenstone domain. The Rottenstone domain is known to contain several bodies hosting nickel-copper-platinum group elements is ultramafic rocks. The Rottenstone Mine occurs in one of these bodies.

Between 1965 to 1968 approximately 40,000 tons of ore was mined from the Rottenstone deposit which reportedly contained a reserve of 50,000 to 60,000 tons grading 2% nickel, 2% copper, 0.22 ounce per ton platinum and 0.15 ounce per ton palladium.

The Rottenstone deposit is unique because of its high grade (2.0% Ni, 2.0% Cu, 0.22 opt Pt, 0.15 opt Pd),

and high sulphide content contained in a small magmatic body.

Theoretically, a larger, yet to be discovered system must have been responsible for supplying the metals that formed the Rottenstone deposit.

Mantis is planning to conduct a deep penetrating high resolution electromagnetic survey (VTEM) to test for the depth and extension feeder system of the Rottenstone deposit.
