TORONTO, ONTARIO -- (Marketwire) -- 01/22/13 -- Rockcliff Resources Inc. (TSX VENTURE: RCR) is pleased to announce that a National Instrument 43-101 ("NI 43-101") Technical Report has been completed for its T-1 Copper Deposit, Tower Property, located in central Manitoba. The report entitled "Independent Technical Report, Tower Property, Grand Rapids, Manitoba" dated January 20, 2013 (the "Tower Deposit Report") was prepared by Zsuzsanna Magyarosi, Julie Selway, Jason Baker and Julie Palich, independent qualified persons under NI 43-101, for Caracle Creek International Consulting Inc. (Caracle Creek). The Tower Deposit Report is available for viewing on www.sedar.com
The Mineral Resource Statement prepared by Caracle Creek for the T-1 Copper Deposit is detailed below.
Table 1: Mineral Resource Statement, T-1 Copper Deposit, Manitoba Caracle Creek, December 2, 2012--------------------------------------------------------------------------------------------------------------------------------------------------------Resource ContainedCategory Tonnes Cu (%) Zn (%) Ag (g/t) Au (g/t) Pounds-Cu----------------------------------------------------------------------------Indicated 1,084,186 3.73 1.05 17.28 0.55 88,968,303Inferred 1,253,522 2.00 1.02 9.78 0.27 55,154,968----------------------------------------------------------------------------Notes: 1. CIM definitions were followed for the estimation of mineral resources. 2. Mineral resources are estimated at a Cu cut-off of 0.5%. 3. Cut-off grade was based on a copper price of US$3.63 per pound. 4. Given the tonnage, grade and orientation of the deposit, Caracle Creek considers the T-1 Copper Deposit to be reasonably amenable to extraction using underground mining methods. 5. Specific Gravity measurements were taken on a portion of the samples and where actual measurements were not available an average of 3.00 was used. 6. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
The Indicated and Inferred Mineral Resource for the T-1 Copper Deposit was classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves (December 2005) by Mr. Jason Baker P.Eng. (APENS#9627), who is an appropriate independent person for the purpose of NI 43-101. Mr. Baker has reviewed and approved the technical content of this news release.
The T-1 Copper Deposit is a remobilized, single, vertical dipping, high grade, VMS lens that is located immediately below a 100m thick layer of Paleozoic limestone cover. It consists of stringers and massive sulphide lenses of chalcopyrite, pyrite, pyrrhotite and sphalerite. Drilling has intersected the deposit over a strike length of 800m and to a vertical depth of up to 600m. The Deposit mineralization remains open along strike and at depth where surface (DPEM) and bore hole geophysics have indicated a continuation of the sulphide conductivity beyond the limits of the resource. The deposit is associated with a 12km long arcuate trending copper horizon hosting a second zone of copper mineralization (T-2 Copper Zone) and several additional conductive targets worthy of follow up exploration.
