While there is currently 16,000 tonnes of 1806 gold ore remaining to be processed the recent exploration drilling results have outlined additional stoping blocks for future mining. Based on our projections gold processing should be completed by mid-May whereupon the Company will begin running low-grade copper ore through the concentrator as part of the start-up and commissioning process. Once the process has been optimized high grade copper ore from the 1807 zone will be fed through the mill. "Fiscal 2013 will be an important year for the Company as we aim to place the Company on a strong financial footing by executing our Phase I high grade low tonnage mine plan with a mind to continuing to identify opportunities for optimization and possible expansion beyond 2014." GOLD PRODUCTION Mining and processing of the 1806 zone have exceeded expectations with 9,714 ounces of gold poured to date. As mineralogical studies have indicated the gold is predominantly free and located on mineral grain boundaries, therefore easily liberated with an overall average recovery of 90%. The operations team at the mine and mill have done well with optimizing the early gold production for the Company. On average the mine has produced over 700 mtpd of ore (1100 ore/waste combined) and with the mill continually operating above 95% availability, its average daily throughput has been approaching 650 wet metric tonnes per day. Table 1 below summarizes gold production from the Ming Mine to date. Production from the 1806 gold zone is expected to continue up until mid-May whereupon the Company will changeover to copper concentrate production.

Gold pours occur every two weeks regardless of month end. ((i)Estimated value) Recent drilling of the high grade gold 1806 zone has confirmed the continuation of the zone up and down plunge. Several of the holes reported visible gold contained within and near the massive sulphides. This is a significant discovery for the Ming deposits in that it indicates the potential for more undiscovered high grade gold zones in or near the massive sulphide lenses. The presence of visible gold is encouraging as it confirms that the gold has been remobilized by later deformation and in contact metamorphic aureoles with later mafic dyke intrusions. In essence the mafic dykes could be a marker for visible gold when such dykes are present in or near the massive sulphides. The mafic dykes are well documented and mapped within the Ming Mine geological system. This theory will be tested and reported upon with further diamond drilling. The table below outlines the most recent assays from the exploration and delineation diamond drill programs.

Duplicate samples taken on all cut assays. All quoted intersections are core lengths; true widths are estimated to be 50-75% of core length. COPPER PRODUCTION The copper concentrator is ready for live ore and is scheduled to begin commissioning in May once the final ounces of 1806 ore have been processed and poured. Following a brief down period for mill cleanout the concentrator will first begin with approx. 15,000 tonnes of lower footwall material grading between 1% and 1.5% copper. It is important to commission the mill on this lower grade material so that no high grade copper is lost to tails while the reagent mix is optimized to recoveries in excess of 92% and while flotation operators gain experience with the new process. Once optimized the 1807 zone will be the first high grade ore to be blended and processed on its own. With the development of a dedicated haulage ramp and access headings already in place on the 338 lv, 346 lv and 361 lv, the Company is confident that concentrate production can be sustained once the plant has completed the commissioning phase and begun processing the high grade ore. Development of the 1807 zone on the 346 level is an important milestone for the Ming Mine project in that it is the first time that Rambler has had an opportunity to map and sample this zone from underground openings. Recent chip samples across the developed ore face have confirmed the high grade nature of the zone with grades returning 5.08% Cu, 0.94 g/t Au, 10.04 g/t Ag and 0.13% Zn over 3.50 meters. The 1807 access ramp below the historical 1600 level has also intersected a massive sulphide lens which has not been drill tested. The newly discovered massive sulphide lens is located on the hangingwall/footwall contact and recent chip sampling have returned 4.05% Cu, 4.08 g/t Au, 42.95 g/t Ag and 0.31% Zn over 1.50 meters. It is believed that the new lens may be the up plunge extension of the historical 1805 zone located approximately 100 meters down plunge. This zone has not been included in any of the Company's resource or reserve estimations. The table below summarizes the highlights of the development chip and muck sampling to date.

As a producing gold and copper miner, our objective is to become a mid-tier mining company by continuing the development of the Ming Mine, discovering new deposits and through mergers and acquisitions. The initial six years of the Ming Mine project is based on the underground mining of massive sulphides with a mineable reserve estimate of 1.498 million ore tonnes grading 1.62% copper, 2.40 g/t gold and 10.90 g/t silver (24,252 tonnes of copper, 115,549 ounces of gold and 525,139 ounces of silver of contained metal). All massive sulphide zones remain open both up and down plunge with the current exploration program focused on extending the known mineralization for inclusion in the resource/ reserve estimate. In addition to the outlined reserve estimate there is a sizeable footwall deposit, beneath the massive sulphide horizon, that has been outlined with an indicated resource grade of 18,306k tonnes grading 1.43% copper (261,258 tonnes of contained copper at a 1.00% copper cut-off grade). This zone forms the basis of the preliminary economic assessment, currently being compiled by the Company, which envisions the Ming Mine transitioning itself into a bulk tonnage mining operation. For further information on the Ming Mine project, please refer to the Company's NI 43-101 compliant technical reports, available under the Company's profile on SEDAR (www.sedar.com). Over the coming months and years, as the Company seeks to optimize the Ming Mine project into cash positive position, it is expected that future expansion into the footwall zone will be formalized with the goal of maximizing returns for shareholders and increasing the life of mine.
