Oceanus Reports a Wide Zone of 127 Meters of 2.16 g/t Gold Equivalent Consisting of 1.80 g/t Gold and 27.5 g/t Silver at its El Tigre Property in Sonora, Mexico
Mar 07, 2016HALIFAX, NOVA SCOTIA - March 7, 2016 - Oceanus Resources Corporation (TSXV:OCN) ("Oceanus" or the "Company") is pleased to report results from its infill gap sampling program on the legacy diamond drill core at its El Tigre Property. These assay results indicate a broader halo of gold and silver mineralization than previously recognized. This wide zone of gold and silver mineralization, which starts at surface, may have future potential for open pit bulk mining. After Oceanus included the new assay results for the legacy diamond drill holes, the mineralized intercept for select holes are as follows:
- Hole ET-13-051 - 127.0 meters of 2.16 g/t gold equivalent consisting of 1.80 g/t gold and 27.5 g/t silver; including 33.0 meters of 4.73 g/t gold equivalent consisting of 4.48 g/t gold and 18.5 g/t silver
- Hole ET-13-077 - 139.1 meters of 1.02 g/t gold equivalent consisting of 0.94 g/t gold and 6.6 g/t silver
- Hole ET-13-056 - 67.4 meters of 1.67 g/t gold equivalent consisting of 1.07 g/t gold and 44.7 g/t silver
- Hole ET-13-064 - 42.0 meters of 1.53 g/t gold equivalent consisting of 1.10 g/t gold and 32.4 g/t silver
Due to the steep slope of the hillside, many of the legacy drill holes are collared on the mineralization, some have been lost due to the underground workings and others have not fully pierced into the barren footwall. The true width of the drill hole intersections cannot be determined from the information available and further drilling will be required. A table of the drill results and drill sections are presented below.
Glenn Jessome. President and CEO of Oceanus, stated "During acquisition due diligence our team, which has extensive experience in large epithermal deposits in Mexico recognized that the previously unsampled drill core required sampling. We see the greater potential of the El Tigre property as a bulk tonnage target."
Oceanus' initial work program at the El Tigre property entailed the collection of 1,430 samples to fill in the "gaps" in the legacy drill hole assay database to ensure the entire mineralized zones were sampled from the hanging wall to footwall. The new assay results received to date indicate that the mineralized zone at El Tigre approaches true widths of 100 meters. The veins at the El Tigre Property dip steeply to the west. The veins, structures and mineralized zones outcrop on surface and have been traced for a distance of 5.3 kilometers along strike.
For Hole ET-13-051 Oceanus collected 113 continuous samples with the assay results confirming gold and silver grades across the entire 127 meter mineralized section cut by this hole. The hole ended in mineralization. See Figure 1 below.

For Hole ET-13-077 Oceanus collected 31 samples primarily to fill in significant gaps between 28.6 meters and 57.5 meters in the El Tigre Silver sampling. El Tigre had collected only 4 samples in this interval. The Oceanus sampling returned a 19 meter interval averaging 1.95 gpt gold and confirmed continuous mineralization over the 139.1 meters. See Figure 2 below.

