BRASILES DRILLING TESTS THE NORTHWARD EXTENSATION OF SANTO TOMAS NORTH ZONE – Updated, Canadian Business Journal

Vancouver, Canada, June 23, 2022 (GLOBE NEWSWIRE) — Oroco Resource Corp. (TSX-V: OCO, OTC: ORRCF) (“Oroco” or “Company”) Announces the results of the first exploration drilling in the Brazil zone of the Santo Thomas property (“property“) Northwestern Mexico. Six diamond drill holes have been completed, five of which have been obtained. A surface geological map creation program is also underway. SRK Consultants (Canada) Inc. And the company geologist.

The Brazil Zone is the location of the most extensive area of ​​modified Laramie era invasion into the property.Simultaneous zone of surface mapping and low resistivity Diaz Geophysics A 3D-guided polarization survey (2021) shows a total of 3.5 km of Laramie monzonite dikes and resource extensions north of the northern zone.

The first round of diamond drilling took place in two regions of the Brazil zone.The Brazil main zone It is a famous Gossan on the north bank of the Fuerte River. Exall Resources Limited’s historical records cite three drill hole colors in the area, but do not include records of drilling results. The field program could not find evidence of drill color at the reported location. In addition, two drill holes (B001 and B002) were colored to test the historic area. The excavation resulted in the invasion of limestone, strongly altered pyrite andesite volcanic rocks, and monzonite rocks. The mineralization of important bases and precious metals did not intersect.

Craig Darjeel, Executive Chairman of Oroko, said:

The Western Brazil Zone It is located at the western end of the Brazilian main zone. This is the NNE trend zone on the surface, partially hidden under the veneers of the post-mineralized Sierra Madre Occidental Formation conglomerate. The company tested Brasiles West using diamond drill holes B003 through B006. Assay results are available for all holes except B006.

Most importantly, the Western Brazil Zone has a strong geological similarity to the Northern Zone, even if it is somewhat attenuated. Similar to the North Zone, the monzonite dikes that cut Cretaceous limestone (marble) are associated with skarn development and small amounts of base metal mineralization. Under the limestone, excavation encountered severely crushed and altered andesite and monzonite porphyry dikes, accompanied by chalcopyrite and pyrite, in the same manner as in the North Zone.

Currently, the major Santo Tomas structural zones are recorded on the surface geological map of the Brasiles West Zone, 3.5 km north of the North Zone. Drill holes B003, B004, and B005 show that the first 1.0 km of their extension shows a similar mineralization effect as the North Zone.

The recently completed drill hole B006 is in the untested gap between B005 and the North Zone. Assay results are pending. The Brasiles rig is currently located in drill hole B007, 400m north of B003 / B004, and will be tested for the north extension of the Brasiles West Zone, which merges with the Brasiles Main Zone.

Technical information and quality control and quality assurance

Past drilling data adopted in this current exploration program was subject to the data validation procedures cited in the current technical report. The current program has performed additional drill color validation and the color position is closely aligned with the 2021/2022 survey control. Appropriate QA / QC protocols managed geological logging, core sampling, sample preparation, analysis, and security in the current program. This includes quality control with duplicates, standards, and blanks. The sample was submitted to the Mexican division of ALS Limited in Hermosillo, Mexico, for sample preparation on pulp. The sample pulp is then sent to ALS Canada Ltd. in Vancouver, Canada for analysis. The total content of copper and molybdenum is determined by the tetraacid decomposition of the AAS finish. Gold was determined by fire analysis of 50 grams of charge or for 30 grams of charge (1 assay ton).

About OROCO:

We own a net 73.2% interest in a total of 1,172.9 hectares of core concession for the Santo Thomas project in northwestern Mexico, with a project investment of up to C $ 30 million to increase the majority interest to up to 85.5%. There is a possibility to increase. We also hold a 77.5% stake in the 8,154.3 hectares of mineral concessions around and adjacent to the core concessions (total project area of ​​23,048 acres). This project is located in the Santo Thomas district, about 14 km northeast of Santo Thomas to the Jinchuan Group’s Buff Erati Project. Santo Tomas hosts important copper porphyry deposits defined by prior exploration over the period 1968-1994. Meanwhile, the property has been tested with over 100 diamonds and a reverse circulation drill hole, totaling about 30,000 meters. Based on the data generated by these drill programs, Bateman Engineering Inc. completed a historic feasibility study in 1994.

The Santo Thomas Project is located within 160 km of Topolo Bumpo’s Pacific Deep Sea Port and operates from the city of Los Mochis to the northern city of Choix via the highway and the proximal railroad (and the parallel corridor of the main transmission line and natural gas). It has been. .. The property has a 32km access road built to serve the El Sausal mine in Goldcorp in Chiwawa.
