Rambler Extends High Grade Copper Zone

13.62% Cu and 2.2 g/T Au over 6.56 feet

LONDON, ENGLAND and BAIE VERTE, NEWFOUNDLAND AND LABRADOR--(Marketwire - July 11, 2007) - Rambler Metals and Mining plc (TSX VENTURE:RAB)(AIM:RMM) is pleased to announce significant new results from its ongoing surface drilling program.

Two new drill hole intercepts have been discovered:

a) RM07-19e returned 6.56 feet of 13.62% copper with 2.2 g/T gold on the 1807 Zone. This reinforces the excellent copper grade of the 1807 Zone.

b) RM07-08c returns 11.98 feet of 2.94% copper with 19.0 g/T gold on the down plunge of the Ming Mine. The company is encouraged by the intersection in RM07-19e because it shows the potential for an elevated auriferous trend between this hole and RM05-08. (see Rambler Press Release 4 August 2005)

Ming Deposit and 1807 Zone

RM07-19e was drilled to test the 1807 Zone 100 metres up-plunge of past drilling. The hole is 25 metres across strike and to the southeast of RM07-19a, which also encountered high grade copper mineralization. (see Rambler Press Release 26 June 2007). The massive sulphide in this zone remains open at depth and will be a focus of future drilling.

RM07-08c targeted both the Ming Massive Sulphide Horizon (MMS) and the Ming Footwall Zone (MFZ) some 300 metres below the old mine workings. This massive sulphide intercept is 50 metres to the northwest of RM05-08, which also reported significant gold grades in multiple intersections (see Rambler Press Release 4 August 2005)

RM07-08c confirms the continuity of the thick copper bearing zone both down plunge and at depth. Drill testing will continue up-plunge to test MFZ continuity between RM07-08c and RM06-04l.

The Rambler project covers the historic Ming and Ming West copper-gold mines on the Baie Verte Peninsula where dewatering recently commenced. The dewatering/rehabilitation of the mine is anticipated for completion by the end of March 2008 and will provide the access required for a comprehensive underground drilling program.

An underground drilling contract has been awarded and is expected to begin at the end of 2007 Q3. This underground delineation drill program will run concurrently with the surface drilling program which is testing prospective areas proximal to the past producing mine.

Drill intercepts quoted are core lengths; true widths are estimated to be 90% to 95% of the intersected core lengths. National Instrument 43-101 compliance information regarding sampling and analytical protocols pertaining to the Rambler Project can be accessed via the following link: http://www.ramblermines.com

All tonnes are dry metric tonnes

Mineral exploration on the Rambler property is being conducted by RMM personnel.

All drill holes have produced 47.6 millimetre diameter (1.875-inch) NQ diamond drill core. The drill core is descriptively logged on site, aligned, marked for sampling and then split in half, longitudinally, using a diamond saw blade. One-half of the core is preserved in core boxes for future reference. The samples comprising the other half of the core are bagged, sealed and delivered directly to the analytical laboratory by RMM personnel. Base metal-bearing samples are nominally 1 metre to 1.8 metres (3.28 to 5.90 feet) in length except where specific geologic parameters require that a smaller interval be sampled. Samples with suspected precious metal content are nominally one metre or less, depending on the geological circumstances.

The sawed samples are delivered directly to Eastern Analytical Limited in Springdale, Newfoundland by RMM personnel where they are dried, crushed and pulped. Samples are crushed to approximately -10 mesh and split using a riffle splitter to approximately 300 grams. The sample split is pulverized using a ring mill to approximately 98% minus 150 mesh. In addition to regular samples, blank samples and quarter-split samples are also submitted for crushing/pulping.

The sample pulps are picked up directly at Eastern Analytical Limited by RMM personnel and returned to the project site at which point analytical standard samples and duplicate samples are inserted into the sample stream. The quality control procedures utilized by RMM have been approved by Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA). Their review was the basis of a technical report written by Scott Wilson RPA on the Rambler project conforming to NI 43-101 Standards of Disclosure for Mineral Projects. All sample rejects are also retrieved from Eastern Analytical by RMM personnel and securely stored by RMM.

The sample pulps are shipped by courier to Activation Laboratories Ltd. in Ancaster, Ontario for analysis. A typical analysis consists of three, industry-standard components:

(1) an aqua regia digestion followed by a 34 element ICP analysis,

(2) a gold assay consisting of a one assay ton fire assay with finish by atomic absorption, and

(3) an assay of specific base metals by aqua regia digestion followed by atomic absorption spectroscopy for those elements which exceed the limits of ICP accuracy.

Check assays for the Rambler project are being conducted by ALS Chemex, using industry-standard techniques posted on their website. Check assays are also routinely performed at Eastern Analytical Limited. The drill program and sampling protocol are being supervised by Mark Graves, P.Geo.; a Qualified Person as defined under the Canadian Securities Administrators' National Instrument 43-101.

Historical Estimates

For the Ming Mine, the most comprehensive historical estimates available derive from a review prepared in 1982 by D.M. Burton ("Burton"). In 1997 Canamera Geological Ltd. ("Canamera") was commissioned to do a feasibility study on the Rambler Property for Ming Minerals and drew heavily on Burton's work. Canamera reported remaining estimates on the property. Canamera concluded that the outlined mineral resource would not support an economically feasible operation. Note that these estimations and resources definitions are not in compliance with Canada's NI 43-101.

Burton (1982) classified the MFZ resources as "Possible". The other resources have not been classified by Canamera (1997). These estimates are historical estimates and which should not be relied upon. See the technical report on the Rambler property available at www.sedar.com for the full details and qualifications regarding these estimates.
