Boise, Idaho--(Newsfile Corp. - December 21, 2023) - Thunder Mountain Gold, Inc. (OTCQB: THMG) (TSXV: THM) (the "Company" or "THMG") is pleased to report a newly filed NI 43-101 Mineral Resource Estimate ("43-101 43-101 MRE") incorporating results from surface diamond drilling program conducting in 2021 at the South Mountain Project ("South Mountain" or "South Mountain Project" or the "Property") in southwestern Idaho, U.S.A. The updated 43-101 MRE includes an increased resource for the Project while maintaining the high-grade mineralization.
The updated Independent 43-101 MRE, which has an effective date of October 16, 2023, was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI-43-101") by Hard Rock Consulting, LLC, based in the U.S.A. More details are included in Table 1 below.
HIGHLIGHTS OF UPDATED MINERAL RESOURCE
Measured & Indicated ("M&I"): 223,000 tons grading 9.02% Zinc ("Zn"), 4.27 ounces per ton ("opt") Silver ("Ag"), 0.059 opt Gold ("Au"), 0.64% Copper ("Cu"), and 0.94% Lead ("Pb").
This represents a 7.7% increase to the M&I tonnage from the previous 2021 43-101 MRE, with a 18.82% Zn equivalent grade ("ZnEq"), or a 20.55opt Ag equivalent grade ("AgEq")
Inferred: 959,000 tons grading 7.56% Zn (14% increase in Zn lbs), 5.67 opt Ag (14.10% increase in Ag ounces), 0.037 opt Au (3.3% increase in Au ounces), 0.80% Cu (14.5% increase in Cu lbs), and 1.06% Pb (25.4% increase in Pb lbs).
This represents a 15.1% increase in the Inferred tonnage from the previous 2021 43-101 MRE with an 17.2% ZnEq or a 19.30 opt AgEq.
The DMEA Zone in the model was extended an additional 250 feet down dip and remains open.
"We are extremely pleased by the results of the revised 43-101 MRE. These deep surface core holes placed to determine the continued downdip potential of the mineralization displayed positive results on our resource. Our independent engineering firm - Hard Rock Consulting, LLC - did a great job with the data. This new data supports previously reported model and results confirming the continuation of all mineralized zones extending down-plunge, and that they continue to remain open at depth," commented Eric T. Jones, President and CEO of Thunder Mountain Gold Inc. "It is still our opinion that South Mountain has the potential to be one of the lowest cost producers of zinc, silver, and gold in north America."
MINERAL RESOURCE ESTIMATE
This latest round of drilling completed during the late fall of 2021 proves the continuation of the down plunge extension of the DMEA zone at depth. This zone remains open in both directions. All the of the drill results have now been in incorporated into the updated 43-101 MRE for the South Mountain deposit. The increase in Measured and Indicated tons are the result of updated metal prices and mining costs. Surface drilling completed in 2021 accounts for approximately 8% of the increase in Inferred tons, while the remaining 7% increase is due to updated metal prices and mining costs.
Table 1 below provides the Mineral Resource Statement for the Project in U.S. units with details of the modelling methodology and cut-off grades applied to the mineral resource. Figure 1 illustrates the principal areas where the South Mountain deposit has been expanded from the historical 43-101 MRE that was completed in 2021. The historical Technical Report for the Mineral Resource Estimate for the South Mountain Project Owyhee County, Idaho USA Report Date: June 15, 2021 - is filed on SEDAR.

- The effective date of the mineral resource estimate is October 16, 2023. The QP for the estimate Mr. Richard A. Schwering, SME-RM, P.G., of Hard Rock Consulting, LLC. is independent of South Mountain Mining, LLC.
- Mineral resources are not mineral reserves and do not have demonstrated economic viability such as diluting materials and allowances for losses that may occur when material is mined or extracted; or modifying factors including but not restricted to mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.
- Inferred mineral resources are part of a mineral resource for which the grade or quality are estimated on the basis of limited geological evidence and sampling. Inferred mineral resources do not have demonstrated economic viability and may not be converted to mineral reserves. It is reasonably expected, though not guaranteed, that the majority of Inferred mineral resources could be upgraded to Indicated mineral resources with continued exploration.
- The mineral resource is reported at an underground mining cut-off of $97.50 U.S. Net Smelter Return ("NSR") within coherent wireframe models. The NSR calculation and cut-off is based on the following assumptions: an Au price of $1,800/oz, a Ag price of $23.50/oz, a Pb price of $1.00/lb., a Zn price of $1.35/lb. and a Cu price of $4.00/lb.; Massive Sulfide type metallurgical recoveries and payables of 52.25% for Au, 71.25% for Ag, 71.40% for Zn, 66.50% for Pb, and 49.00% for Cu and a total smelter cost of $33.29; Skarn type metallurgical recoveries and payables of 71.25% for Au, 80.75% for Ag, 51.00% for Zn, 47.50% for Pb, and 87.70% for Cu and a smelter cost of $7.24; assumed mining cost of $65/ton, process costs of $25/ton, general and administrative costs of $7.50/ton. Based on the stated prices and recoveries the NSR formula is calculated as follows; NSR = (Ag grade * Ag price * Ag Recovery and Payable) + (Au grade * Au price * Au Recovery and Payable) + (Pb grade * 20 * Pb Price * Pb Recovery and Payable) + (Cu grade * 20 * Cu Price * Cu Recovery and Payable) + (Zn grade * 20 * Zn Price * Zn Recovery and Payable) for each metallurgical domain. The zinc equivalent grades were calculated as Zn Grade + (((Pb Price * Pb Recovery and Payable) / (Zn Price*Zn Recovery and Payable)) * Pb Grade) + (((Cu Price * Cu Recovery and Payable) / (Zn Price * Zn Recovery and Payable)) * Cu Grade) + (((Ag Price * Ag Recovery and Payable) / (Zn Price * 20 * Zn Recovery and Payable)) * Ag Grade) + (((Au Price * Au Recovery and Payable) / (Zn Price * 20 * Zn Recovery and Payable)) * Au Grade) for each metallurgical domain.
- Rounding may result in apparent differences when summing tons, grade and contained metal content. Tonnage and grade are in U.S. Customary units.

