Mr. Ken Lapierre reports

ROCKCLIFF EXPANDS TALBOT DRILL PROGRAM TO 7,500M INTERSECTS 5.6M GRADING 5.90% CUEQ INCLUDING 2.8M GRADING 9.9% CUEQ

Rockcliff Copper Corp. has released drill hole assay results from its continuing phase 2 drill program on the Talbot property, Manitoba. The Talbot property forms part of Rockcliff's Snow Lake project, which is located within the prolific Flin Flon-Snow Lake greenstone belt, Manitoba, Canada.

Ken Lapierre, president and chief executive officer, commented: "Diamond drilling at the gold-rich Talbot copper deposit continues to intersect significant high-grade mineralization, and the mineralization remains open in all directions. The deposit is comprised of multiple lenses, which is typical of large producing mines in the Flin Flon-Snow Lake mining camp. The drill program has now been expanded from 6,000 metres to 7,500 metres. We continue to focus on resource expansion of the deposit, as well as drill testing geophysical plates/anomalies recently discovered from the resurveying of historical drill holes."

Completed drill hole information from the company's continuing phase 2 drill program is found in the attached drill hole results table.

"(m)" equals metres and represents down-the-hole thickness as true thickness is not currently known.
"%" equals percentage.
"g/t" equals grams per tonne.
* Copper equivalent value used $2.50 (U.S.) per pound copper, $1,300 (U.S.) per troy ounce gold, 
$1.15 (U.S.) per pound zinc and $20 (U.S.) per ounce silver. One-hundred-per-cent metal recoveries 
were applied. Copper equivalent calculation is: CuEq equals copper grade plus ((zinc grade 
percentage divided by 100 times zinc price) plus (gold grade grams per tonne times gold price 
divided by gram) plus (silver grade grams per tonne gimes silver price per gram)) divided by copper
price times 100.
The numbers may not add up due to rounding.

TB-016 was drilled at UTM NAD83 co-ordinates 458511E/5997012N, to a depth of 1,028 metres, along an azimuth of 285 degrees and a dip of minus 70 degrees.

The gold-rich Talbot copper deposit is defined as a stratabound, gold-rich volcanogenic massive sulphide (VMS) copper deposit consisting of several multiple lenses of coarse-grained to stringer to massive sulphides consisting of pyrite, chalcopyrite, sphalerite and pyrrhotite in a quartzofeldspathic gneiss. The depositional environment is similar to that of present and past-producing base-metal deposits of bimodal volcaniclastic rocks in the Flin Flon-Snow Lake greenstone belt.

On Feb. 4, 2016, Rockcliff announced on the Talbot property an inferred mineral resource as set out in the National Instrument 43-101 (standards of disclosure for mineral projects) technical report dated Jan. 25, 2016, and titled "Technical report on the Talbot property, Manitoba, Canada," a copy of which is available on the company's SEDAR profile, 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 gold-rich Talbot copper deposit is detailed in the attached mineral resource statement table.

Notes:    
(1) Canadian Institute of Mining, Metallurgy and Petroleum 
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 per cent) using metal prices, estimated
recoveries and off-site payments. 
(3) Mineral resources are estimated using a long-term 
copper price of $3.50 (U.S.) per pound, gold price of
$1,450 (U.S.) per ounce, zinc price of $1.25 (U.S.) per 
pound and silver price of $22 (U.S.) per ounce. 
(4) A U.S.-dollar/Canadian-dollar exchange rate of 1.18 
was used.
(5) A minimum mining width of two metres was used.
(6) The average bulk density is 3.2 tonnes per cubic 
metre.
(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.

Laboratory quality assurance/quality control

Samples of half core are packaged and shipped directly from Rockcliff's field office to TSL Laboratories (TSL), Saskatoon, Sask. TSL is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each bagged core sample is dried and crushed to 70 per cent passing 10 mesh, and a 250-gram pulp is pulverized to 95 per cent passing 150 mesh for assaying. A 0.5-gram cut is taken from each pulp for base-metal analysis and leached in a multiacid (total) digestion and then analyzed for copper, lead, zinc and silver by atomic absorption. Gold concentrations are determined by fire assay using a 30-gram charge followed by fire assay gravimetric and an atomic absorption finish. Samples greater than an upper detection limit (3,000 parts per billion) are reanalyzed using a one AT charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity.

Rockcliff can earn a 51-per-cent interest in the Talbot property from Hudbay Minerals Inc. Please refer to the news release dated Oct. 11, 2016, for specific points of the option agreement.

Mr. Lapierre, PGeo, president and chief executive officer of Rockcliff, a qualified person in accordance with Canadian regulatory requirements as set out in NI 43-101, has read and approved the scientific and technical information that forms the basis for the disclosure contained in this press release.

About Rockcliff Copper

Rockcliff is a Canadian resource exploration company focused on the discovery, advancement and consolidation of the highest-grade unmined metal deposits in the prolific Flin Flon-Snow Lake (FF-SL) greenstone belt specifically centred on Snow Lake in Manitoba.
