Comstock Mining Announces Best Intercepts and Widths To-Date

VIRGINIA CITY, NV - Comstock Mining Inc. reported some of the highest grade and thickest gold and silver core intercepts, to date, from the higher-grade mineralization hosted in the Quartz Porphyry mass (PQ Target). These results represent the completion of the first phase of underground exploration and illustrate an increase in mineralization thickness, grade quality, and continuity as exploration has continued north in this highly mineralized corridor.

These intercepts are currently being modeled to provide grade shells that will contribute to an underground mine plan for the broader Lucerne mineralized resource.

Corrado De Gasperis, President & CEO, said, "Initially, drilling from bays 1 & 2 of the PQ Target produced exceptional grades mainly defined by thin widths but as we continue to drill north of the Succor vein, we have continuously identified higher-grade intercepts of thicker widths, consistent with our expectations and strongly supporting continued northerly exploration. We have defined a second phase of efficient drilling, enabled by our new underground drifts, extending north for evaluation of the PQ and Woodville targets and east for the Succor target."

In September 2015, the Company began construction of the Harris Portal and Drift on the floor of the Lucerne Mine with two objectives. First, the Harris Drift provides a central platform within Lucerne's broader geological corridor to conduct an underground drilling and exploration program, targeting a three quarter mile long mineralized corridor that includes the PQ target, Woodville, Succor/Holman and high-grade Chute zone systems. Second, the Harris Drift could also potentially serve as a central haulage level depending on the overall drill results and resultant mine plans.

The initial phase included approximately 12,400 feet of diamond core drilling that is in the form of 'fans' that comprise a group of holes having different dips (between -50 and +40 degrees from horizontal). Each drill bay has two or three fans of drill holes extending into the primary target. The core locations and orientations were specifically designed to infill and expand the areas of known, higher-grade mineralization identified from previous surface drilling programs.

The core holes from the first four drill bays were designed to evaluate the southern lobes of the quartz porphyry, and the extent of the fractured and veined environment lying beyond and to the south. The initial drill bays also included a group of holes that targeted and penetrated the Succor structural intersection. In general, the initial southerly oriented drill holes intersected more narrow (2 to 10 feet thick) zones of higher-grade mineralization. The subsequent intercepts continue to illustrate an increase in mineralization thickness, grade quality, and continuity as exploration continues north in this highly mineralized corridor. The intercepts also tend to lie along the margins of a second, previously un-described intrusive mass of material that is proving more consistent higher-grade results.

"These intercepts reflect the higher grade epithermal mineralization the Comstock is known for and, not coincidently are being targeted by us in the historic Succor and Woodville systems. Historical production grades from the Succor and Woodville mines averaged over 0.650 and 0.900 opt Au, respectively, said De Gasperis."
