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