COMSTOCK MINING UPDATES NI 43-101 TECHNICAL REPORT

M&I RESOURCE INCREASES to 2.15 MILLION GOLD-EQUIV OUNCES,

LUCERNE M&I INCREASES 25%, WITH NEWLY DISCOVERED CHUTE ZONE

Virginia City, NV (February 7, 2013) -- Comstock Mining Inc. or “the Company” (NYSE MKT: LODE) announced today the highlights of its fourth National Instrument 43-101 (NI 43-101) technical report (the “2013 Report”, or the “Report”) authored by Behre Dolbear & Company (USA), Inc. of Denver Colorado. The Report declared a mineral resource estimate for the Comstock Mine Project in Storey and Lyon Counties, Nevada, of Measured and Indicated Resources containing 1,824,000 ounces of gold and 17,100,000 ounces of silver, for a total of 2,150,000 gold equivalent ounces[1], and an estimate of an Inferred Resource containing an additional 870,000 gold equivalent ounces. These estimates include the newly identified Chute Zone, a wedge-like, structurally bounded zone that hosts significant gold and silver. The Report also includes an additional 200,000 gold equivalent ounces outside of the modeled area, in the Historical Resource Category.

Comstock Mining Inc.’s Chief Executive Officer, Corrado De Gasperis commented, “Discovery of the East-side Chute Zone and the better than expected increase of Measured and Indicated Resource in Lucerne is tremendously rewarding for our team. Quantifying over 3.2 million gold-equivalent ounces, on just a fraction of our land position, provides us with significant confidence in the long-term future of the Lucerne Mine and our overall resource goals.”

The 2013 Report incorporates the results of the Company’s 2012 drilling program, which ran from January 25, 2012 through December 7, 2012. The program focused on infill and development drilling in the Lucerne Resource area, comprised of 391 holes totaling 146,274 feet. The drilling program consisted of 364 reverse circulation (RC) holes, totaling 138,521 feet, and 27 core holes, totaling 7,754 feet. The drilling totals also included fourteen widely-spaced exploration holes in Spring Valley (previously announced in a May 9, 2012 Press Release) and 22 step-out and infill holes in the East Side target (previously announced in a November 7, 2012 Press Release). The total cost of the program was $4.87 million, with an average cost per foot of $33.26.

The 2013 Report comments, “Behre Dolbear believes the Comstock Mine Project represents a well-explored epithermal precious metal deposit within a world-class mining district… The geology of the project area is well described and understood through vigorous surface mapping and drill hole logging. The density of geologic data is high and the reliability is excellent, particularly in the various Lucerne Mine areas.”

The Report also comments on the Company’s completely redesigned and rebuilt processing facility, and the operating results through the end of 2012. The Company estimates that the heap leach ultimate recovery will average over 70% for gold and over 45% for silver.

Lucerne Area Details

The Lucerne Resource Area includes the previously operated Lucerne, Hartford, and Billie the Kid pits; the historic Justice and Keystone surface cuts and underground mines; and the historic Woodville bonanza. The modeled mineralization covers approximately 5,400 feet of strike length. The Lucerne Resource Area is also host to the Company’s Lucerne Mine, opened in 2012, with an associated heap leach and Merrill-Crowe processing facility.

The Lucerne development drilling directly supported the start-up of the Lucerne Mine, extending the life of the mine plan, and confirming the continuity of the mineralization.

Chute Zone Discovery

Although the Company drilled a limited number of East-side holes, the results led to the discovery and interpretation of the “Chute Zone” by Company geologists. This intersection between the northwest striking and northeast dipping Silver City fault, and a series of northeast striking and southeast dipping structures hosts a zone of enhanced mineralization. The zone consistently averages 0.095 ounces of gold per ton over drill intercepts of 50 to 270 feet, and has currently mapped dimensions of 100 to 150 feet by 100 feet by 450 feet.

“Since 2008, our geologists have recognized the enhanced grades of precious metals when northeasterly striking mineralized structures intersected the Silver City fault zone,” stated Larry Martin, VP of Exploration and Mine Development. “Now we have identified a specific, wedge-like, structurally bounded zone that hosts significant gold and silver, which we are calling the ‘Chute Zone’. The geometric shape is similar to high grade zones historically mined in the Comstock district as bonanzas.”

Behre Dolbear concluded, “Exploration opportunities to expand the known mineralization down-dip and along strike to the north, south, and east are still good, and excellent in the East Side and Chute zones, and have the potential of adding considerably to the estimated Measured and Indicated Resource.”

The updated resource estimate for the Lucerne Resource Area incorporates these new results, and now totals 53,550,000 tons of Measured and Indicated Resources, containing 1,586,000 ounces of gold and 15,330,000 ounces of silver. The total of 1,880,000 gold-equivalent ounces1 in the Lucerne Resource Area is a 25% increase over the total stated in the September, 2011 Technical Report (the “2011 Report”).

Dayton Area Details

The 2013 Report also re-states the Company’s mineral resource estimate for the Dayton Resource Area, which was completely described in the 2011 Report. This area, south of the Lucerne Resource Area, includes the historic Dayton, Alhambra, Kossuth, Cherokee, and Metropolitan mines.

Ongoing Activities

The Company is currently ramping-up mining and processing activities in the Lucerne mine, with the goal of increasing the production rate to 400 gold-equivalent ounces per week. The ongoing technical program includes continuing infill drilling, metallurgical testing, and geotechnical testing for a second mine in the Dayton Resource Area. In addition, the Company is designing a new phase of exploration drilling to include its highest-potential targets, including fully-developing the East Side and Chute targets in the Lucerne Resource Area, and the continuation of the mineralization from the Dayton Resource Area into both the Spring Valley and Oest target areas.

Mr. DeGasperis concluded, "Discovery of the East-side Chute, similar to certain historic bonanzas was inevitable but no less thrilling for our team. We look forward to finalizing our updated drill programs for 2013, and resuming those activities after the Lucerne Mine stabilizes production at our 400 ounce per week target."


[1] Gold equivalent ounces were calculated using January 31, 2013 London PM prices of $1,664.75 per ounce of gold and $32.03 per ounce of silver, as published by kitco.com. This resulted in a ratio of 51.97 ounces of silver per equivalent ounce of gold, without taking into consideration the relative recoveries of gold and silver. The Company’s current estimates for heap leach recovery are 70% for gold and 45% for silver.