Proposed Exploration Program
Before the end of the third quarter of this year Oceanus intends to re-log the existing drill core, complete further in-fill sampling of unsampled drill core, and complete mapping and sampling of both the surface and underground. The Company intends to design and complete a follow on drilling program that's primary focus will be to explore the newly recognized wide zone of mineralization.
El Tigre Acquisition
On November 13, 2015 Oceanus and El Tigre closed the transaction that combined their respective companies by way of a statutory plan of arrangement pursuant to the Business Corporations Act (British Columbia). Oceanus acquired all of the outstanding common shares of El Tigre Silver Corp. in exchange for common shares of Oceanus. On December 23, 2015 Oceanus completed a non-brokered private placement raising aggregate proceeds of $2,600,000.
El Tigre Property
The El Tigre Property lies at the northern end of the Sierra Madre gold belt which hosts many of the larger multi-million ounce 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 El Tigre Property is approximately 35 kilometers long and comprises 21,842.78 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.
Past Drilling Programs
From 1981 to 1984, Anaconda Minerals Company completed an extensive district scale exploration program including geological mapping, test work on the tailings as well as drilling 7,812 meters in 22 holes.
From 2011 to 2013 El Tigre Silver drilled a total of 59 diamond core holes totaling 9,411 meters of drill length to test the potential of the Sooy, El Tigre and Seitz-Kelly veins over a distance of about 1,500 m from the Espuelas Canyon to the Gold Hill area.
El Tigre Mineral Resource
Hard Rock Consulting, LLC of Lakewood, Colorado ("HRC") completed a NI 43-101 report titled "NI 43-101 Technical Report, Preliminary Feasibility Study for the El Tigre Silver Project, Sonora Mexico", filed by El Tigre Silver Corp. on August 15, 2013 with an effective date of June 1, 2013 (the "Technical Report"), which defines an resource at the El Tigre Property. The mineral resource estimate for in-situ material is based on 9,468 meters drilled in 61 diamond core holes conducted in three phases over three years. The mineral resources for the in-situ portion of the El Tigre Project are estimated by HRC to be 9.875 million tonnes grading an average of 0.630 g/t Au and 39.7 g/t Ag classified as indicated mineral resources with an additional 7.042 million tonnes grading an average of 0.589 g/t Au and 36.1 g/t Ag classified as inferred mineral resources. Expressed in terms of Equivalent Gold using a price ratio of 1 g/t Au equals 75 g/t Ag ("EqAu75"), the indicated resource contains 368,000 ounces of EqAu75 and the inferred resource contains 242,000 ounces of EqAu75. Additional information about the mineral resource estimates is included in the Company's Management's Discussion & Analysis for the three and nine months ended December 31, 2015. To the best of the Company's knowledge, information and belief, there is no new material scientific information or technical information that would make the disclosure of the mineral resources or mineral reserves inaccurate or misleading.
Lab Preparation and Assay
The diamond drill core (HQ size) from the 2011 to 2013 El Tigre Silver programs has been stored inside the secure core storage facility. Portions of the drill core from the 1982 and 1983 Anaconda drilling programs are also stored inside the core storage facility. The core is geologically logged, photographed and marked for sampling. When the sample lengths are determined the full core is sawn with a diamond blade core saw with one half of the core being bagged and tagged for assay. The remaining half portion is returned to the core trays for storage and or for metallurgical test work. In sections where the core had been previously sampled, the witness core was sawn in half (quartered) and the remaining quarter is returned to the core trays for storage.
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 total digestion (Code 1F2 Total Digestion ICP).

Cautionary Note to US Investors
The disclosure on this Website has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws. Disclosure, including scientific or technical information, has been made in accordance with Canadian National Instrument 43-101 -- Standards of Disclosure for Mineral Projects ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. As a result, information contained on this Website containing descriptions of the mineral properties or estimates of mineral reserves or resources of Silver Tiger is not comparable to similar information disclosed by U.S. companies in reports filed with the SEC.
For example, the terms "measured mineral resources", "indicated mineral resources", "inferred mineral resources", "proven mineral reserves" and "probable mineral reserves" are used on this Website to comply with the reporting standards in Canada. While those terms are recognized and required by Canadian regulations, the SEC does not recognize them.
Under the rules and regulations of the SEC set forth in Industry Guide 7, a U.S. company may only disclose estimates of proven and probable mineral reserves, and may not disclose estimates of any classification of mineral resources. In addition, the definitions of proven and probable mineral reserves used in NI 43-101 differ from the definitions in the SEC Industry Guide 7. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Investors are cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into mineral reserves. Any estimate of mineral reserves or resources has a great amount of uncertainty as to its existence, and great uncertainty as to its economic and legal feasibility with estimates of mineral resources having a greater degree of uncertainty. It cannot be assumed that all or any part of measured mineral resources, indicated mineral resources or inferred mineral resources will ever be upgraded to a mineral reserve or mined. Further, in accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies. Investors are cautioned not to assume that any part of the reported measured mineral resources, indicated mineral resources, or inferred mineral resources on this Website will ever be classified as a reserve. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute reserves as in place tonnage and grade without reference to unit measures.
