Lynn Lake Project Overview
Location and Ownership
The Lynn Lake sulphide nickel deposit, located in northern Manitoba, was mined by Sherritt-Gordon from 1953 to 1976. The mine produced over 20 million tonnes of Ni-Cu, making it the 3rd largest nickel producer in North America. Eleven discrete zones were brought into production. When the mine was closed in 1976, it was during a period of stagnant growth in the nickel market. The mine was not closed because the ore was mined out. Prophecy’s project includes the majority of the claims that were operated by Sherritt-Gordon and the company is uniquely positioned to employ new exploration technologies in an underexplored nickel mine setting.
The site is readily accessible from the town of Lynn Lake, approximately 320 kilometres from Thompson, Manitoba along Provincial Highway 391. There is an airport at Lynn Lake which is serviced by Calm Air and Perimeter Air. Perimeter Air maintains a regular flight schedule into Lynn Lake from Winnipeg with stops in regional communities. A railway line is located at Lynn Lake, which extends south to Flin Flon, Manitoba and from there to the rest of Canada. The Lynn Lake project has both electrical power and rail available and can be operated year-round.
On January 12, 2010, Prophecy acquired the Lynn gabbros claims- which include five gabbro plugs - from VMS Ventures. Prophecy now has six of the seven known gabbro plugs in the Lynn Lake area and is the dominant player in terms of land size and resource base in the Lynn Lake nickel camp. In addition to a near-term production path using a disruptive Bioleach technology, the recent 2008 near-surface Disco Zone discovery, located 1.5km away from the outlined deposit, offers exciting exploration potential.
Geology and Mineralogy
The Lynn Lake A Plug property occurs in the deformed Precambrian metavolcanic and metasedimentary rocks, which belong to the Wasekwan Group. This is overlain by a metasedimentary succession, which is known as the Sickle Group. Nickel-copper- cobalt mineralization occurs only within the basic igneous plutons in the Lynn Lake Greenstone Belt, which extends westward from Southern Indian Lake in the east, to Laurie Lake on the Manitoba-Saskatchewan border. The A Plug nickel and copper deposits occur in one of these intrusions.
The A Plug is a complex intrusion where mineralization typically occurs within structurally controlled vertical pipes of remobilized peridotite and amphibolite that is largely discordant. The mineralization is magmatic in origin and was initially segregated and concentrated in a magma chamber prior to the vertical injections into pipes or lenticular shoots. The mineralized pipes are generally associated with extensive faulting and fracturing. Faulting ranges from imperceptible to a right-hand off-set of 60 to 100 m, where the west side is thrusted upward to the north.
The Lynn Lake deposit was discovered in 1941 by Austin McVeigh, who noticed oxidation of mafic rocks while prospecting for gold in northern Manitoba. McVeigh further established the presence of three anomalies in the area over the following years. Encouraged by these results, Sherritt-Gordon commenced a drilling program over what was to become known as the Lynn Lake Gabbros, in 1945. A third hole of this program intersected 84 feet (25.6m) of nickel mineralization and marked the beginning of the Lynn Lake nickel deposit.
Buoyed by the discovery, Sherritt-Gordon decided to move its entire operation from Sherridon, located over 250 km to the south, to the new site. The company freighted over 18,000 tons of material, including 50 houses, that would comprise the core of the town of Lynn Lake, thus establishing its sobriquet as "the town that moved."
The Lynn Lake nickel mine focused its production efforts on three main operations known as the 'A' mine, the 'Farley' mine, and the 'EL' mine. These deposits occur within two adjacent mafic-ultramafic intrusive plugs situated in the Lynn Lake greenstone belt. The deposit occurs in structurally controlled pipes of ultramafic and mafic cumulate rocks.
The 'A' mine was mined from 1953 to 1969, while the high-grade EL deposit came into production in 1954, and was mined until 1963. The Farley mine operated from 1961 until 1976, when nickel operations ceased in Lynn Lake.
Throughout their tenure, Sherritt Gordon delineated 11 discrete zones in the mine environment, not all of which were extracted.

Cautionary Note Regarding Mineral Resources and Mineral Reserves
Readers should refer to the Company's current technical reports and other continuous disclosure documents filed by the Company available on Sedar at www.sedar.com for further information on the mineral resource estimates of the Company's projects, which are subject to the qualifications and notes set forth therein, as well as for additional information relating to the Company more generally. Mineral resources which are not mineral reserves, do not have demonstrated economic viability. Inferred mineral resources have insufficient confidence to allow the meaningful application of technical and economic parameters or to enable an evaluation of economic viability suitable for public disclosure. Neither the Company nor readers can assume that all or any part of an inferred mineral resource will be upgraded to indicated or measured mineral resource. Most projects at the inferred mineral resource stage do not ever achieve successful commercial production. Each stage of a project is contingent on the positive results of the previous stage and that there is a significant risk that the results may not support or justify moving to the next stage.
Quality Control and Quality Assurance
Prophecy Platinum executes a quality control program to ensure best practice in sampling and analysis. Samples are cut and split for assay with the remaining sample retained for reference. Blanks, Standard Reference Material (SRM), and duplicates were inserted into the sample stream every 20th sample. A duplicate sample is taken every 20th sample of core. The selected sample is sawn in half and then sawn in half again. The quartered core is then placed into two different sample bags with different sample numbers and sealed. The SRM material comes from Natural Resources Canada and Analytical Solutions Limited. These were inserted into the sample stream immediately after the second duplicate. The SRMs used are WMS-1a, WPR-1 and WGB-1. Sample Blanks are obtained from two sources; granodiorite from a local quarry and garden marble from hardware stores in Whitehorse, Yukon. A Blank sample is inserted into the sample stream after the SRM. Assayed samples are transported in sealed and secured bags for preparation at ALS Chemex Prep Lab located in Whitehorse, Yukon. Pulverized (pulp) samples are shipped for analysis to ALS Chemex Assay Laboratory in Vancouver, B.C. ALS Chemex is an ISO/IEC 17025:2005 accredited laboratory and registered under ISO 9001:2000.
Quality assurance and quality control are monitored using scatterplots, Thompson-Howarth plots and statistical analysis to ensure duplicates, blanks and standard data are reliable and indicate robustness of overall results. ALS Chemex quality-assurance procedures are also included in this process."
