FAIRBANKS, AK -- (November 21, 2024) -- Contango ORE, Inc. (“Contango” or the “Company”) (NYSE American: CTGO) is pleased to announce drill results from the 2024 surface drill campaign and provide an update on its 2024 exploration and development program at the Johnson Tract polymetallic gold project (the Project). The Project hosts the high-grade Johnson Tract deposit (the JT Deposit) with an Indicated Resource of 1.05 million ounces at 9.39 grams per tonne (g/t) gold equivalent (AuEq) with average true thickness of 40 meters (m).

The 2024 exploration program drilled approximately 3,000 m (9,842 feet) in 18 holes drilled to infill the upper one-third of the near vertical resource and three holes drilled for hydrogeological testing and monitoring to characterize the overall hydrology and water quality around the JT Deposit. A number of the holes will also be used for further metallurgical testing and geometallurgical characterization. Contango continued advancing field studies to support permitting and engineering of an exploration drift to access the deeper, high-grade portion of the JT Deposit for infill and exploration drilling.

HIGHLIGHTS OF THE 2024 PROGRAM

  • Receipt of a 404 Permit for construction of a 2.6 mile (4 km) access road from the camp to the proposed portal and laydown site.
  • Twenty-one drillholes yield thick, high-grade intercepts typical of the JT Deposit, with highlights including:
    • GT24-008 - 5 m at 11.5 g/t AuEq (drilled down plunge for hydrogeologic purposes), including
      • 5 m at 30.3 g/t AuEq
    • GT24-007 – 93.0 m at 9.1 g/t AuEq, including
      • 1 m at 20.7 g/t AuEq, and
  • JT24-159 30.2 m at 6.3 g/t AuEq, including
    • 7 m at 10.6 g/t AuEq

See Table 1 for complete list of results.

  • Hydrogeologic and geotechnical testing of three drillholes and installation of additional monitoring wells (MW) and vibrating wire piezometers (VWP).
  • Ongoing field studies related to permitting and engineering for the exploration drift and for a future Feasibility Study.

Rick Van Nieuwenhuyse, President & CEO said: “We are excited to report results from Contango’s first drill program since acquiring the Johnson Tract Project in July. The infill drilling serves as a reminder of the exceptional grade, continuity, and width of the JT Deposit. We are focused on advancing the Project towards feasibility and a mine development decision using our DSO approach. Right now, that means advancing geotechnical, hydrologic, and other environmental and engineering studies in preparation for permitting an approximately 1.6 km (1 mile) exploration tunnel to support definition drilling of the deeper 2/3rds of the JT Deposit.  We are pleased to have received a Section 404 permit from the US Army Corps of Engineers for construction of a portal access road and expanded airstrip. We plan to continue permitting the portal site with the Alaska Department of Natural Resources Office of Project Management and Permitting (OPMP).  Planning is underway for a 2025 program.”

2024 DRILL RESULTS

The results from the 2024 drill program are reported below.  A total of 21 HQ diamond drillholes (including one failed hole) for a total of 3,092.3 m were completed, including three hydrogeologic/geotechnical holes (924.7 m) and 18 shallow infill holes (2,167.6 m). Table 1 lists the drill results for all metals analyzed (gold-silver-copper-lead-zinc, as well as gold equivalent calculations). Please note the formula for calculating gold equivalent. Figures 1 and 2 show a plan map location for the drilling and pierce points for the drill holes on a long section through the mineralized zone.

Infill holes targeted the top third of the deposit from surface at 25 m spacing with the purpose of upgrading the 2022 Mineral Resource Estimate (MRE) to the Measured and Indicated categories. Deeper, higher-grade parts of the deposit are increasingly difficult to intersect at appropriate angles from surface due to topographic constraints and are planned to be drilled from underground following the development of the exploration drift.

Hydrogeologic holes were drilled to add two VWPs and one MW in addition to hydrogeologic packer testing to characterize the hydrology of the Dacite Fault, the JT Deposit, and immediate host rocks west of the Dacite Fault. Work was done in 2023 to characterize the hydrology of the exploration drift development rock west of the Dacite Fault. Hydrogeologic data from 2023 and 2024 will be modeled for planning and permitting of the exploration drift and future mine development.

In addition to standard assays, samples were also selected for specific gravity from the 2024 drillholes to improve density calculations in future mineral resource estimates. Additional sampling was completed for metal leaching and acid rock drainage (ML/ARD) characterization of the mineralized and altered rocks in and around the resource. This ML/ARD work began in 2022 and is ongoing. Work was also begun towards geometallurgical modeling of the JT Deposit.

2024 EXPLORATION AND DEVELOPMENT ACTIVITIES

A 1 mile (1,600 m) exploration tunnel at the JT Deposit is planned to provide a platform for cost-effective, tightly spaced definition drilling of the highest-grade portions of the JT Deposit and support future engineering and mine planning work for a Feasibility Study. The tunnel will also be designed for potential future mine access and haulage, and to support further deep exploration targets.

In support of the exploration tunnel and a future Feasibility Study, Contango completed a comprehensive field program in 2024 consisting of hydrogeological test work, engineering, and numerous environmental and cultural studies, including surface hydrology work, surface and groundwater sampling, fish habitat assessment and biomonitoring, wetlands mapping, nesting raptor surveys, and meteorological data collection. A Clean Water Act Section 404 permit was received on September 10, 2024, from the US Army Corps of Engineers, to construct a 2.6 mile (4 km) portal access road and expanded airstrip.  Planning is underway for a 2025 program.

ABOUT JOHNSON TRACT

The JT Deposit is located two hundred kilometers (125 miles) southwest of Anchorage on private land. The deposit contains an Indicated Resource of 3.49 million tonnes (Mt) grading 9.39 g/t AuEq for 1,053,000 ounces AuEq and an additional Inferred Resource of 0.71 Mt grading 4.76 g/t AuEq for 108,000 ounces AuEq (see Technical Report titled "Updated Mineral Resource Estimate and NI 43-101 Technical Report for the Johnson Tract Project, Alaska" dated August 25, 2022). The JT Deposit remains open along strike and down dip and there are multiple other exploration targets along a 12 km (7.5 mile) mineralized corridor.
