- 7.4Mt of sub 2% mineralization in the Lower Footwall Zone excluded as a result of increasing the copper cut-off grade from 1.25% to 2.00% as it will not form part of the initial start-up mine plan. - 2,024,000t ore resource for the Ming Massive Zones in the measured and indicated categories; increased by 99% along with 1,498,000t in the inferred category (+28%). - 41,290t contained copper for the Ming Massives in the measured and indicated categories; increased by 52%. - 161,335oz total gold resource for the Ming Massives Zones in the measured and indicated categories; increased by 110% along with 98,740 Au oz in the inferred category (+86%). - 922,107oz total silver resource for the Ming Massives Zones in the measured and indicated categories; increased by 135% along with 450,673 Ag oz in the inferred category (+25%). Further details are available in Appendix 1 George Ogilvie, Rambler's President and CEO commented "Rambler has always believed that additional high grade resources including gold and silver could be added to the existing NI43-101 resource. The latest resource is significant in that we have been able to increase the tonnes, contained metal, gold and silver in the high grade massive sulphide zones. The high grade massive sulphide zones will form the basis for our initial mine plan which will be close to the historical production rate of 240,000 tonnes per annum. We believe this plan minimizes risk to Rambler shareholders by minimizing capital expenditures and maximizing profit margins during periods of low copper commodity prices. Upon completion of the project financing it is our intention to rapidly develop the Ming Massive Sulphide Zones bringing them into production in 2010. Upon the re-commencement of exploration diamond drilling additional resources will be forthcoming as all mineralized zones are open in all directions". FUTURE PLANS - Rambler is currently conducting a feasibility study on the Ming Mine that will target the high grade copper-gold massives sulphides as demonstrated in the latest NI43-101 Resource Estimate update. - Upon completion of the feasibility study Rambler will register the project with the appropriate government agencies to begin the process of environmental registration. - Rambler is currently engaged in discussions with a number of third parties, which it holds confidentiality agreements with, for the Project Financing. - Upon completion of the Project Financing, development and construction activities will begin to bring the Mine into production in 2010. - As the ore bodies are open in all directions exploration activity with the purpose of adding additional resources will recommence. A recent TITAN24 Geophysics DCIP and MT survey over Rambler's entire property revealed a number of new anomalies that require exploration drilling (see Rambler press release dated January 22, 2009) Mineral Resource Estimate for the Ming Massive Sulphide Horizon when compared to the previous reported NI43-101 Resource Estimate (30 April 2008) - 1807 Zone -- Upgraded 95,000 ore tonnes into the measured category; representing a 21% overall increase From 233,000t to 328,000t in the measured, from 108,000t to 105,000t in the indicated and from 32,000t to 20,000t in the inferred. -- 7% increase in tonnes of contained copper From 9,696t to 12,061t in the measured, from 5,064t to 4,621t in the indicated and from 1,354t to 638t in the inferred. -- 11% increase in gold oz From 14,428oz to 18,578oz in the measured, from 5,531oz to 5,793oz in the indicated and from 2,905oz to 921oz in the inferred. -- 27% increase in silver oz From 52,403oz to 74,007oz in the measured, from 23,552oz to 25,857oz in the indicated and from 6,540oz to 5,147oz in the inferred. - 1806 Zone -- A newly discovered gold rich Massive Sulphide