Contango Announces S-K 1300 Technical Report Summary with

Robust Economics and One Year Payback for its Johnson Tract Project

FAIRBANKS, AK — (May 6, 2025) — Contango ORE, Inc. (“Contango” or the “Company”) (NYSE American: CTGO) is pleased to announce that it has completed the Technical Report Summary (“TRS”) on the Johnson Tract Project (the “Project” or “Johnson Tract”), located in Alaska, U.S.A. The TRS summarizes the results of an Initial Assessment (“IA”) of the potential viability for a seven-year life of mine (“LOM”), underground mining operation, utilizing the same direct ship ore (“DSO”) approach as the highly successful Manh Choh mine.

Rick Van Nieuwenhuyse, the Company’s President and Chief Executive Officer said: “We are very pleased to release the results of our Initial Assessment for our Johnson Tract Project. Assuming a price of $2,200 per ounce of gold as the “Base Case”, the Project generates a Post-Tax NPV5 of $225 million and IRR of 30% with a one-year payback from commencement of commercial production. Assuming a price of $3,000 per ounce of gold price demonstrates an NPV5 of approximately $400 million and IRR of 45% with less than a year payback from commencement of production. Initial capital costs are estimated at a modest $214 million with an all-in-sustaining cost (“AISC”)1 of $860 per gold equivalent ounce (“GEO”) sold at an average GEO ore grade estimated at 7.58 grams per tonne (“g/t”). Based on current resources, it is estimated that Johnson Tract will produce an annual average of 102,258 GEO and that 90,692 GEO will be recovered after processing and refining over the seven-year operating life (following the Initial Capital/Pre-Production phase). Once we get underground, we believe that drilling will define additional resources that will extend the current LOM.

We look forward to investigating potential upsides to improve the economics and extend the mine life, which includes additional underground drilling to expand the resource to extend the known orebody down dip and along strike. Another upside that we plan to evaluate is the use of ore sorting to upgrade run of mine ore grades at site by using sensor-based sorters (for example:

 

1 AISC includes all direct and indirect operating cash costs related directly to the physical activities of producing gold, copper, zinc, lead and silver including mining, processing and other plant costs, third-party refining expense, on-site general and administrative costs, sustaining capital and reclamation costs. Excluded from AISC are initial capital costs in the amount of $213.6 million (pre-production costs), as well as royalty and mining production taxes.


Optical, XRT, Laser, X-Ray) to separate waste material from higher grade ore. This would result in two improvements - fewer tonnes to transport and higher head grade feed to the mill, resulting in improved economics.

We are currently focused on permitting the underground tunnel to access the million-ounce resource and conduct a detailed underground in-fill drill program. We will also conduct metallurgical, geotechnical and hydrology studies necessary to complete a feasibility study, which will include a detailed mining and transportation plan, as well as select a specific site for processing the ore along with any modifications necessary. In addition, we will need to conduct detailed environmental baseline work along the Road and Port Easements that have already been granted to Cook Inlet Regional Inc. (“CIRI”) by the Federal government earlier this year. We expect the permitting for the proposed tunnel and adjacent laydown site with the State of Alaska will take one year.

Part of Contango’s management team just spent a week in Washington D.C. for the “Alaska on the Hill” event. We began the week meeting with CIRI, our Alaska Native Corporation partner. We had great meetings with the heads of various federal agencies that will be involved with permitting the CIRI Road and Port Easements, along with constructive meetings with our two Senators, Murkowski and Sullivan, and our Congressman, Nick Begich. We were very impressed with the overwhelming support for permitting projects in Alaska, along with the recognition of the importance of developing a domestic source of critical metals. It was noted in such meetings that the Johnson Tract project is the only critical metals mining project in Alaska that is ready for permitting and may be selected when appropriate for FAST-41 priority permitting under the newly created National Energy Dominance Council (“NEDC”) and Permitting Council under the direction of the President’s Executive Order, “Immediate Measures to Increase American Mineral Production”, issued on March 20, 2025. We look forward to working with the Trump Administration and our Congressional delegation to develop the Johnson Tract project and help secure American supply chain of four critical metals.”

BACKGROUND:

 

   

As a U.S. domestic and domiciled company, Contango is required to report its mineral resources in accordance with Subpart 1300 of Regulation S-K (“S-K 1300”).


   

S-K 1300 was adopted by the Securities and Exchange Commission (the “SEC”) to modernize mineral property disclosure requirements for mining registrants and to align U.S. disclosure requirements for mineral properties with current industry and global regulatory standards.

 

   

The mineral resource estimate set forth in this TRS for the Johnson Tract Project has not previously been reported under the S-K 1300 format. The TRS was prepared in accordance with S-K 1300 and will be filed on or before May 12, 2025 with the SEC through EDGAR on Form 8-K.

IA SUMMARY

The IA is preliminary in nature and includes Indicated and Inferred resources that are considered too speculative to apply the economic considerations that would enable them to be categorized as mineral reserves. There is no certainty the estimates presented in the IA will be realized. This economic analysis is based on a Resource Estimate for the deposit listed in Table 3.

Forward-looking statements are based on current expectations, estimates and projections that involve a number of risks and uncertainties, which could cause actual results to differ materially from those reflected in the statements. These risks include, but are not limited to: the risks of the exploration and the mining industry (for example, operational risks in exploring for and developing mineral reserves; risks and uncertainties involving geology; the speculative nature of the mining industry; the uncertainty of estimates and projections relating to future production, costs and expenses; the volatility of natural resources prices, including prices of gold and associated minerals; the


existence and extent of commercially exploitable minerals in properties acquired by Contango or the Peak Gold JV; ability to realize the anticipated benefits of the Peak Gold JV; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; the interpretation of exploration results and the estimation of mineral resources; the loss of key employees or consultants; health, safety and environmental risks and risks related to weather and other natural disasters); uncertainties as to the availability and cost of financing; Contango’s inability to retain or maintain its relative ownership interest in the Peak Gold JV; inability to realize expected value from acquisitions; inability of our management team to execute its plans to meet its goals; the extent of disruptions caused by an outbreak of disease, such as the COVID-19 pandemic; and the possibility that government policies may change, political developments may occur or governmental approvals may be delayed or withheld, including as a result of presidential and congressional elections in the U.S. or the inability to obtain mining permits. Additional information on these and other factors which could affect Contango’s exploration program or financial results are included in Contango’s other reports on file with the U.S. Securities and Exchange Commission. Investors are cautioned that any forward-looking statements are not guarantees of future performance and actual results or developments may differ materially from the projections in the forward-looking statements.
