Comstock Discovers 90+ Foot Zone Averaging 0.042 opt Gold and 0.404 opt Silver; Progresses Dayton Resource Development Towards NI 43-101 Technical Report

VIRGINIA CITY, Nev., Oct. 16, 2018 (GLOBE NEWSWIRE) -- Comstock Mining Inc. (the “Company”) (NYSE American: LODE) today announced assay results from the recently uncovered, high-grade shear-zone in the Dayton adit. The current Dayton sampling and development work includes extended geological mapping, representative sampling of the high-grade shear-zone and metallurgical testing for processing this mineralized material with clean alternatives to cyanide. These efforts are contributing to the development of an updated resource model and the related technical reporting.



Corrado De Gasperis, Executive Chairman and CEO of the Company, said, “When we discovered the exceptional, precious-metal grades in the newly exposed zone (assaying 0.25 opt gold and 3.5 opt silver), we commissioned this sampling plan that has now yielded more than 90 feet of outstanding, continuous gold and silver grades.”

The Company completed an expanded, systematic sampling program that exposed a 90.8 foot (27.7m) mineralized shear zone, starting 245 feet (74.7m) inside the Dayton adit. The expanded program included the collection of continuous channel samples along consistent intervals of the right rib of the adit. Visual geological changes in mineralogy and rock type determined the sample boundaries, with intervals averaging approximately three feet in length.

All samples were fire-assayed for detection of gold and silver, and then further analyzed using Inductively Coupled Plasma – Atomic Emission Spectroscopy (ICP-AES) for detection of up to 23 additional elements. The results for the entire 90.8 foot (27.7m) zone averaged 0.043 opt gold (1.47g/t) and 0.404 opt silver (13.8g/t). The zone included 7.5 feet averaging 0.121 opt gold (4.14g/t) and 0.753 opt silver (25.8g/t). The previous identification of elevated values for Molybdenum, Cadmium, Selenium, and Tungsten were confirmed by this latest, detailed sampling.

The development of the Dayton Resource also includes an ongoing evaluation of clean processing alternatives, and extensive metallurgical testing conducted by Itronics, Inc. (OTC:ITRO) using their proprietary KAM-Thio solution. The previous tests by Itronics recovered the substantial majority of the silver while the new KAM-Thio residual solution was substantially regenerating during the metal recovery process, thus reducing the net consumption of the reagents and creating a potentially compelling economic solution. Itronics has also previously reported that the remaining cyanide in the leached material was neutralized by the new leaching process, reducing the cyanide to an almost undetectable level on the spent material.

Mr. De Gasperis added, “We have already reported positive silver results using this solution on previously leached material. We are now extending the tests onto higher-grade, virgin, mineralized materials from the Dayton to determine if we can replicate the clean extraction with gold.”

The Company delivered new samples of higher-grade mineralized material to Itronics for testing, with two objectives: first, to model the same process flow sheet that they developed for processing the Company’s previously leached material, and second, to test the ability of the KAM-Thio liquid to recover gold as well as silver. A battery of tests has been run, based on a hypothetical flowsheet, and solid and liquid samples have been submitted to metallurgical laboratories for analysis.

Dr. John Whitney of Itronics commented, “This is the first time this type of test has been run using KAM-Thio liquid to evaluate the gold solubilization from virgin gold bearing material. If results are positive, then a series of tests will be scheduled to optimize the process.”

Mr. De Gasperis concluded, “A breakthrough with higher, cleaner recoveries, coupled with reduced waste and the recently extended higher precious metal grades at the Dayton, positions us for an updated resource estimate and more importantly, the preliminary economic assessment (PEA) of those gold and silver resources. With these expanded results and scope, we plan on publishing a stand-alone NI 43-101 technical report for the Dayton project during the first quarter of 2019.”

About Comstock Mining Inc.

Comstock Mining Inc. is a Nevada-based, gold and silver mining company with extensive, contiguous property in the Comstock District and is an emerging leader in sustainable, responsible mining. The Company began acquiring properties in the Comstock District in 2003. Since then, the Company has consolidated a significant portion of the Comstock District, amassed the single largest known repository of historical and current geological data on the Comstock region, secured permits, built an infrastructure and completed its first phase of production. The Company continues evaluating and acquiring properties inside and outside the district expanding its footprint and exploring all of our existing and prospective opportunities for further exploration, development and mining. The near-term goal of our business plan is to maximize intrinsic stockholder value realized, per share, by continuing to acquire mineralized and potentially mineralized properties, exploring, developing and validating qualified resources and reserves (proven and probable) that enable the commercial development of our operations through extended, long-lived mine plans and developments that are economically feasible and socially responsible.
