LONDON, ENGLAND and BAIE VERTE, NEWFOUNDLAND AND LABRADOR -- (Marketwired) -- 05/28/13 -- 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 and approved it accordingly. Mr. Pilgrim is an independent consultant contracted by Rambler Metals and Mining plc.

Tonnes referenced are dry metric tonnes unless otherwise indicated.

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.

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.
