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.

- 矿产资源估算的生效日期为2023年10月16日。Hard Rock Consulting, LLC.，SME-RM，P.G. Richard A. Schwering先生的估算合格人独立于南山矿业有限责任公司。
- 矿产资源不是矿产储量，没有显示出经济可行性，例如稀释材料和抵消开采或开采材料时可能发生的损失；或修改因素，包括但不限于采矿、加工、冶金、基础设施、经济、营销、法律、环境、社会和政府因素。
- 推断的矿产资源是矿产资源的一部分，其品位或质量是根据有限的地质证据和抽样估算的。推断的矿产资源没有显示出经济可行性，因此不得转化为矿产储量。有理由预计，通过持续勘探，大多数推断矿产资源可以升级为指示矿产资源，但不能保证。
- 据报道，在连贯的线框模型中，矿产资源的地下采矿截止点为97.50美元的熔炼厂净回报率（“NSR”）。NSR的计算和截止值基于以下假设：金价为1,800美元/盎司，银价格为23.50美元/盎司，铅价格为1.00美元/磅，锌价格为1.35美元/磅，铜价格为4.00美元/磅；金的大规模硫化物类冶金回收率和应付账款为52.25％，银为71.25％，锌为71.40％，61.40％ 铅为6.50％，铜为49.00％，熔炼厂总成本为33.29美元；锡卡恩型冶金回收率和应付账款为71.25％，银为80.75％，锌为51.00％，铅为47.50％，铜为87.70％，冶炼厂成本为7.24美元；假设采矿成本为65美元/吨，加工成本为25美元/吨，一般和管理费用为7.50美元/吨。根据规定的价格和回收率，NSR 计算公式如下：NSR =（Ag 等级 * Ag 价格 * Ag 回收和应付账款）+（金级 * Au 价格 * Au 回收和应付款）+（Pb 等级 * 20 * Pb 价格 * Pb 回收和应付款）+（铜等级 * 20 * 锌价格 * 锌回收和应付款）+（铜品位 * 20 * 锌价格 * 锌回收和应付款）+（铜品位 * 20 * 锌价格 * 锌回收和应付款）+（铜品位 * 20 * 锌价格 * 锌回收和应付款）+（铜品位 * 20 * 锌价格 * 锌回收和应付款）冶金领域。锌当量等级计算方法为：锌等级 +（（（铅价格 * 铅回收和应付款）/（锌价格*锌回收和应付款））* 铅等级）+（（（铜价格 * 铜回收和应付款）/（锌价格 * 锌回收和应付款））* 铜品位）+（（（银价 * Ag 回收和应付款））* Ag 等级）+（（（金价格 * 金回收和应付款）/（锌价格 * 20 * 锌回收和应付款））* 金等级）（每个冶金域）。
- 四舍五入在计算吨数、等级和所含金属含量时可能会产生明显的差异。吨位和等级采用美国惯用单位。

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 ).
