US Cobalt Drilling Intersects High Grade Cobalt and Discovers New Thicker Mineralized Zones
Hole IC17–19 intersects true thickness 19.1 feet (5.8 meters) grading 0.46% CoEq (0.43%Co+0.30%Cu) within 61.2 feet (18.7 meters) grading 0.37% CoEq (0.30%Co+0.67%Cu)
VANCOUVER, British Columbia, Jan. 15, 2018 (GLOBE NEWSWIRE) -- US Cobalt Inc. (the "Company") (TSXV:USCO) (Frankfurt:26X) (OTCQB:USCFF) announces analytical results from a further seven surface core holes drilled during 2017 at the Iron Creek project (the "Property") in Idaho, USA. All seven of these core holes encountered sulfide mineralization with significant cobalt values. Several of the holes have discovered much thicker cobalt-bearing zones not previously identified at Iron Creek. These mineralized zones occur in the footwall of the main No Name Zone. The interpretation of these results are allowing the expansion of the Company’s search for cobalt mineralization outward from the previously targeted areas.
The objective of the 40-hole, 2017 drilling campaign is to confirm the historical estimates of cobalt mineralization (see Company news release - September 7, 2016). The historical estimates are comprised of two zones with a gap along strike of approximately 400 feet (122 meters) between them. Hole IC17–19, located in this area, intersected a true thickness of 19.1 feet (5.8 meters) grading 0.46% CoEq (0.43%Co+0.30%Cu). This intercept lies within a true thickness of 61.2 feet (18.7 meters) grading 0.37% CoEq (0.30%Co+0.67%Cu). [CoEq = Cobalt Equivalent; calculated as copper/10.58=CoEq]. IC17–19 indicates the potential continuity of mineralization between the two areas of the historical estimates. Results of five additional holes completed in this gap will be released as they become available.
Significant intervals (true thickness) in the current seven drill holes include:
- IC17-19: 19.1 feet (5.8 meters) grading 0.46% CoEq. (0.43%Co+0.30%Cu) within
--61.2 feet (18.7 meters) grading 0.37% CoEq. (0.30%Co+0.67%Cu)
- IC17-16: 9.3 feet (2.8 meters) grading 0.56% CoEq. (0.18%Co+4.05%Cu) within
--21.9 feet (8.9 meters) grading 0.36% CoEq. (0.14%Co+2.39%Cu)
- IC17-17: 23.1 feet (7.0 meters) grading 0.37% CoEq. (0.37%Co+0.001%Cu) within
--78.2 feet (23.8 meters) grading 0.20% CoEq. (0.20%Co+0.001%Cu)
- IC17-18: 4.7 feet (1.4 meters) grading 0.64% CoEq. (0.64%Co+0.02%Cu)
- IC17-20: 8.9 feet (2.7 meters) grading 0.44% CoEq. (0.16%Co+3.02%Cu) within
--47.4 feet (14.4 meters) grading 0.20% CoEq. (0.07%Co+1.42%Cu)
Additional previously unknown thicker intervals (true thickness) include:
- IC17-14: 116 feet (35.4 meters) grading 0.12% CoEq. (0.09%Co+0.34%Cu) incl.
- IC17-16: 74.6 feet (22.7 meters) grading 0.18% CoEq. (0.16%Co+0.18%Cu) incl.

--18.1 feet (5.5 meters) grading 0.26% CoEq. (0.25%Co+0.07%Cu)
Sr. Vice President, Exploration, Brian Kirwin commented: "These exciting drill results continue to instill confidence in the historic work conducted by Noranda and Cominco, among others. The current results are very encouraging with respect to our goal of confirming the historic estimates. These drill results also indicate that mineralization may be continuous between the two zones which comprise the historic estimates. Further, the results confirm newly discovered cobalt-bearing zones in the footwall of the main No Name Zone, which will be targeted in our upcoming drilling. In response to the several very wide intercepts, the Company is expanding its sampling protocols."
Wayne Tisdale, President, commented: "These are further excellent drill results, from one of the very few active cobalt drilling programs in North America. With cobalt prices near $34 per pound, near 8 year highs, Iron Creek is showing expanding potential and we are excited to continue exploration at the project, with drilling from underground expected to begin imminently.”