- The effective date of the mineral resource estimate is October 16, 2023. The QP for the estimate Mr. Richard A. Schwering, SME-RM, P.G., of Hard Rock Consulting, LLC. is independent of South Mountain Mining, LLC.
- Mineral resources are not mineral reserves and do not have demonstrated economic viability such as diluting materials and allowances for losses that may occur when material is mined or extracted; or modifying factors including but not restricted to mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.
- Inferred mineral resources are part of a mineral resource for which the grade or quality are estimated on the basis of limited geological evidence and sampling. Inferred mineral resources do not have demonstrated economic viability and may not be converted to mineral reserves. It is reasonably expected, though not guaranteed, that the majority of Inferred mineral resources could be upgraded to Indicated mineral resources with continued exploration.
- The mineral resource is reported at an underground mining cut-off of $97.50 U.S. Net Smelter Return ("NSR") within coherent wireframe models. The NSR calculation and cut-off is based on the following assumptions: an Au price of $1,800/oz, a Ag price of $23.50/oz, a Pb price of $1.00/lb., a Zn price of $1.35/lb. and a Cu price of $4.00/lb.; Massive Sulfide type metallurgical recoveries and payables of 52.25% for Au, 71.25% for Ag, 71.40% for Zn, 66.50% for Pb, and 49.00% for Cu and a total smelter cost of $33.29; Skarn type metallurgical recoveries and payables of 71.25% for Au, 80.75% for Ag, 51.00% for Zn, 47.50% for Pb, and 87.70% for Cu and a smelter cost of $7.24; assumed mining cost of $65/ton, process costs of $25/ton, general and administrative costs of $7.50/ton. Based on the stated prices and recoveries the NSR formula is calculated as follows; NSR = (Ag grade * Ag price * Ag Recovery and Payable) + (Au grade * Au price * Au Recovery and Payable) + (Pb grade * 20 * Pb Price * Pb Recovery and Payable) + (Cu grade * 20 * Cu Price * Cu Recovery and Payable) + (Zn grade * 20 * Zn Price * Zn Recovery and Payable) for each metallurgical domain. The zinc equivalent grades were calculated as Zn Grade + (((Pb Price * Pb Recovery and Payable) / (Zn Price*Zn Recovery and Payable)) * Pb Grade) + (((Cu Price * Cu Recovery and Payable) / (Zn Price * Zn Recovery and Payable)) * Cu Grade) + (((Ag Price * Ag Recovery and Payable) / (Zn Price * 20 * Zn Recovery and Payable)) * Ag Grade) + (((Au Price * Au Recovery and Payable) / (Zn Price * 20 * Zn Recovery and Payable)) * Au Grade) for each metallurgical domain.
- Rounding may result in apparent differences when summing tons, grade and contained metal content. Tonnage and grade are in U.S. Customary units.

The South Mountain Project
The South Mountain Mine is a polymetallic development project containing high-grade zinc, silver, gold, and copper, and is located approximately 70 miles southwest of Boise, Idaho (See Figure 2). The Project was intermittently mined from the late 1800s to the late 1960s and its existing underground workings remain intact and well maintained. Thunder Mountain Gold Inc. purchased and advanced the project from 2007 through 2022, with expenditures into the project of approximately US$20 million. Historic production at the Project has largely come from high-grade massive sulfide bodies that remain open at depth and along strike. According to historical smelter records, approximately 53,642 tons of mineralized material has been mined to date. These records also indicate average grades; 14.5% Zn, 10.6 o.p.t. Ag (363.42 g/t Ag), 0.058 o.p.t. Au (1.98 g/t Au), 1.4% Cu, and 2.4% Pb were realized (See NI 43-101 Technical Report: Updated Mineral Resource Estimate for the South Mountain Project, dated December 15, 2023, Section 6.4 - Table 6-3 for more details. Available on the Thunder Mountain Gold Inc. website and at ).
南山礦是一個含有高品位鋅、銀、金和銅的多金屬開發項目，位於愛達荷州博伊西西西南約70英里處（見圖 2）。從1800年代末到1960年代後期，該項目斷斷續續地開採，其現有的地下作業完好無損，維護良好。Thunder Mountain Gold Inc. 在2007年至2022年期間收購併推進了該項目，該項目的支出約爲2000萬美元。該項目的歷史產量主要來自於高品位的塊狀硫化物體，這些物體在深度和走向過程中都保持開放狀態。根據冶煉廠的歷史記錄，迄今爲止已經開採了大約53,642噸礦化材料。這些記錄還顯示平均成績； 14.5% 鋅，10.6 o.p.t. Ag（363.42 g/t Ag），0.058 o.p.t. Au （1.98 g/t Au）、1.4% 的銅和 2.4% 的鉛 被實現了 （更多細節見2023年12月15日的NI 43-101技術報告：南山項目的最新礦產資源估算，第6.4節——表6-3。可在雷山黃金公司網站上找到，網址爲）。
