Rambler's Strategic Partner Releases Its First NI43-101

Resource Estimate on the Green Bay Property Group

LONDON, ENGLAND and BAIE VERTE, NEWFOUNDLAND AND LABRADOR--(Marketwired - May 28, 2013) - Rambler Metals and Mining plc
(TSX VENTURE:RAB)(AIM:RMM) ('Rambler' or the 'Company') would like to announce that its Strategic Partner, Maritime
Resource Corp. (TSX VENTURE:MAE) ('Maritime') has released its first NI43-101 compliant resource estimate encompassing
the entire Green Bay Property group, located in Newfoundland and Labrador, Canada. Maritime holds 100% of the Green Bay
Property which hosts the former producing Hammerdown Gold Mine and the newly discovered Orion deposit.

A copy of Maritime's press release has been attached in its entirety under Appendix 1. For more information on the Green
Bay Property group please visit Maritime's website at www.maritimeresourcescorp.com. A technical report is being
prepared and will be filed with SEDAR within 45 days.

George Ogilvie, President and CEO, comment:

     "We are pleased to see our Strategic Partner, Maritime Resources,
     advancing this project forward with its first NI43-101 resource
     estimate. Rambler's investment in Maritime was partly based on the
     potential of the Hammerdown Gold Mine and it's synergies with our
     own Nugget Pond milling facility, where the ore from Hammerdown
     was formerly processed between 2000 and 2004.

     In many ways the Hammerdown Gold Mine resembles the Ming Mine
     before it was dewatered and brought back into production. The
     increase in resource ounces on the Orion deposit is also
     encouraging as it may add new flexibility to the potential of the
     property group.

     We look forward to continuing to build on our strategic
     partnership with Maritime."

ABOUT MARITIME RESOURCES CORP.

Maritime Resources holds a 100% interest in the Green Bay property group which hosts the past producing Hammerdown gold
mine, the Orion gold deposit, separated by a 1.5 km distance, and the Lochinvar base / precious metals deposit.

Hammerdown itself was successfully mined by Richmont Mines between 2000 and 2004 with gold prices averaging $325 US per
ounce. During its operation a total of 291,400 tonnes of ore were mined and milled, at an average head grade of 15.83
g/t gold, recovering a total of 143,000 ounces during its life. All ore was processed at the Nugget Pond mill, now owned
and operated by Rambler Metals and Mining, with an average gold recovery of 97.1%. Mining concluded in 2004 due to low
gold prices with mineralization remaining, although uneconomic at that time. The Orion gold deposit consists of two main
vein systems, both of which are open along strike, up and down plunge.

Larry Pilgrim, P.Geo., is the Qualified Person responsible for the technical content of this release and has reviewed

Maritime Releases First NI 43-101 Resource Estimate for Green Bay Gold Property, Newfoundland

Maritime Resources Corp. (TSX VENTURE:MAE) ("Maritime" or the "Company") - is pleased to announce that the Company has
received the initial independent NI 43-101 Mineral Resource Estimate for its 100% owned Green Bay Gold property near
Springdale, Newfoundland. The mineral resource for the property is estimated to contain in excess of 400,000 ounces of
gold in the Measured and Indicated category, using a 3 g/t cut-off grade, and in excess of 600,000 ounces in the
Inferred category, also at a 3 g/t cut-off grade.

The estimate was compiled by Tetra Tech and includes all newly discovered gold mineralization resulting from the 2011
and 2012 exploration programs in addition to any un-mined deposits on the Green Bay property that remain from previous
operation. The property consists of the former Hammerdown Mine (developed between 2001 and 2004), including the
Rumbullion and Muddy Shag zones in the north, and the Orion deposit situated 1.5 km to the south. The effective date of
the Mineral Resource Estimate is May 23, 2013.

Eric Norton, President and CEO, comments:

     "We are extremely pleased to have completed this maiden Mineral
     Resource Estimate. The resource model is robust and incorporates
     all historic as well as new drilling results. The uniquely
     appealing aspects of this project are the high grades of the
     veins, the accessibility of the deposit from surface, including
     access to the existing underground ramp system, and excellent
     local infrastructure including roads, power and fresh water to the
     site. It is particularly satisfying to see that the overall grade
     of the Hammerdown deposit is relatively insensitive to the
     selection of the cut-off grade.