US Cobalt is conducting the first exploration program at Iron Creek in several decades. The Iron Creek Property covers a west-northwest striking, steeply northerly dipping mineralized zone named the No Name Zone which contains cobalt and copper mineralization in sulfides. The 2017 surface drilling campaign is complete and analysis of the samples continues. The 2017 drilling consists of 40 drill holes with a combined length of approximately 35,000 feet. The Company is building the geological and grade models for resource estimation. In anticipation of completing a resource estimate during 2018, the company has started density testing, mineralogical investigations, and will soon initiate metallurgical testing.

As previously announced, The Project is leased from Chester Mining Company subject to the Company's buy-out rights.
As previously announced, historic tonnage and grade estimates indicate that the Property contains 1,279,000 tons grading 0.59% cobalt – please refer to the Company's news release dated September 7, 2016. Due to the age of the geological work done to establish current anticipated tonnage, the Company is treating these tonnage and grade estimates as historical estimates. The historical estimates do not use categories that conform to current CIM Definition Standards on Mineral Resources and Mineral Reserves as outlined in National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101") and have not been redefined to conform to current CIM Definition Standards. They were prepared in the 1980s prior to the adoption and implementation of NI 43-101. The historical estimates are contained within a report entitled "Iron Creek Prospect, Lemhi County, Idaho (#0483) Progress Report" by Terry A Webster and Thomas K Stump for Noranda Exploration, Inc., July 1980, which report does not detail cut-off grades and metal prices used to estimate the historical mineralization and used a tonnage factor of 11 cubic feet per ton. A qualified person has not done sufficient work to classify the historical estimates as current mineral resources and the Company is not treating the historical estimates as current mineral resources. More work, including, but not limited to, drilling, will be required to confirm the estimates to current CIM Definition Standards. Investors are cautioned that the historical estimates do not mean or imply that economic deposits exist on the Property. Other than as provided for in this press release, the Company has not undertaken any independent investigation of the historical estimates or other information contained in this press release nor has it independently analyzed the results of the previous exploration work in order to verify the accuracy of the information. The Company believes that the historical estimates and other information contained in this press release are relevant to continuing exploration on the Property because they identify significant mineralization that will be the target of the Company's exploration program.
The drill samples and underground channel samples are collected by Company personnel or contractors working for the Company at the drill or portal. All of the Company's facilities are kept secure. The core is transported to the Company's core processing facility in Challis operated by Earl Waite and Sons Mining Contractors who are contracted by the Company. There the core is logged, cut and sampled and subsequently delivered to the laboratory. All facilities are secure.
All core is logged for recovery and other geotechnical features, prior to being sawed lengthwise in half by the Company's contractors. Individual core samples are selected on a geological basis to characterize mineralization. The core is geologically logged and half core is stored on site as reference samples in a secure facility. The samples are bagged, labeled and tied at the core processing facility by the Company's contractors. Geologic information is recorded on standardized sample description forms which included color, rock type, alteration, mineral species and abundance. Samples are stored in a secure facility at the core processing site until delivered to the laboratory. Blanks, duplicates and standards are inserted at the core processing site as part of the QA/QC program. The drill samples were loaded directly from the core processing facility the truck of a shipping company and driven directly to the laboratory where the lab took custody directly from a Company employee. The sampling was overseen by Brian Kirwin, Senior Vice President Exploration for the Company.
American Assay Laboratories (AAL) in Sparks, Nevada conducted the analyses of the drill core samples, and analyzed the Company's QA/QC samples at the same time, and the Company plans to utilize the services of AAL for the core samples. AAL is ISO / IEC 17025 certified and has successfully completed Canadian proficiency testing (CCRMP). Approximately 24% of the samples analyzed are control samples consisting of checks, blanks, and duplicates inserted by the Company - this is in addition to the control samples inserted by the lab. Correlation of the standards with expected values were excellent. At the AAL laboratory, the drill core samples were dried, weighed crushed to 85 % passing -6 mesh, roll crushed to 85% passing -10 mesh, split 250 gram pulps, then pulverized in a closed bowl ring pulverizer to 95 % passing -150 mesh, then analyzed by a 5 acid digestion for ICP analysis.
Mr. Garry Clark, P. Geo., of Clark Exploration Consulting, is the "qualified person" as defined in NI 43-101, who has reviewed and approved the technical content in this press release.