Zone -- 349,000 ore tonnes added in the measured and indicated 267,000t in the measured, 82,000t in the indicated and 138,000t in the inferred. -- 2,118 tonnes of contained copper added in the measured and indicated 1,501t in the measured, 617t in the indicated and 1,022t in the inferred. -- 44,475 gold oz added in the measured and indicated 37,004 Au oz in the measured, 7,471 Au oz in the indicated and 8,733 Au oz in the inferred. -- 312,164 silver oz added in the measured and indicated 275,188 Ag oz in the measured, 36,976 Ag oz in the indicated and 37,097 Ag oz in the inferred. - Ming South Up Plunge -- A newly discovered Massive Sulphide Zone -- 135,000 ore tonnes added in the measured and indicated 94,000t in the measured, 41,000t in the indicated and 3,000t in the inferred. -- 4,290t tonnes of contained copper added in the measured and indicated 3,241t in the measured, 1,094t in the indicated and 46t in the inferred. -- 4,839 gold oz added in the measured and indicated 3,485 Au oz in the measured, 1,354 Au oz in the indicated and 159 Au oz in the inferred. -- 32,957 silver oz added in the measured and indicated 22,144 Ag oz in the measured, 10,813 Ag oz in the indicated and 1,009 Ag oz in the inferred. - Ming North and South Down Plunge -- 43% overall increase in ore tonnes From 252,000t to 463,000t in the measured, from 413,000t to 645,000t in the indicated and from 1,039,000t to 1,336,000t in the inferred. -- 50% increase in tonnes of contained copper From 4,729t to 7,803t in the measured, from 7,725t to 10,353t in the indicated and from 15,788t to 24,129t in the inferred. -- 64% increase in gold oz From 21,188oz to 29,741oz in the measured, from 31,875oz to 49,998oz in the indicated and from 50,093oz to 88,928oz in the inferred. -- 23% increase in silver oz; From 98,258oz to 150,906oz in the measured, from 166,283oz to 203,337oz in the indicated and from 354,326oz to 407,420oz in the inferred. Mineral Resource Estimate for the Stringer Sulphide Zones when compared to the previous reported NI43-101 Resource Estimate (30 April 2008) - Upper Footwall Zone -- 25,000 ore tonnes reduction, 1,698 tonnes contained copper reduction, 534 Au oz reduction and 5,047 Ag oz reduction all as a result of the new grade estimation parameters compiled by SRK Consulting. Although the new search parameters have increased significantly in the dip direction, the strike search ellipse has decreased by nearly 25%. - Lower Footwall Zone -- 7,402,000 ore tonnes reduction in the indicated category, 115,989 tonnes contained copper reduction, 16,975 Au oz reduction and 220,467 Ag oz reduction. All of these reductions were predominantly a result of Rambler increasing the cut-off grade in the Lower Footwall Zone to 2% Cu from 1.25% Cu cut-off in the previous reported NI43-101 Resource Estimate (30 April 2008) based on up to date NSR modeling and assumptions. With reference to the Lower Footwall Zone sensitivity tables, it should be noted that any increase in Cu commodity prices over the long term assumption of $1.92 /lb could potentially see cut-off grades reduced with a resulting increase in resources. It is Rambler's belief that the long term fundamentals for Cu remain strong and that $1.92 /lb represents a conservative estimate of long term Cu pricing.

(i) Mineral Resources are not Mineral Reserves and have not demonstrated
economic viability. All figures are rounded to reflect the accuracy of the
estimate. Cut off grades of 1.0 per cent copper for the massives, 1.25 grams
per tonne gold for the 1806 zone, 1.25 per cent copper for the upper
footwall zone and 2.00 per cent for the lower footwall zone are based on an
NSR model and metal prices of US$1.92/lb copper and US$800/oz gold, and
US$10/oz silver. Zinc does not contribute to the revenues.
