TORONTO, ONTARIO-- Rockcliff Resources Inc. (TSX VENTURE:RCR) is pleased to
announce that it has received an independent - Mineral Resource Estimate
prepared by Mr. Jason Baker P.Eng. (APENS#9627), a Geological Engineer with
Caracle Creek International Consulting Inc. (Caracle Creek) for the T-1 Copper
Deposit located on the Tower Property, central Manitoba.

The Mineral Resource Statement prepared by Caracle Creek for the T-1 Copper
Deposit is detailed below.

Indicated     1,084,186    3.73      1.05     17.28      0.55      88,968,303

Notes:
1. CIM definitions were followed for the estimation of mineral resources.
2. Mineral resources are estimated at a Cu cut-off of 0.5%.
3. Cut-off grade was based on a copper price of US$3.63 per pound.
4. Given the tonnage, grade and orientation of the deposit, Caracle Creek
considers the T-1 Copper Deposit to be reasonably amenable to extraction using
underground mining methods.
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.
6. Mineral resources are not mineral reserves and do not have demonstrated
economic viability.

Ken Lapierre, President and CEO commented, "The NI 43-101 Resource Estimate is
our first estimate on the T-1 Copper Deposit. The deposit remains open in all
directions, has exceptional grades, is continuous, predictable and has the
potential for significant expansion with additional drilling. Rockcliff plans
in early 2013 to advance the deposit's potential by initiating a metallurgical
study as well as drill test along strike and at depth. Additionally, with the
recently discovered T-2 Copper Zone and highway and power line within 500m of
the deposit, we remain extremely bullish that additional copper resources on
this property will be achieved in close proximity to excellent
infrastructure".

The Indicated and Inferred Mineral Resource for the T-1 Copper Deposit was
classified according to the CIM Definition Standards for Mineral Resources and
Mineral Reserves (December 2005) by Mr. Jason Baker P.Eng. (APENS#9627), who
is an appropriate independent person for the purpose of National Instrument
43-101. Mr. Baker has reviewed and approved the technical content of this news
release.

The T-1 Copper Deposit is a remobilized, single, vertical dipping, high grade,
VMS lens that is located immediately below a 100m thick layer of Paleozoic
limestone cover. It consists of stringers and massive sulphide lenses of
chalcopyrite, pyrite, pyrrhotite and sphalerite. Drilling has intersected the
deposit over a strike length of 800m and to a vertical depth of up to 600m.
The Deposit mineralization remains open along strike and at depth where
surface (DPEM) and bore hole geophysics have indicated a continuation of the
sulphide conductivity beyond the limits of the resource. The deposit is
associated with a 12km long accurate copper horizon hosting a second zone of
copper mineralization (T-2 Copper Zone) and several additional conductive
targets worthy of follow up exploration.

Resource Estimation Methodology

The drill hole database used for the resource estimation consisted of 41 drill
holes assembled and validated by Caracle Creek. A total of 1098 assay
intervals from 41 drill holes were imported into Gems 6.4 software. Thirty
three holes were used for the resource estimation while the remaining eight
holes were along the edge of the deposit and were either not mineralized or
contained weak mineralization not meeting the Cu (ppm) cut-off of the 5,000ppm
criteria. There were two major drilling campaigns completed, the first in
2000-2001 (Falconbridge) and the second in 2010-2012 (Rockcliff). The mineral
resource was estimated using Gems 6.4 software with an origin at 486270m
Easting, 5980365m Northing and 320m elevation. Block dimensions of 5m by 5m by
5m were selected based on volume variances analyses. The interpolation of the
composited assay data was completed using an inverse distance cubed method of
interpolation with two passes. This is the first Mineral Resource Estimate for
the T-1 Copper Deposit reported in accordance with Canadian Securities
Administrators National Instrument 43-101 and was estimated in conformity with
generally accepted CIM "Estimation of Mineral Resource and Mineral Reserves
Best Practices Guidelines". The mineral resource was classified as Inferred
and Indicated. Classification includes copper, zinc, silver and gold data.

Extent to Which Estimate of Mineral Resource may be Materially Affected by any
Known Relevant Issues.

Neither Rockcliff's Qualified Person, Ken Lapierre, nor Caracle Creek's
Qualified Person, Jason Baker, nor Management of Rockcliff is aware of any
known environmental, permitting, legal, title, taxation, socio-political,
marketing or other relevant issues that may materially affect the estimate of
the mineral resource.

A complete Technical Report, compiled in accordance to Canadian Securities
Administrators National Instrument Form 43-101 Guidelines, will be filed on
SEDAR within 45 days of release of this press release.

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, is responsible for the information in this press release.

Pursuant to an exploration and option agreement with Pure Nickel Inc., to earn
a 70% interest in the property, Rockcliff must pay $150,000 in incremental
payments and is required to incur aggregate exploration expenditures totalling
$4,000,000.

Rockcliff has recently exercised the option to earn its 50% interest by
spending $2,000,000 on exploration expenditures and paying $90,000 to Pure
Nickel Inc. over the last two years. Both parties will now form a joint
venture and Rockcliff will earn an additional 20% in the property by spending
an additional $2,000,000 (in progress) in exploration expenditures and paying
a total of $60,000 over the next 2 years. Once completed, Rockcliff will
control a 70% interest in the property. An underlying 2% NSR on the property
is held by Xstrata Nickel, of which half can be purchased for $1,000,000.
