Mogotes signs option with Rio Tinto on gold-copper porphyry project in USA

Toronto, Ontario--(Newsfile Corp. - April 15, 2026) - Mogotes Metals Inc. (TSXV: MOG) (FSE: OY4) (OTCQB: MOGMF) (" Mogotes ", or the " Company ") is pleased to announce that the Company has entered into an option-to-joint-venture agreement with Kennecott Exploration Company (a subsidiary of the global mining company Rio Tinto) over a gold and copper discovery in Montana, U.S.A. Large prospective claims package in USA with pre-resource, exploration stage, gold-copper porphyry project discovered by Kennecott/Rio Tinto (RTX) in 2006 within the historic Copper Cliff mining district (Figure 1). Mogotes Metals used RTX drill data base (25 holes totaling 32,000 m), including 7 holes within the porphyry to calculate Au-Cu intercepts (Table 1) with a best intercept to date of Hole 14CC0013, 1252.5 m at 0.41 g/t Au, 0.34% Cu, from 665 m incl** 305.2 m at 0.67 g/t Au, 0.59% Cu, from 859.3 m incl** 79.8 m at 0.51g/t Au, 0.45% Cu from 1246 m  incl** 137.4 m at 0.72g/t Au, 0.51% Cu from 1456 m No exploration of the project since 2017 leaves significant potential to grow the footprint of the known porphyry mineralization with further step-out drilling.

Mogotes Metals used existing drill intercepts to define an exploration target footprint, to guide the next stages of planned drilling, with dimensions of 1000 m vertically and a projected surface area of approx. 450 by 300 m (Figure 2). Copper Cliff exploration season is counter cyclical to the exploration season for Mogotes Filo Sur project providing potential for year-round exploration and news flow for the company. Mogotes will provide further technical information on the Copper Cliff project in the coming days.

We are very excited to enter into this option which contemplates Mogotes earning up to 60% stake in the project, with all consideration for the option being in expenditure on project-related work. This deal leverages our company's platform in the most effective way possible, allowing us to explore for tier-1 large-scale gold-copper porphyry systems all year round as this project will be drilled during the northern hemisphere summer months when the Filo Sur project is in winter conditions." Location and Project Introduction The Copper Cliff Project is located within the US state of Montana in the Garnet Range, 13 km south-east of the town of Potomac, 55 km north-west of Philipsburg Ag-Pb-Zn skarn and 115 km from the large-scale the Butte Cu-Mo (Au-Ag) porphyry historic mining districts 1 (Figure 1).

The Project covers the historic Copper Cliff mining district which operated intermittently from the early 1890's to 1940's with estimated production of 110k lbs of copper 260 oz Au and 570 oz Ag from supergene mineralization 2,3 . During 2006 to 2017 Kennecott / Rio Tinto Exploration discovered a significant body of Au - Cu porphyry mineralization drilling to depth under the district scale advanced argillic (AA) to phyllic "lithocap" alteration system that is host to the historic Cu-Au mineralization 2,3 . The Copper Cliff porphyry and large land package are considered by Mogotes Metals to be significantly underexplored and very attractive for further discovery of Au-Cu mineralization.

(guaranteed by Mogotes Metals Inc.) and Kennecott Exploration Company have entered into an option-to-joint-venture agreement covering the Copper Cliff Project in Granite and Missoula Counties, Montana (patented and unpatented mining claims and fee mineral parcels, subject to existing third-party NSR royalties on certain claims). Under the agreement, Mogotes has the right to earn up to a 60% undivided interest by sole-funding staged exploration expenditures: (i) a minimum commitment of US$4.0 million within the first anniversary of the effective date, and (ii) a further minimum US$12.0 million by the third anniversary to earn a 51% interest (US$16.0 million aggregate, with at least 70% of the US$16.0 million attributable to drilling-related expenditures). After earning 51%, Mogotes may elect to earn an additional 9% (to 60%) by spending a further minimum US$40.0 million by the sixth anniversary (US$56.0 million aggregate).

Following Mogotes' earn-in, the parties would form a joint venture with interests reflecting the earn-in level (49% Kennecott / 51% Mogotes at 51% earn-in; or 40% Kennecott / 60% Mogotes at 60% earn-in), subject to Kennecott's back-in rights: within 90 days after the 51% earn-in, Kennecott may increase its interest by 2% (to 51%/49%) by paying Mogotes US$32.0 million (and the further 60% earn-in option would fall away); and within 90 days after the 60% earn-in, Kennecott may increase its interest by 20% (to 60%/40%) by paying Mogotes US$140.0 million.

The Company is under no obligation, nor does it intend to update or revise the forward-looking information, whether as a result of new information, future events or otherwise. Sampling and Analytical Procedures All Rio Tinto (RTX) drilling through the mineralized intervals of the Copper Cliff porphyry were drilled as PQ, HQ and NQ diamond core, with hole diameters varying depending on depth of hole.

Hole depths ranged from 655 m to 2,019.6 m. Drill core was boxed and transported to the RTX core logging facility in the nearby town of Potomac for logging and sampling. Core recoveries were generally very good, with an average recovery of 93.1% for the reported holes.

Core was logged and sample intervals were selected by RTX geoscientists. Sample intervals were typically 2m in length but ranged from 0.13m to 7m depending on geological boundaries determined by the geologist. Drill core was photographed dry and wet before core was cut in half with a diamond saw blade.

Half core was placed in a sample bag with a unique sample ID for assaying. Samples were dispatched to ALS Laboratories in the USA, which is an accredited analytical laboratory. Samples were dried, crushed and pulverized prior to analysis.

Au was analyzed by a 30 g fire assay with atomic absorption (AA) or ICP-AES finish. Cu, Ag, Mo was analyzed via four acid digestion with ICP-AES or ICP-MS finish, and over detection Cu results were re-analyzed using an ore grade ICP method. RTX assay quality-assurance and quality-control (QAQC) protocols included routine insertion of proprietary certified reference material (CRM), blanks and duplicates.

CRMs were officially certified and certificates were provided to Mogotes by RTX. The combined CRM + blank insertion rate averaged 12.1% for the Copper Cliff project, which is at or above industry standards for exploration stage drilling. Duplicate samples, including field, coarse reject and pulp duplicates, were inserted at a rate of 17.5 %, which is at or above industry standards.

Validation of the RTX supplied drill database was completed by Mogotes. Assays for Au, Cu, Ag, Mo were cross referenced to certified laboratory certificates, with no inconsistencies between the drill hole database and laboratory certificates identified. Mogotes completed a systematic cross-check analysis of RTX CRM performance.

No material issues were identified, confirming accurate and repeatable analytical results within industry accepted standards. Mogotes verification of the Copper Cliff project is on-going at this time. Mogotes has relied on geological information, collar coordinates, azimuth and downhole survey information provided in the RTX drill hole database and geological reports.

Drill hole intercepts reported by Mogotes Metals were defined using 0.3% and 1.0% CuEq cut-off with no metal recovery factor was applied. A maximum internal dilution of 20m, below the stated cut-off grade was allowed. All mineralized intercepts are reported as downhole intervals of Au-Cu-Ag-Mo metal with no metal equivalent grades reported.

Insufficient information is currently available for true width determinations.
