East-Side Drill Program Completed, Yields High Grade

VIRGINIA CITY, Nev., April 11, 2011 /PRNewswire/ -- Comstock Mining Inc. ("Comstock Mining" or "the Company") (OTCBB: LODE) announced the completion of Phase I drilling at the East-Side target in its Lucerne Resource Area. On April 6th, the final hole in this phase was completed. Assays have been returned from twelve reverse circulation (RC) holes, all showing significant mineralization, including hole E11-06 with two high grade gold assays (1.027 oz/ton; 35.17 g/t and 0.832 oz/ton; 28.49 g/t) separated by approximately 300 feet of depth and hole E11-12 with five feet of gold grading 1.04 oz/ton (35.62 g/t) in a 90 foot interval averaging 0.139 oz/ton (4.76 g/t). In addition, four of the holes reported significant intercepts containing silver grades in excess of one oz/ ton (34.25 g/t), including a five foot assay of silver grading 3.70 oz/ton (126.7 g/t).

The East-Side Phase I drilling campaign completed 27 RC holes totaling 19,774 feet (6,027 m). "The recent East-Side target results confirm our modeling efforts," says Larry Martin, the Company's Chief Geologist, "and is expanding the resource potential of the Project. We are planning additional drill campaigns to increase the density of drilling on the East-Side."  Larry continued, "The current, widely-spaced drilling has not yet found the limits of the mineralization.  Additional drill campaigns will define the mineralized envelope, but for now, each new hole that intercepts contiguous intervals of quartz veining adds to the exuberance of our team."

The East-Side target is the Company's designation for the portion of the Lucerne Resource Area to the east of State Route 342. It includes the Succor, Hardluck, Friendship, Brown, and Niagra patents, acquired in 2010 from the estate of William M. Donovan Jr. From a geological perspective, both sides are believed to be part of a continuous structural zone that continues below the road.  A series of northwest-trending, sub-parallel faults control the mineralization, which is further enhanced along the intersections with northeast-trending structures.

The Company has received assay results from the first twelve holes in the program. Significant mineralization (gold grade greater than 0.010 ounces per ton (0.34 g/t) or silver grades greater than 0.100 ounces per ton (3.42 g/t), and a length of at least ten feet (3.05 m)) occurred in all twelve of the newly reported holes. Hole E11-06 is particularly noteworthy for encountering two intervals of high grade gold: one at 565 feet with 5 feet of 1.027 oz/ton gold (35.17 g/t), contained in a longer, 85 foot interval averaging 0.151 oz/ton (5.17 g/t); and another at a depth of 875 feet with 5 feet of 0.832 oz/ton gold (28.49 g/t) and 3.700 oz/ton silver (126.71 g/t), in a longer, 190 foot interval averaging 0.085 oz/ton gold (2.91 g/t) and 1.044 oz/ton silver (35.75 g/t).   Other intercepts with silver grades over 1 oz/ton include 25 feet in hole E11-01, 55 feet in hole E11-07, and three intercepts totaling 60 feet in hole E11-12.  

Corrado De Gasperis, Comstock Mining's President and CEO, commented, "our recent assays of silver on the Dayton and now these findings on the East-Side quickly remind us why Nevada is called the Silver State: it was the historic silver mining of the Comstock that earned the nickname."

When combined with the seven holes drilled in 2010, the East-Side continues to demonstrate the pattern of mineralization predicted by the geological model. It is expected that the results from the remaining fifteen holes will continue this pattern. The results from the additional assays and a summary of the findings for the complete program will follow as soon as practically available.

Continued Drill Program

Immediately following completion of the East-Side, two drill rigs moved to the west side of State Route 342 for a drilling program to evaluate an extension of the planned Hartford/Lucerne starter pit to the north onto the Justice patent.  In addition, a third rig will begin Phase II of the Dayton drill program. Since the results from Phase I drilling on the Dayton were so positive, this additional program is designed to complete additional intermediate drill fences in preparation for a more detailed in-fill drilling program scheduled for later in the year.  Phase II will be a small, ten to twelve hole program that will take about four weeks to complete. Drilling priorities will then shift to delivering the final information required to enter production on the starter mine and prepare the heap leach facility.

"We are gearing up to begin production in 2011," De Gasperis concluded. "Although we will not lose sight of the exciting drilling in the Dayton, the East-Side and other targets, production is our focus and we look forward to commencing those activities. The additional Dayton phase will support future planning and a more substantive presentation of the resource in our next technical report."
