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.
