Rockcliff Drilling Intersects High Grade Copper at Dickstone, 3.0% copper, 0.2g/t gold, 0.2% zinc, 9.2g/t silver over 2.3m

Large Strong Conductive Anomaly Associated with Mineralization

Trading Symbol RCR: TSXV

TORONTO, March 4, 2013 /CNW/ - Rockcliff Resources Inc. (RCR: TSXV) is pleased to announce that drilling has intersected high grade copper mineralization at its Dickstone Property.

Drill hole RDS13-003 intersected 2.2% Copper, 0.1g/t Gold, 0.3% Zinc, 7.0g/t Silver across 3.3m including 3.0% Copper, 0.2g/t Gold, 0.2% Zinc, 9.2g/t Silver across 2.3m

The high grade copper intersection is associated within a large, flat plunging, virtually untested DPEM and bore hole anomaly measuring a minimum 250m wide by 800m long.  Additional geophysics will be completed to determine the limits of the anomaly and where the anomaly is strengthening.

High grade copper mineralization of hole RDS13-003 is associated with massive sulphides consisting of pyrrhotite, chalcopyrite, pyrite and sphalerite within a bimodal altered host rock ranging from rhyolitic to mafic in composition.  Last year's drill hole RDS12-002 also intersected the bottom edge of the same sulphide anomaly approximately 170m below the bottom of the mine workings and approximately 100m north of hole RDS13-003.  It intersected 2.7% copper, 0.4g/t gold, 0.3% zinc, 8.6g/t silver across 2.5m. Please refer to the press release dated June 5, 2012 for additional information or visit

Significant assay results from drill hole RDS13-003 which have been received from the analytical laboratory are tabulated below. The lengths reported are drill intersected core lengths and do not represent true widths.

To (m) Length
Cu% Au g/t Ag g/t Zn%
589.85 593.15 3.3 2.2 0.1 7.0 0.3
590.85 593.15 2.3 3.0 0.2 9.2 0.2

The high grade copper mineralization represents the down dip continuation of the Dickstone Copper Deposit (Dickstone #1).  The flat plunging anomaly intersected in holes RDS12-002 and RDS13-003 is located below the steeply plunging mine workings and represents a potential change in the geometry of the copper deposit and a new area with significant copper potential not previously identified.

The Dickstone Deposit was discovered in 1936 and production began in 1970 from two VMS-rich zones (one copper, the other zinc).  Two-350m deep production shafts hoisted ore between 1970 and 1975.  The mine was shut down due to low commodity prices.  Combined five year production figures are tabulated below.

Tonnes Copper/pounds Zinc/pounds Silver/ounces Gold/ounces
775,210 2.46%/42,000,000 3.12%/53,000,000 12.50g/t/311,000 0.34g/t/8,500

At closure in 1975, the following additional historical resources were present below the underground workings at the Dickstone Mine:

Deposit Tonnes Copper Zinc Silver Gold
Dickstone #1 143,800 3.29% 0.60% 7.5g/t 0.20g/t
Dickstone #2 164,900 1.50% 7.10% 13.4g/t 0.40g/t

Both the copper (Dickstone #1) and zinc (Dickstone #2) rich deposits are open at depth.  The historical resources were documented in the 1975 annual report for Dickstone Copper Mines Ltd. and in the Mineral Deposit Series completed by the Manitoba Energy and Mines Geological Services in 1996. Although the resources are viewed as reliable and relevant based on the information and methods used at the time they do not satisfy the requirements set out by NI 43-101.  Neither Rockcliff nor its Qualified Persons have done sufficient work to classify the historical estimates as current mineral resources and are not treating the historical estimates as current mineral resources.  The historical resources should not be relied upon.

Rockcliff has the exclusive right to earn a 100% interest in the Dickstone Property from Xstrata Copper Canada, a division of Xstrata Canada Corporation (Xstrata).  Rockcliff will be required to incur aggregate exploration expenditures totaling $3,500,000 over four years.  If Rockcliff earns a 100% interest in the Dickstone Property, Xstrata then has a right to acquire up to a 70% interest in the Dickstone Property.  Please refer to the press release dated February 22, 2011 for further details.

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.

The information in this news release has been reviewed and approved by Ken Lapierre P.Geo., President and CEO of Rockcliff Resources Inc., a Qualified Person in accordance with Canadian regulatory requirements as set out in NI 43-101.
