Encouraging results include 3.05 METERS AT 20.83 g/t AuEq within 7.62 meters at 9.51 g/t AuEq.
La Jolla, California, July 13, 2021. TONOGOLD RESOURCES, INC. (OTC TNGL) (“Tonogold” or “the Company”) is pleased to announce the results of recent drilling on the Comstock Lode in the Comstock Mining District near Virginia City, Nevada.
Tonogold aims to prove the existence of a substantial mineable resource of gold and silver in the Comstock Mining District.
COMSTOCK DRILLING
Tonogold has received assays from five recently completed holes in the Company’s ongoing exploration of the Comstock Lode. Drilling has shifted to testing the mid to shallow levels of the Lode where two holes were completed in the Segregated Belcher target (TC-009 and TC-010) and the remaining three holes tested the Con Imperial-Alpha target (TC-011, TC-012, and TC-013). Highlights of the results include 6.10 meters (m) at 6.77 grams per tonne gold equivalent (g/t AuEq) in TC-009, 1.52 m at 5.60 g/t AuEq in TC-011, 7.62 m at 9.51 g/t AuEq in TC-012 including 3.05 m at 20.83 g/t AuEq, and 1.52 m at 4.02 g/t AuEq in TC-013.
Results of the five holes are summarized in the following table:
*AuEq calculated utilizing the following formula: Au g/t + (Ag g/t ÷ 60).
True thickness is estimated at approximately 80% to 95% of interval length for TC-009, 65% for TC-010, and 70% to 75% for TC-011, TC-012 and TC-013.
Brian Metzenheim, interim CEO, commented: “The recent drilling confirms Tonogold’s theory that mineralized material assaying between 5 and 50 g/t AuEq remains in place along the Comstock Lode. We look forward to the results of the additional holes completed in the area and are reviewing permitting options for additional drilling.”
Bad ground conditions at the level of the footwall zone in the Segregated Belcher target resulted in little to no sample recovery in both holes that tested this level (TC-009 and TC-010, see Figure 2 below). As a result of the poor sample recovery, the zone has not been adequately tested. The Company is evaluating other techniques to improve sample recovery before committing to additional drilling in the deeper levels of the Comstock Lode.
Results of the drilling are summarized in the following figures.

Tonogold has completed an additional three holes in the upper levels of the Comstock Lode, one hole in the southern portion of the Con Imperial target and two holes in the Divide area (at the old Bullion Mine). Assays for these holes are pending.
Drilling with the truck mounted RC rig was recently discontinued and the rig has been removed from the property. The current phase of exploration anticipates completing an additional nine holes planned on Potosi and Chollar ground, at the northern end of the company’s land holdings along the Comstock Lode. These holes will be completed utilizing the track rig following completion of drilling on the Occidental/Brunswick Lode. Looking further ahead, the company is utilizing its unique combination of geological and historical analysis to develop additional exploration targets that will advance its goal of defining a substantial mineable resource of gold and silver in the Comstock Mining District.

TONOGOLD’S QA/QC PROCEDURES
Drill core is logged for geology, photographed, and marked for sampling on breaks averaging 1.52 meters in length. Following logging, the core is sawn in half with one half placed in labeled sample bags and sealed for delivery to the assay lab. RC samples are collected on 1.52-meter intervals in labeled sample bags and generally contain a ¼ split. Representative chips from the intervals are logged for geology. Both core and RC samples are stored at a secure facility prior to transport to the assay lab.
Certified standards, blanks, and duplicate samples are inserted in the sample series at the rate of one each per every 20 samples. Samples are delivered to ALS Minerals’ lab in Reno, Nevada where they are dried, crushed, and pulverized. Gold analysis is performed at the Reno facility utilizing a 50-gram fire assay with an AA finish (Au-AA24). Samples containing greater than 10 g/t Au are reanalyzed utilizing fire assay with a gravimetric finish (Au-GRA21). Silver analyses are completed at ALS Minerals’ Lab in Vancouver, Canada using a four-acid digestion with an AAS finish (Ag-AA61). Samples containing greater than 100 g/t Ag are reanalyzed utilizing a four-acid digestion with an ICP-AES finish (Ag-OG62). Results for standards, blanks, and duplicates are monitored for precision, accuracy, and contamination upon receipt of assays.
