United Silver Corp. announced that the Board of Directors has approved a phased, property-wide, USD 23 million, four-year plan to further explore and develop the Crescent Silver Mine resource. The objectives of the Plan are to further explore the existing silver resource, develop the existing resource, and explore for additional resources at the company's 80% owned Crescent Silver Mine. The Crescent Mine is located on a large, 365 hectare (902 acre) property in the heart of northern Idaho's Silver Belt, in the Coeur d'Alene silver-lead-zinc mining district. The Crescent Mine is situated between the world-class, previously-mined Sunshine silver mine and the Bunker Hill silver-lead-zinc mine, with previous district-wide production estimated to be over 1 billion ounces of silver, making it the second largest silver district in the world. Approximately 25 million ounces of silver at an average grade of 27.3 opt (SRK Consulting 43-101, March 1, 2010) were historically mined from the Crescent Mine, and known mineralization has been identified from near surface to approximately 5,000 feet depth below surface by the Bunker Hill Mining Company, prior owners of the Crescent Mine. The company consider this historical information to be reliable. Silver and base-metals-bearing vein deposits at Sunshine and Bunker Hill, located immediately to the east and west of, and adjoining, the past-producing Crescent Mine, were world-class deposits of silver. The Crescent Mine, which was a much smaller producer than the other two deposits, has never undergone a detailed and aggressive exploration program, despite the fact that the ore-bearing vein systems strike across the large, 365 hectare property, and are known to host high-grade silver-bearing vein deposits. The planned program at the Crescent is designed to aggressively follow up on known mineralization, and to produce silver-bearing concentrates from known mineralized bodies to fund the exploration of the depth and lateral extensions of the known mineralization. Very significant surface drilling and underground exploration in the form of a spiral ramp and drifting within the known mineralization closest to surface has already been completed. The objective of the current Plan is to restart, aggressively, this partially-completed exploration/development work which began in 2007. Highly-encouraging results from this earlier work form the basis for this aggressive exploration/development plan, which has the goal of unlocking what management believes is a very high potential for the delineation of a significant silver resource. The existing Hooper Level tunnel (2,725 feet elevation, see website for 3-dimensional view of underground workings) provides an excellent platform to test the down-rake extension of the South Vein resource. The South Vein resource, meanwhile, has been estimated to an elevation of 2,940 feet. Therefore, in 2011, a program of 12,000 feet of drilling to test the down-rake extension of the South Vein was proposed, of which only two holes totaling 1,449 feet of drilling were completed due to funding limitations. These two holes gave highly-encouraging results, indicating that the South Vein resource is open to depth and that further drilling is definitely warranted. A core loss of 6.5 feet between 718 and 728 feet in H-7 may have been from a mineralized, faulted zone within the South Vein. The H-6 intersection is at an elevation of 130 feet below and is 300 feet west of the lowest point of the limit of the calculated South Vein resource, and remains open to depth and along strike, indicating good potential for quickly expanding the known resource by further drilling. A decline to facilitate lateral drifting for underground exploration and eventual production activities, called the Countess decline, was collared by the Company in August, 2010 from a surface portal at 4,300 foot elevation and progressed for 2,400 feet to a point where it intersected the South Vein resource (as defined by SRK in their 43-101) at the 3,945 foot elevation. Test drifting along the South Vein structure at the 3,945 foot elevation began in March 2011 and, as of January 2012, a continuous 755 feet of strike length along the drift within the South Vein body yielded 10.4 opt silver over an average width of 9.2 feet. Management considers the Crescent to be a property with the potential for the delineation of a world-class silver-mineralized system. Factors on which this opinion is based include: The property sits between two world-class silver deposits and adjoins them both; Silver-bearing veins strike from the Sunshine mine, across the large Crescent land package, to the past-producing Bunker Hill mine; The Crescent deposit is a past-producing silver deposit where only limited exploration has been carried out; Drilling at Crescent has identified a near-surface resource while past mining at much greater depths indicates the potential for depth continuity; A small program of wide step-out, surface drilling has shown that silver mineralization continues well away from the known resource; Underground drilling has shown that known mineralization continues to depth and along strike and is open in both dimensions; Underground drifting has provided a platform for a much more extensive underground exploration program which has the possibility of identifying additional resources to depth and along strike.
