Toronto, Ontario. Rockcliff Copper Corporation (“Rockcliff“ or the “Company”) (TSX.V: RCU) is pleased to announce the completion of a National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) technical report titled “Technical Report on the Talbot Property, Manitoba, Canada”(the “Technical Report”) in respect of an initial Mineral Resource Estimate prepared by Roscoe Postle Associates Inc. (“RPA”) for the Talbot Deposit located on the Talbot Property, central Manitoba.
The Inferred Mineral Resource Statement prepared by RPA for the Talbot Deposit is detailed below.
Mineral Resource Statement, Talbot Deposit, Manitoba, RPA, January 26, 2016
1. CIM definitions were followed for the estimation of Mineral Resources.
2. Mineral resources are estimated at a cut-off grade of $140 Net Smelter Return (NSR) (equivalent to a copper NSR cut-off of 2.0%) using metal prices, estimated recoveries and offsite payments.
3. Mineral Resources are estimated using a long-term copper price of US$3.50 per pound, gold price of US$1450 per ounce, zinc price of US$1.25 per pound and silver price of US$22 per ounce.
4. An US$/C$ exchange rate of 1.18 was used.
5. A minimum mining width of 2 m was used.
6. The average bulk density is 3.2t per cubic meter.
7. Numbers may not add due to rounding.
8. Given the tonnage, grade and orientation of the deposit, RPA considers the Talbot Deposit to be reasonably amenable to extraction using underground mining methods.
9. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
Ken Lapierre, President and CEO commented, “The initial Mineral Resource Estimate on the Talbot Deposit is encouraging and the work completed to date on the property demonstrates the potential to host several high grade VMS deposits rich in copper, gold, zinc and silver. The deposit remains open to the north and at depth, has high copper, gold, zinc and silver grades, is hosted in multiple lenses and has the potential for expansion with additional drilling. Additional work in 2016 will attempt to upgrade and expand the present deposit resource, to determine the significance of the newly discovered North Copper Zone located 2.5km north of the deposit and to define the potential of the Central Target located 2.0km southeast of the deposit.”
Resource Estimation Methodology
An initial Mineral Resource estimate was carried out by RPA using a block model constructed in Datamine Studio 3, constrained by wireframes generated in Leapfrog Geo version 3. Densities were assigned using stoichiometry. Assay values were capped and composited to the full intercept length. Block grades were interpolated using a three pass search strategy and Inverse Distance raised to the fourth power (ID4). Block estimates were validated using visual inspection; comparison between composite sample and block means, and swath plots.
The Inferred Resource Estimate for the Talbot Deposit is classified as an "Inferred" Mineral Resource, and was classified in accordance with guidelines established by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) "Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines" dated November 23rd, 2003 and CIM "Definition Standards for Mineral Resources and Mineral Reserves" dated May 10, 2014. The drill hole database to support the Talbot Mineral Resource estimate is comprised of 45 drill holes drilled between 2003 and 2015 for a total of 27,044 m of drilling. Based on the current data available supporting the Mineral Resource Estimate, all material above the Mineral Resource cut-off grade was classified as Inferred.
Mineral Resources are estimated using a long-term gold price of US$1,450 per ounce, silver price of US$22 per ounce, copper price of US$3.50 per pound, and zinc price of US$1.25 per pound. An NSR cut-off value of C$140 was used for reporting of Mineral Resources. A minimum thickness criteria of two metres was applied for reporting purposes.
Extent to Which the Mineral Resource Estimate may be Materially Affected by any Known Relevant Issues
Neither Rockcliff’s Qualified Person, Ken Lapierre, nor RPA’s Qualified Person, Sean Horan, nor Management of Rockcliff is aware of any known environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant issues that may materially affect the estimate of the Mineral Resource.
The Technical Report, compiled in accordance with NI 43-101, will be filed on Rockcliff’s issuer profile on SEDAR within 45 days of release of this press release.
Talbot Mineralization and Exploration Potential
The Talbot Property hosts several target areas defined as “high priority” and worthy of follow-up exploration. The high grade Talbot Deposit is defined as a stratabound, volcanogenic massive sulphide deposit consisting of several lenses of coarse grain to stringer to massive sulphides of pyrite, chalcopyrite, sphalerite and pyrrhotite in a quartzofeldspathic gneiss. The deposit remains open at depth and to the north where bore hole geophysical surveys have indicated a continuation of the sulphide conductivity beyond the present limits of the resource. The newly discovered North Copper Zone located 2.5km north of the Talbot Deposit is associated with a large ZTEM anomaly and bore hole
geophysics suggest the present drill holes only intersected the top edge of a strong, large untested conductor. The Central Target is a large untested VTEM/ZTEM anomaly located 2.0km southeast of the Talbot Deposit with geophysical signatures similar to the Talbot Deposit and North Copper Zone. The depositional environment of the Talbot Property is similar to that of present and past producing base metal deposits of felsic to mafic volcanic and volcaniclastic rocks in the Flin Flon – Snow Lake Greenstone Belt.
Quality Control and Quality Assurance
Samples of half core are packaged and shipped directly from Rockcliff’s field office to TSL Laboratories (TSL), Saskatoon, Saskatchewan. TSL is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each bagged core sample is dried, crushed to 70% passing 10 mesh and a 250g pulp is pulverized to 95% passing 150 mesh for assaying. A 0.5g cut is taken from each pulp for base metal analyses and leached in a multi acid (total) digestion and then analyzed for copper, lead, zinc and silver by atomic absorption. Gold concentrations are determined by fire assay using a 30g charge followed by an atomic absorption finish. Samples greater than upper detection limit (3000 ppb) are reanalyzed using fire assay gravimetric using a 1 AT charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity. Rockcliff has no relationship with TSL other than TSL being a service provider to the Company.
Please view the updated power point presentation at www.rockcliffcoppercorp.com for additional information.
Rockcliff can earn a 51% interest in the Talbot Property from Hudson Bay Exploration and Development Company Limited (HBED), a wholly owned subsidiary of Hudbay Minerals Inc. by spending $6,120,000 on exploration expenditures over six (6) years. The first and second year expenditure commitments are $200K (completed) and $400K respectively with escalating expenditure commitments over the remaining years. The agreement provides that once Rockcliff has earned its 51% interest in the Talbot Property, Rockcliff (51%) and Hudbay (49%) will form a joint venture and Rockcliff will be the Operator of the joint venture. Provided Hudbay contributes its pro rata (49%) share of expenditures under the joint venture, it will have two (2) years from the date Rockcliff earns its 51% interest to purchase an additional 2% interest for a cash payment of $240,000 and either incurring expenditures over a two (2) year period equivalent to 2% of the joint venture expenditures made since the formation of the joint venture or paying such amount to Rockcliff in cash. If Hudbay acquires the additional 2%, it will become the Operator of the joint venture. Once a positive Feasibility Study has been completed and mining development has commenced, the Operator can increase its interest in the Talbot Property to 65% by paying the other participant a cash payment equal to the pro rata share of expenditures made by the other participant to reduce it to a 35% interest. The Operator would then fund the costs of development and will be reimbursed for 100% of the development costs including the 35% interest of the non-operator. Once the costs of development have been repaid, the parties will be reimbursed their pro rata share of expenditures made prior to the date development commences before net profits are distributed pro rata (please see Press Release dated April 23, 2014 and filed on SEDAR under Rockcliff Resources for additional information).
