Thundermin Obtains New Joint Venture Partner as Rambler Metals Purchases 
Cornerstone's 50% Interest in the Little Deer Copper
TORONTO, ONTARIO -- (Marketwired) -- 09/17/13 -- Thundermin Resources
Inc. ("Thundermin") (TSX:THR) announces that it has declined to
purchase Cornerstone Capital Resources Inc.'s ("Cornerstone") 50%
interest in the Little Deer Copper Project ("Little Deer") situated
approximately 10 km north of Springdale in north-central
As a result, Thundermin has been advised by Cornerstone that
Cornerstone has entered into a letter of intent with Rambler Metals
and Mining Canada Limited ("Rambler"), a 100% owned subsidiary of
Rambler Metals and Mining plc., to purchase Cornerstone's 50%
participating interest in Little Deer. The purchase price is
$550,000, being $200,000 in cash and $350,000 in common shares of
Rambler plus a 0.75% net smelter return royalty on Cornerstone's
proportionate share of all products produced from any future mine at
Little Deer. Rambler's offer is subject to a full due diligence
review and negotiation and agreement on final terms and conditions
which must be completed on or before November 14, 2013. Should
Rambler and Cornerstone complete the transaction on Little Deer, then
Rambler will be bound by the terms of the current
Thundermin-Cornerstone Joint Venture Agreement under which Thundermin
has the right to increase its interest in Little Deer to 75%. 
John B. Heslop, President and Chief Executive Officer of Thundermin
said "we are looking forward to working with Rambler on the Little
Deer Copper Project. Rambler has successfully brought the
past-producing Ming Mine in Newfoundland back into commercial
production. It is hoped that Rambler's mining expertise will also
lead to the resurrection of the Little Deer and Whalesback copper
deposits in the future if they are viable. The Little Deer and
Whalesback copper deposits are in close proximity to Rambler's port
facilities at Goodyear's Cove which could allow the possibility of
bulk shipping of material to their Nugget Pond Processing Facility
thus minimizing both future capital and operating costs at Little
The Little Deer copper project, located approximately 10 km north of
Springdale in north-central Newfoundland, hosts the Little Deer and
Whalesback copper deposits. On June 22, 2011 and July 26, 2012,
National Instrument 43-101 ("NI 43-101") compliant mineral resource
estimates, which were undertaken by P&E Mining Consultants Inc.
("P&E") of Toronto, Ontario, were announced for Little Deer and
Whalesback, respectively. P&E estimated that Little Deer contains
Indicated Resources of 1,911,000 tonnes ("t") at an average grade of
2.37% Cu (99.8 million lbs. Cu) and additional Inferred Resources of
3,748,000 t at an average grade of 2.13% Cu (176.0 million lbs. of
Cu). P&E estimated that Whalesback contains Indicated Resources of
797,000 tonnes grading 1.67% Cu (29.3 million lbs. Cu) and Inferred
Resources of 443,000 tonnes grading 1.57% Cu (15.3 million lbs. Cu).
On a combined basis, Little Deer and Whalesback are estimated to
contain Indicated Resources of 2,708,000 tonnes grading 2.16% Cu
(129.1 million lbs. Cu) and Inferred Resources of 4,191,000 tonnes
grading 2.07% Cu (191.3 million lbs. Cu).  
On November 1, 2011, results of a positive Preliminary Economic
Assessment ("PEA") for the Little Deer copper deposit, on a
stand-alone basis, were announced that indicate that there is
potential to develop the Little Deer copper deposit on an attractive
economic basis at current copper prices. The discovery of new copper
resources at Whalesback during 2012, because of their proximity to
Little Deer, expand the total mineral resources available for mining
and may enhance the overall economics of establishing a new mining
operation at Little Deer. 
Qualified Persons  
The NI 43-101 mineral resource estimates and PEA referred to above
were prepared under the supervision of Mr. Eugene J. Puritch, P.
Eng., President of P&E. Mr. Puritch is an independent Qualified
Person ("Q.P.") in accordance with NI 43-101.  
Mr. Andrew Hussey, P.Geo., is the Q.P. responsible for supervising
all of the drilling programs at Little Deer and Whalesback for the
purposes of NI 43-101.
