Contango ORE Issues Initial S-K 1300 Resource Technical Report Summary for the Lucky Shot Project, Alaska - Indicated grades average 15 g/t

Contango ORE, Inc. (“Contango,” “CORE” or the “Company”) (NYSE American: CTGO) announced that it has filed an initial Technical Report Summary (“TRS”) detailing the gold resources at the Lucky Shot Project located near Willow, Alaska. The mineral resource estimates held by Contango at the Lucky Shot Project, effective as of May 26, 2023 comprise Indicated mineral resource estimates of 226,963 tonnes grading 14.5 g/t Au for 105,620 oz Au and Inferred mineral resource estimates of 82,058 tonnes grading 9.5 g/t Au for 25,110 oz Au (see Tables 1 to 3). Estimation sensitivities were run at various capping levels as a check of the appropriateness of loss in total metal content for gold at incrementally lower and higher capping levels. An uncapped gold estimate within the resource shapes produces roughly 30 to 38% more total gold metal globally for both the Lucky Shot and Coleman segments of the Lucky Shot vein (Table 4). The capping level used might have resulted in a higher metal loss than normal (~10%), but this conservative approach was taken due to the extreme grades in some areas and the need to restrict them spatially. In the interest of caution at this stage of the project, the decision was made to use a conservative capping strategy in the current estimation process. With more data, a different approach may be taken. Figure 1 shows the gold composites vs gold estimation for the Coleman segment which has far more drilling than the Lucky Shot segment. The image shows a clear ore shoot geometry that can be used to guide future drilling. The deposits remain open with excellent exploration potential beyond the current mineral resources. As the area in general is underexplored, there is good potential to delineate additional exploration targets on the Lucky Shot Project lease.

Rick Van Nieuwenhuyse, President, and CEO said: “We are indeed excited to report an initial resource at the Lucky Shot Project. What is most important for investors to understand is that when proper drill spacing is achieved, the average indicated grade of the deposit is over 15g/t or nearly half an ounce per ton. Our QP believes that further infill drilling will be able to convert indicated to measured resources and inferred to indicated resources. The current drill spacing, on the Lucky Shot segment in particular, is not dense enough to result in a substantial amount of indicated resources, but future drilling is planned to convert much of the reported inferred to indicated resources in 2023. Now that we have completed access to the downdip projection of the Lucky Shot vein exploration area via the expanded Enserch Tunnel, we will be able to accomplish more detailed infill drilling to define better quality resources. At the Coleman segment, where the drill density is much higher (146 holes versus only 35 at Lucky Shot – see Figures 2 through 5), the QP was unable to justify a measured category (though supported by variography) because Contango did not drill these holes. Our QP recommended a few infill holes to confirm previously drilled areas of the Coleman segment of the vein. One other area of upside refers to the amount of coarse free gold and capping strategy. The current conservative capping strategy reduces global gold content by over 30% compared to uncapped grades (see Table 4). More drilling - particularly in the areas of the higher-grade ore shoots evident in the grade-thickness model (see Figure 1), and bulk sampling of the vein material will assist in a better understanding of grade definition – including a renewed look at the capping strategy. We are very pleased with this initial resource at Lucky Shot and are planning a follow-up surface and underground drill program to augment resources sufficient to begin mine planning.”

ABOUT THE LUCKY SHOT VEIN

The Lucky Shot vein is hosted within a shear zone in medium to coarse grained granodiorite intrusive rock. The granodiorite country rock is normally very competent and stands well underground. The shear zone ranges from 1 to 5 meters (3 to 15 feet) thick and hosts one or more brecciated and sheared quartz veins containing sulfides and fine free gold. Individual quartz veins can be 30 cm (1ft) to over 3 meters thick with associated silicified and stockwork mineralized zones. The Lucky Shot vein is offset along northwest striking and northeast dipping faults that sub-divide the vein structure into segments referred to in the TRS as the Lucky Shot segment and the Coleman segment. The Company completed a total of 3,816 meters (12,519 feet) of underground drilling in 29 HQ drill holes from the Enserch tunnel (see Figures 2, 4, 5 and 6, and Table 5 for location and results). The quartz vein and associated silicified shear zone have elevated very fine grained dark grey sulfides (sulfosalt and telluride mineral species) and medium to coarse grained pyrite. Detailed mineralogic studies are underway. Samples have been taken from vein material as well the immediate footwall and hanging wall of the vein structure.

Gold was discovered in the Lucky Shot area in 1918, with subsequent mining from 1922 to 1942. The Willow Creek mining district historically produced 19 metric tonnes or approximately 610,874 troy ounces of gold from ore ranging between 30 and 60g/t making it the third largest historic lode gold producing district in Alaska (Harlan, et al., 2017). The Lucky Shot mine itself produced a reported 252,000 oz from 169,000 tons of free-milling ore indicating an average head grade of 40 g/t (1.6 oz/tonne) (Stoll, 1997), with additional minor production from the Coleman and War Baby mines. The Company has not undertaken any independent work to verify or confirm the previously reported information (Harlan, et al., 2017 and Stoll, 1997). The historical information may not be representative of future results of the Company’s activities.

ABOUT THE S-K 1300 TECHNICAL REPORT

The TRS on the Lucky Shot Project as of May 26, 2023 was prepared by Sims Resources LLC ("SR"). John Sims, C.P.G., with SR, is the qualified person ("QP") who authored the TRS in accordance with Item 1302 of subpart 1300 of Regulation S-K (“S-K 1300”). The TRS was prepared in compliance with Item 601(b)(96) of Regulation S-K and S-K 1300 and mineral resource estimates have been classified in accordance with the definitions for mineral resources in S-K 1300. The mineral resource estimates were developed using a computer-based block model based on drill hole assay information available through February 2023 and geologic interpretation of the mineralization boundaries. Mineral resources were estimated using the block model and underground shapes created in Leapfrog software at a 3.0 g/t Au cutoff grade to establish the areas of the deposit with reasonable prospects for economic extraction. The mineral resources are contained within two deposits: Lucky Shot and Coleman. The Lucky Shot and Coleman mineralization was modeled incorporating structural offsets and is tabulated in the resource tables of the TRS.