     Our exploration activity completed in 2012 demonstrated that the
     deposit remains open along strike, and the Company is confident
     that there is potential for this estimate to increase with further
     work. The 3D modelling that has now been completed will help guide
     future drill programs by highlighting strategic drill targets that
     can hopefully add new ounces, or upgrade resource categories."

The Mineral Resource Estimate incorporates 724 historic drill holes from which over 16,000 gold assay samples were
collected. Recent work includes over 3,700 metres of diamond drilling in 11 holes at Orion in 2011 and 2,500 metres in
16 holes drilled at Hammerdown in 2012. The 2012 exploration program also trenched and exposed 120 metres of the
Rumbullion vein system at surface where 445 channel samples were taken from 37 channels cut at strict three metre
intervals. Work was curtailed due to the onset of winter weather, but the veins remained robust at the eastern extremity
and are available for further follow-up work and sampling.

1.  CIM definition standards were followed for the resource estimate.
2.  The 2013 resource models used Ordinary Krig grade estimation within a
    three-dimensional block model with mineralized zones defined by
    wireframed solids.
3.  A cut-off grade of 3.0 g/t Au over 1.2 metres was used for reporting
    resources with capping of gold grades at 125 g/t at Hammerdown and 50
    g/t at Orion.
4.  A Specific Gravity of 2.84 was applied.
5.  Numbers may not add exactly due to rounding.
6.  Mineral Resources, which are not mineral reserves, have not demonstrated
    economic viability.
7.  The quantity and grade of reported inferred resources in this estimation
    are uncertain in nature and there has been insufficient exploration to
    define these inferred resources as an indicated or measured mineral
    resource and it is uncertain if further exploration will result in
    upgrading them to an indicated or measured mineral resource category.
8.  A portion of the estimated resource, specifically the Hammerdown
    mineralization, may be located in close proximity to previously mined
    areas and, as such, may not be recoverable due to structural or safety
    concerns.

The Resource Estimate was prepared by Todd McCracken, P. Geo. of Tetra Tech, Sudbury, ON. Mr. McCracken is a qualified
person and independent of the Company, as defined by section 1.5 of NI 43-101.The mineral resource estimate is based on
the combination of geological modeling, geostatistics and conventional block modeling using the Ordinary Krig method of
grade interpolation. The mineral resources were estimated using a block model with parent blocks of 5m X 5m X 5 m split
three times into sub -blocks. The geological model including mineralized intercepts were generated by Maritime personnel
and then audited by Tetra Tech. The QAQC protocols and corresponding sample preparation and shipment procedures have
been reviewed by Tetra Tech.

A technical report is being prepared and will be filed on SEDAR in the next 45 days.

ABOUT MARITIME:

Maritime Resources holds 100% of the Green Bay property which hosts the past producing Hammerdown gold mine and the
Orion gold deposit separated by a 1.5 km distance, and the Lochinvar base metals/precious metals deposit.

The Hammerdown gold deposit was successfully mined by Richmont Mines between the years 2000 and 2004 while gold prices
averaged $325/oz. During its operation a total of 291,400 tonnes of ore were mined and milled, at an average grade of
15.83 g/t Au, recovering a total of 143,000 ounces of gold. All of the ore was processed at the Nugget Pond mill, now
owned and operated by Rambler Metals, with an average gold recovery of 97.1%. Mining concluded in 2004 due to low gold
prices with mineralization remaining, although uneconomic at that time. The Orion gold deposit consists of two main vein
systems, both of which are open along strike, up and down plunge.

Maritime would like to acknowledge the financial support provided by the Junior Exploration Assistance Fund granted by
the Government of Newfoundland and Labrador's Department of Mines and Energy.

A map of the Green Bay property showing the location of the gold deposits and local infrastructure are available, along
with additional information regarding the Resource Estimate, at the Company's website (www.maritimeresourcescorp.com).
