Rockcliff Expands Tower Deposit Towards Untested Tower South Anomaly
11 Februar 2020 - 3:20PM
Rockcliff Metals Corporation (
“Rockcliff” or the
“Company”) (CSE: RCLF) (FRANKFURT: RO0, WKN:
A2H60G) is pleased to announce that the 2019 drill program
on its 100% owned Tower property has discovered a copper-bearing
extension to the existing Tower deposit. The discovery holes are
located immediately south and up to 200 metres (m) from drill holes
intersected in the Tower deposit. The copper rich massive sulphide
mineralization of the Tower deposit is traceable using
electromagnetic geophysical surveys. A similar, priority one
electromagnetic geophysical anomaly termed the the Tower South
Anomaly has been identified 700m south, and along strike of, the
Tower deposit. This high priority target remains untested and
is now drill ready.
A total of 26 holes totalling 11,030m were
completed in late 2019. Significant highlight assays within
the Tower deposit and along strike to the south of the Tower
deposit include:
- TB-045: yielded 13.28% CuEq across 4.15m
- TB-047: yielded 13.30% CuEq across 3.81m
- TB-049: yielded 8.34% CuEq across 2.34m
- TB-055: yielded 3.95% CuEq across 11.39m
- TB-058: yielded 8.71% CuEq across 4.84m
- TB-063: yielded 4.06% CuEq across 8.23m
Rockcliff’s President and CEO Alistair Ross
commented: “The extension of the mineralized zone by 200 metres to
the south and towards the high priority Tower South Anomaly,
especially finding thicker intersections near surface, bodes well
for the updated NI 43-101 resource estimate update currently
underway. The infill drilling also continues to confirm our
previous understanding of the deposit. We look forward to
completing the technical reports on the Tower, Talbot and Rail
deposits later in the first quarter of this year.”

m = metres represent down hole thickness as true
thickness is not currently known, g/t = grams per tonne, CuEq** =
copper equivalent values used: US$3.00 copper, US$1.15 zinc,
US$1400 ($45.02/gram) gold, US$20.00 ($0.64/gram) silver.
100% metal recoveries were applied. CuEq = Cu grade % + (Zn
grade % X Zn price per lb / Cu price per pound) + (Au grade
g/t X Au price per gram / Cu price per tonne) X 100 + (Ag grade g/t
X Ag price per gram / Cu price per tonne) X 100. Holes
TP-051 and TP-056 were not in the assay stream as they were used
100% for metallurgical and ore sorting studies. The numbers
may not add up due to rounding.
Drilling continues to confirm the high-grade
nature of the Tower deposit. Additional near surface drilling
intersected high-grade copper mineralization that extends the Tower
deposit 200m southward. Rockcliff’s geophysical surveys
(airborne, surface and bore-hole) have confirmed a high priority
exploration target, termed the Tower South Anomaly, located
approximately 700m south of the current limit of the Tower deposit.
Drilling is planned for the Tower South Anomaly and surrounding
area to determine the copper potential to the south of the Tower
deposit (see figure 1 below).
Presently, the Tower deposit is identified as a
remobilized, single, steeply dipping, high-grade, Volcanogenic
Massive Sulphide (VMS) lens that is located immediately below a
100m thick layer of Paleozoic limestone cover. The Tower deposit
consists of stringers and massive sulphide lenses of chalcopyrite,
pyrite, pyrrhotite and sphalerite. Drilling has intersected the
deposit and the extension mineralization over a strike length of
850m and to a vertical depth of up to 600m. The Tower deposit
remains open along strike and at depth. Within the property limits,
the Tower deposit and the Tower South Anomaly are associated within
a 12-kilometre-long arcuate trending magnetic horizon hosting
several additional untested conductive airborne targets considered
by the Company to be worthy of follow-up
exploration.

Notes:
- CIM definitions were followed for the estimation of mineral
resources.
- Mineral resources are estimated at a Cu cut-off of 0.5%.
- 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.
- Mineral resources are not mineral reserves and do not have
demonstrated economic viability.
- considered the Tower Copper Deposit to be reasonably amenable
to extraction using underground mining methods.
- There are no known factors related to permitting, legal, title,
taxation, socio-economic, environmental, and marketing or political
issues which could materially affect the mineral resource at the
time of reporting.
- The QP opinion (Generic Geo Inc.) is that the sample
preparation, security, analytical procedures, and collar, survey,
lithology and assay databases were adequate to be used for 3D
modelling and resource estimation after the QA/QC review was
completed and all issues were resolved. The quality of the drill
database used for the resource estimation was excellent.
The Mineral Resource estimatefor the Tower
deposit was prepared Mr. Kelly Malcolm P.Geo (APGO #2864) who
is an independent Qualified Person for the purpose of NI 43-101 –
Standards of Disclosure for Mineral Projects.

Quality Control and Quality Assurance
Samples of half core were packaged and shipped
directly from Rockcliff’s core facility in Snow Lake to TSL
Laboratories (TSL), in Saskatoon, Saskatchewan. TSL is a
Canadian assay laboratory and is accredited under ISO/IEC
17025. Each bagged core sample was 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 the 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.
Ken Lapierre P.Geo., Vice-President, Exploration
of Rockcliff, a Qualified Person in accordance with Canadian
regulatory requirements as set out in NI 43-101, has reviewed and
approved the scientific and technical information that forms the
basis for the disclosure contained in this press release.
