Oceanus Resources Corporation (TSXV:OCN) (OTCQB:OCNSF) reports it has received assay results of channel samples collected in September, 2019 from legacy underground exploration tunnels and from surface samples on the Caleigh, Canon Combination (unmined portion of the El Tigre vein), Protectora and Aguila veins located north of the old El Tigre Mine in Sonora, Mexico (see Figure 1 sample Location Map).
In the Caleigh vein, approximately 2 kilometers north of the old El Tigre Mine, underground channel sample ETU-1007 returned 2,375.97 g/t silver equivalent consisting of 1,896.3 g/t silver and 6.40 g/t gold over a true width of 0.50 meters. Underground Channel Sample ETU-1006 returned 2,318.35 g/t silver equivalent consisting of 1,970.7 g/t silver and 4.64 g/t gold over a true width of 0.50 meters.
In the Canon Combination vein (unmined portion of the El Tigre vein) underground channel sample ETU-1012 returned 1,812.72 g/t silver equivalent consisting of 1,793.7 g/t silver and 0.25 g/t gold across a true width of 0.50 meters.
In the Protectora vein, approximately 2 kilometers north of the old El Tigre Mine, underground channel sample ETU-1008 returned 528.57 g/t silver equivalent consisting of 378.0 g/t silver and 2.01 g/t gold across a true width of 0.50 meters.
Glenn Jessome, President and CEO of Oceanus reports, “After delivering our maiden 43-101 compliant resource estimate our current ongoing program continues to explore our 28,414 hectare district scale El Tigre Property. These high-grade silver results in the Caleigh, Canon Combination and Protectora Veins further our understanding of the mineralization north of the old El Tigre mine. The results from the mapping and sampling of the underground workings and at surface present a series of high priority drill targets over a 2 kilometer strike length north of the old El Tigre Mine, which we intend to drill.”
As previously press released by Oceanus, drill hole ET-17-144 in the Caleigh Vein returned 0.85 meters of 10,128.9 g/t silver equivalent consisting of 7,338.9 g/t silver, 37.2 g/t gold as well as 2.84% copper, 1.38% lead and 4.06% zinc. The silver equivalent ratio is based on a silver to gold price ratio of 75:1 (Ag:Au) and does not include the copper, lead and zinc values. ET-17-144 was one of the last drill holes of the drill program completed by Oceanus. Drill hole 144 was a step-out hole located approximately 800 meters to the north of the old El Tigre Mine. The mineralized zone consists of several vuggy quartz veins and veinlets carrying galena, sphalerite, chalcopyrite, stromeyerite and pyrite within a strongly silicified and kaolinized alteration zone.
The significant channel sample assay results are set out in the table below with ETU designating underground samples and ETS designating surface samples. (see Figure 1 sample Location Map):

El Tigre Resource Estimate
A maiden resource estimate for the El Tigre Property was reported by Oceanus on September 13, 2017 containing indicated resources of 661,000 gold equivalent ounces at 0.77 g/t (21 g/t silver and 0.51 g/t gold) and inferred resources of 341,000 gold equivalent ounces at 1.59 g/t (88 g/t silver and 0.52 g/t gold). The complete National Instrument 43-101 technical report is available on the Company’s website and on SEDAR under the Company’s profile.
El Tigre Property
The El Tigre Property lies at the northern end of the Sierra Madre gold belt which hosts many epithermal gold and silver deposits including Ocampo, Pinos Altos, Dolores and Palmarejo. In 1896, gold was first discovered on the property in the Gold Hill area and mining started with the Brown Shaft in 1903. The focus soon changed to mining high-grade silver veins in the area with the majority of the production coming from the El Tigre vein. Underground mining on the El Tigre vein extended 1,450 meters along strike and mined on 14 levels to a depth of 450 meters. By the time the mine closed in 1938, it is reported to have produced a total of 353,000 ounces of gold and 67.4 million ounces of silver from 1.87 million tons (Craig, 2012).
The district scale El Tigre Property is approximately 35 kilometers long and comprises 28,414 hectares. The El Tigre gold and silver deposit is related to a series of high-grade epithermal veins controlled by a north-south trending structure cutting across the andesitic and rhyolitic tuffs of the Sierra Madre Volcanic Complex within a broad gold and silver mineralized prophylitic alternation zone. The veins dip steeply to the west and are typically 1 meter wide but locally can be up to 5 meters in width. The veins, structures and mineralized zones outcrop on surface and have been traced for a distance of 5.3 kilometers along strike. Historical mining and exploration activities focused on a 1.5 kilometer portion of the southern end of the deposits, principally on the El Tigre, Seitz Kelly and Sooy veins. Four veins in the north (Aguila, Escondida, Fundadora and Protectora) were explored with only limited amounts of production.
Lab Preparation and Assay
The sealed and tagged sample bags are transported to the ActLabs facility in Zacatecas, Mexico. ActLabs crushes the samples and prepares 200-300 gram pulp samples with ninety percent passing Tyler 150 mesh (106μm). The pulps are assayed for gold using a 50 gram charge by fire assay (Code 1A2-50) and over limits greater than 10 grams per tonne are re-assayed using a gravimetric finish (Code 1A3-50).
Silver and multi-element analysis is completed using 4 acid total digestion (Code 1F2 Total Digestion ICP). Over limits greater than 100 grams per tonne silver are re-assayed using a gravimetric finish (Code 8-Ag FA-GRAV Ag). Over limits greater than 10,000 ppm for copper, lead and zinc are re-assayed using 4 acid total digestion (Code 8-4A AAS) and reported in percent.
Quality Assurance / Quality Control and Data Verification
Quality assurance and quality control procedures monitor the chain-of-custody of the samples and includes the systematic insertion and monitoring of appropriate reference materials (certified standards, blanks and duplicates) into the sample strings. The results of the assaying of the QA/QC material included in each batch are tracked to ensure the integrity of the assay data. All results stated in this announcement have passed Oceanus’ QA/QC protocols.
David R. Duncan, P. Geo., V.P. Exploration of the Corporation, is the Qualified Person for Oceanus as defined under National Instrument 43-101. Mr. Duncan has reviewed and approved the scientific and technical information in this press release and has reviewed the Technical Report.
