Rockcliff Metals Corporation (
“Rockcliff” or the
“Company”) (CSE: RCLF) (FRANKFURT: RO0,
WKN: A2H60G) is pleased to announce the completion of its
phase three drill program at the Company’s Bur property located in
central Manitoba. The Bur property hosts the historic Bur
zinc-copper deposit and is strategically located 22 kilometres by
road from Hudbay Minerals Inc.’s (“Hudbay”) copper-zinc
concentrator in the Snow Lake camp. The purpose of this drill
program was to locate additional mineralized areas proximal to the
historic Bur zinc-copper deposit.
Rockcliff is a major landholder in the Flin
Flon-Snow Lake greenstone belt which is the largest
Paleoproterozoic Volcanogenic Massive Sulphide (“VMS”) district in
the world hosting mines and deposits containing copper, zinc, gold
and silver.
Rockcliff’s President and CEO Alistair Ross
commented: “Our drilling has confirmed the presence of significant
zinc and copper mineralization along strike and at depth beyond the
historic Bur zinc-copper deposit. A phase four drill program
planned this winter will focus on higher grade VMS mineralized
areas proximal to the Bur zinc-copper
deposit.”

drill program are tabled below:

A report was prepared on the Bur Property in
2007. Rockcliff is treating the estimate of mineral resources on
the Bur Zinc-Copper Deposit Report as an “historical estimate”
under NI 43-101 and not as a current mineral resource.

____________________________________________________________________________
Notes: 1. CIM definitions were followed for the estimation of
mineral resources. 2. Mineral resources are estimated at a zinc
equivalent cut-off of 5%. 3. Cut-off grade was based on a zinc
price of US$1.15 per pound and a copper price of US$2.35 per pound.
4. Given the tonnage, grade and orientation of the deposit, AMEC
considered the Bur Deposit to be reasonably amenable to
extraction using underground mining methods. 5. Specific Gravity
measurements used to estimate the mineral resource tonnes ranged
from 2.64 to 3.74 with an average of 3.16. 6. A minimum mining
width of 3 metres was used. 7. Mineral resources are not mineral
reserves and do not have demonstrated economic viability. 8. The
deposit was documented in a report dated October 1, 2007 and titled
“Bur Project, Snow Lake Manitoba, Canada NI 43-101 Technical
Report” (the “Bur Deposit Report”). The report was prepared for
Hudbay by AMEC and was filed on Hudbay’s SEDAR profile on January
31, 2008.
Historical estimates of grade and tonnage
disclosed in this press release are viewed as reliable and relevant
based on the information and methods used at the time. The 2007 NI
43-101 Bur Deposit Report was prepared in compliance with
resource definitions under NI 43-101 but must be considered only as
historic resources as neither Rockcliff nor its Qualified Persons
have done sufficient work to classify the historic estimate as a
current mineral resource under current mineral resource or mineral
reserve terminology and are not treating the historic estimate as a
current mineral resource. The historic resource should not be
relied upon. Additional work including surface geophysics, drilling
and bore hole geophysics will need to be completed to upgrade the
historical resource to current.
The historical Bur zinc-copper deposit is a
stratiform, distal, massive sulphide VMS deposit that occurs within
a narrow turbidite assemblage of interbedded metagreywacke,
metasiltstone and graphitic meta-argillite in a basinal area
situated between two granitic intrusions. The northeast striking
deposit dips 60-70 degrees northwest, ranges from <0.3metres up
to 5 metres thick with a known lateral extent of approximately
4,500 metres. Historic and recent drilling throughout the Bur Zinc
Property has encountered disseminated, semi-massive and massive
sulphide mineralization below overburden along a strike length of
over 8,000 metres and to a vertical depth of 950 metres.
Mineralization consists of sphalerite, chalcopyrite, pyrrhotite,
pyrite, galena and arsenopyrite. The Bur zinc deposit contains up
to 20% felsic or cherty nodules consisting of wall-rock and late
quartz fragments displaying a brecciated texture to the
mineralization. The Bur zinc-copper deposit remains open in all
directions.
Rockcliff is earning a 100% interest from Hudbay
by spending $3.0M over a 4 year period on the Bur property.
Presently, Rockcliff has completed approximately $2.5M in
expenditures. Please refer to the Company’s news release dated
September 26, 2016 for specific terms of the option agreement
Quality Control and Quality
Assurance
Samples of half core were packaged and shipped
directly from Rockcliff’s field office 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.

Canadian regulatory requirements as set out in NI 43-101, has read
