VANCOUVER, British Columbia, Nov. 08, 2021 (GLOBE NEWSWIRE) — Millrock Resources Inc. (TSX-V: MRO, OTCQB: MLRKF) (“Millrock” or the “Company”) is pleased to announce it has signed a binding letter agreement (“Letter Agreement”) with Mine Discovery Fund Pty. Ltd. (“MDF”) concerning its El Batamote porphyry copper exploration project in Mexico. MDF is a private Australian company. In good faith, MDF has made an initial US$50,000 cash payment upon signing the Letter Agreement. A definitive agreement (“Definitive Agreement”) has been prepared will be signed immediately following the formation of a Mexico subsidiary company by MDF. MDF has placed Batamote into a wholly-owned subsidiary company called Latin America Copper Limited(“LatCopper”) along with other assets in Chile. MDF indicates it has commenced compliance documentation for a potential ASX or TSX listing in the first half of 2022.

Millrock President and CEO Gregory Beischer commented: “Batamote has excellent potential to discover a porphyry copper deposit. We know already that breccia-style and porphyry copper mineralization is present. We are particularly excited to drill-test beneath what appears to be a leach cap alteration zone at a prospect called El Choclo NW. The project is situated within a belt that has produced very large porphyry copper deposits being mined by others as evidenced by the Cananea and La Caridad mines.”

Latin American Copper Director Joseph Webb commented: “With the addition of El Batamote, LatCopper has three exceptional cornerstone exploration assets with evidence of Tier 1 scale potential in the globally significant copper belts of Latin America. El Batamote is 25 kilometers northwest of Grupo Mexico’s La Caridad copper mine (5.98 billion tonnes at 0.34% copper equivalent) with an untested leach cap identified along strike from known mineralisation. This indicates potential for supergene mineralisation at Choclo. The Bata Sur definitive mineralised porphyry system intersected by historic drilling remains open along strike.

Under the terms of the Definitive Agreement, LatCopper will have the option to purchase a 100% interest in the concessions that underlie the Batamote copper project. To earn the interest, LatCopper will have to make cash payments totalling US$1,000,000 over five years, execute US$6,000,000 dollars in exploration work, and pay Millrock US$250,000 in shares when LatCopper becomes a publicly listed company. In the event that LatCopper exercises the option to purchase the Batamote project, annual advanced minimum royalty (“AMR”) payments will be triggered. The first payment will be US$50,000 and the payment will increase by US$50,000 each year until a cap of US$500,000 is reached. Annual payments will then remain at the capped level until a mine reaches commercial production. At that point, a Net Smelter Return production royalty of 1.0% will be triggered. Any AMR payments made by LatCopper can be credited against production royalty payments.

About the El Batamote Project

The project is located 100 kilometers south of the Sonora – Arizona border and 140 kilometers north of the mining hub of Hermosillo in northeastern Sonora State, Mexico. The project is fully accessible by road and covers nearly 4,000 hectares. Millrock previously purchased the concessions and historical exploration data from a subsidiary of Teck Resources Ltd., as announced by Millrock in a November 2015 press release. The project is situated within the Cananea-La Caridad Copper Porphyry belt (Figure 1). This district-scale structural trend is situated within the larger North American porphyry copper province containing over 20 copper-molybdenum deposits and mines in Arizona, New Mexico, and Sonora.

El Batamote contains alteration and geochemistry characteristics of a Cu-Mo porphyry system. Important historical work has been conducted on the property by large companies such as Phelps Dodge, BHP, Noranda, Peñoles, and Teck. Abundant information was generated by prior workings in the south and central part of the claim block and includes regional and semi-detail mapping, geochemistry, petrography, spectrometry, geophysics and drilling with more than 10,000 meters of diamond core having been drilled.

The exploration led to the discovery of several key prospects: Bata Sur, El Choclo NW and El Choclo West (Figure 2). Review of the historic data has led Millrock geologists to make new exploration observations, conclusions, and recommendations. Preliminary plans include geophysical surveys at El Choclo NW, where a possible leach cap is situated adjacent to known porphyry mineralization. No drilling has been done beneath the alteration zone. At the Bata Sur prospect, breccia pipe style mineralization has been intersected by prior drilling. Drilling is recommended to test for higher grade and to test previously untested geochemical anomalies. Millrock has drilling permits in hand.

The lithology and alteration at Batamote are similar to that found at the La Caridad and Cananea mines. The mining concession covers Late Cretaceous Laramide age intermediate composition volcanic sequences which are intruded by a large, multi-phase batholith with multiple, mineralized porphyry pulses along a northwest-trending structural corridor. Porphyry dikes cut the system and are followed by later, mid-Tertiary post-mineral tuffaceous rocks, all of which are cut by long-lived northeast-trending and north-south fault structures. Intermediate volcanic rocks are the main host to copper mineralization. These rocks contain strong hydrothermal alteration related to porphyry-type systems in a three-kilometer by six-kilometer area that on the west side, is truncated by north-west to north-south trending post-mineral faults. Quaternary gravels cover bedrock west of these faults, but porphyry mineralization may be concealed below as potentially indicated by geophysical surveys at Choclo W.