Massive Sulphide Horizon (1807, 1806, North and South Zones) The copper-gold rich massive sulphides historically mined were the North and South Zones at 3.5% copper with 2.40 g/t gold. The zone averaged 3.7 metres in thickness with a strike length of 125 metres, plunging 30 degrees to the north east over 1500 metres. Mining took place from surface to the 2700 level (vertical feet) where ore was trucked to the shaft on the 1800 level. Rambler Metals and Mining's new drilling has extended the North and South Zone nearly 750 metres and the 1807 Zone 400 metres beyond the old property boundary. In addition to the down plunge extensions of these zones the Ming South has revealed a new resource up-plunge of any previously mined areas. This new resource is within 50m of the existing infrastructure and remains a target for future drill programs. The 1806 zone is a newly defined gold zone discovered during the underground diamond drilling program. This zone has added new gold ounces to the resource and will be an integral part of the initial 5 year start-up plan. As with all zones within the Ming deposit the 1806 Zone remains open downplunge and has the potential to significantly increase with additional drilling. Each of these zones is open at depth and remains a target for future exploration. The table below summarizes the copper grade sensitivities for the 1807 Zone: 1807 Zone - February 18, 2009

The Upper Footwall Zone was first discovered by Rambler Metals in 2006 where RM06-04f intersected 6.00 meters of 14.55% copper with 1.6 g/t gold. Although no new diamond drilling was drilled in this zone since the last resource estimate, the additional underground diamond drilling in the Lower Footwall has allowed SRK to better define the variography and search ellipses for all stringer type mineralization. For the Upper Footwall Zone only an indicated resource was estimated, the table below summarizes the copper grade sensitivities for this zone: Upper Footwall Zone - February 18, 2009

The Lower Footwall Zone has long been a target for a bulk tonnage mining method. Although with the current weak commodity prices the lower footwall zone does not form part of the initial 5 year start-up plan, this zone has the potential to add significant tonnes of copper when copper prices exceed US$2.00/lb. The new underground diamond drilling has allowed for better interpretation of the cross cutting mafic intrusives which in turn has impacted the overall quantity of ore tonnes. For the Lower Footwall Zone an indicated and inferred resource was estimated, the table below summarizes the copper grade sensitivities for this zone: Lower Footwall Zone - February 18, 2009

Resource classification Mineral resources for the Ming Mine have been classified according to the "CIM Standards on Mineral Resources and Reserves: Definitions and Guidelines" (December, 2005) by Larry Pilgrim, P.Geo, an appropriate Qualified Person as defined by NI43-101. Since this resource update did not have a 100% or greater change to the original resource there was no requirement for an Independent technical report or evaluation. A complete NI43-101 Technical Report will incorporate the resource estimation and methodology will be filed on SEDAR within 45 days after this press release. The resource estimation is based on a 3-D geological interpretation of the mineralized zones from 85,416 meters of RMM surface drilling (2003-2008) in 86 drill holes and 22,263 meters of RMM underground drilling (2007-2009) in 167 drill holes. The geological interpretation and modeling defined six separate but intimately related ore zones namely; the 1807 zone, the 1806 zone the Main Zone (includes North and South Ming), the Upper Footwall Zone and the Lower Footwall Zone. Density factors used to determine tonnages were 3.52 gcm3 for the 1807 Zone, 3.03 gcm3 for the 1806 Zone, 3.44 gcm3 for the Ming North and South Down Plunge, 3.35 gcm3 for the Ming South Up Plunge, 3.07 gcm3 for the semi-massive stringer Upper Footwall and 2.83 gcm3 for the stringer style Lower Footwall Zone. The modeled resources at Rambler were created using Datamine 3D modeling software with 5 x 5 x 5 m blocks. A sub-block routine was also applied with a minimum block size of 1.25 x 1.25 x 1.25 m. Grade estimation was conducted on data composited to 1m intervals, confined within the modeled mineralized zones. Appropriate grade cappings were applied to the composited data. Block grades were estimated using inverse distance squared (ID2) grade estimation methodologies. Normalized and regular variography used estimate search distance criteria was developed by SRK Consulting Engineers and Scientists with Isatis software for Cu, Au, Ag and Zn. A single spherical structure variogram (including a nugget effect) was constructed and fitted for each primary direction for all metals and input into the Datamine grade process. A complete copy of this report will be included with the NI 43-101 Technical Report. The classified resources for the various modeled mineralized zones at the Ming Mine have been tabulated for a range of copper cut-offs. The cut off applied to the massive ore is 1.00% copper, whereas the cut-off applied to the upper footwall zone 1.25% copper and the lower footwall zone is 2.00% copper. Metal prices of US$1.92/lb copper, US$800/oz gold and US$10/oz silver were applied. Zinc is reported but does not contribute to revenues. |
