Trevali drills significant zinc-lead mineralization at Halfmile deposit

14.06.2017  |  Marketwired

Highlights include: 110.5 metres(i) of 7.86% Zn and 2.34% Pb, including

37.2 metres(i) of 11.38% Zn and 4.05% Pb;

Also, 22.1 metres(i) of 10.71% Zn, 4.16% Pb and 69.97 g/t Ag


VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jun 14, 2017) - Trevali Mining Corp. ("Trevali" or the "Company") (TSX:TV)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI) announces results from its 2016-2017 resource definition drill program on its Halfmile deposit in the Bathurst Mining Camp of northeastern New Brunswick. The program was designed to validate historic data as well as to expand and improve upon the existing geological model. Trevali completed 28 holes (15,175 metres) testing a variety of targets within and around the Upper and Lower Zones of the Halfmile deposit that remains open for expansion.

The Halfmile deposit has a currently defined Indicated Resource of 6.26 million tonnes grading 8.13% Zn, 2.58% Pb, 0.22% Cu, and 30.8 g/t Ag, and an additional Inferred Resource of 6.08 million tonnes at 6.69% Zn, 1.83% Pb, 0.14% Cu and 20.5 g/t Ag. The 2016-17 Halfmile drill program was initiated with a variety of goals:

  • Validate the historic drilling and geological model in the Lower Zone of the deposit

  • Define limits of mineralization

  • Test geologic and geophysical exploration targets in the general vicinity of the currently defined mineralization

  • Collect geotechnical data for future engineering and mine planning studies

  • Test working geologic interpretations / models

In general, results from the 2016-2017 drilling campaign corroborates the historic drilling completed on the project. This latest drilling dramatically increases Trevali's confidence in the resource model and provides further information about precious metal values in the Upper and Lower Zones as previous drill programs did not consistently analyze for silver or gold. The recent drilling has also facilitated an improved understanding of the local geology and thus allowed for a more realistic model of mineralization that will ultimately facilitate future engineering studies.

Audio Magnetotelluric ("AMT') Survey:

An orientation AMT survey was also completed over Halfmile with the goal of testing the efficacy of this geophysical method as an exploration tool. Initial results are promising with the survey clearly identifying known mineralization over 800-metres below ground surface ("BGS"). The program also identified a possible new deep target approximately 800-metres below the North Zone, however, additional geophysical infill is required to better define this area (Figure 4).

Halfmile is a fully permitted mine with infrastructure in place including underground production development, water treatment facilities and a camp. In 2012 Trevali mined approximately 120,000 tonnes of mineralized material from Halfmile and processed it on a toll mill-basis at Xstrata's nearby Brunswick 12 mill complex prior to its ultimate closure in 2013. During this period the Halfmile trial operation produced saleable zinc, lead-silver and copper-gold concentrates.

In 2016, a new independent Preliminary Economic Assessment ("PEA") engineering study by SRK Consulting Engineers commenced on the Company's Halfmile and Stratmat deposits in New Brunswick. The study is examining development strategies for the deposits including the potential for a stand-alone milling solution. The PEA is anticipated to be completed imminently and will direct the Companies medium term strategy for the region where it owns the largest repository of undeveloped massive sulphide deposits in the prolific Bathurst Mining Camp.

Qualified Person and Quality Control/Quality Assurance

EurGeol Dr. Mark D. Cruise, Trevali's President and CEO and Daniel Marinov, P.Geo, Trevali's VP Exploration, are qualified persons as defined by NI 43-101, have supervised the preparation of the scientific and technical information that forms the basis for this news release. Mr. Marinov is responsible for all aspects of the work, including the quality control/quality assurance programs. Dr. Cruise is not independent of the Company, as he is an officer, director and shareholder. Mr. Marinov is not independent of the Company as he is an officer and shareholder. On-site personnel at the project rigorously collect and track samples which are then security sealed and shipped to Bureau Veritas Laboratories (Bureau Veritas) preparation facility in Timmins, ON for crushing and splitting then the pulp samples are shipped to Vancouver, B.C. for assay. Zinc, lead, copper gold and silver, assays were obtained by four acid Aqua-Regia dissolution followed by Inductively coupled plasma optical emission spectrometry (ICP-OES) measurements. Values of Zinc, lead and copper over 10% are assayed by volumetric method. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. Blind certified reference material is inserted at regular intervals into the sample sequence by Trevali personnel in order to independently assess analytical accuracy. Bureau Veritas' quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Finally, representative blind duplicate samples are routinely forwarded to an ISO compliant third party laboratory for external quality control.

Investors are cautioned against attributing undue certainty or reliance on forward-looking statements. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. The Company does not intend, and does not assume any obligation, to update these forward-looking statements or information to reflect changes in assumptions or changes in circumstances or any other events affecting such statements or information, other than as required by applicable law.

Trevali's production plan at the Caribou Mine is based only on measured, indicated and inferred mineral resources, and not mineral reserves, and does not have demonstrated economic viability. Trevali's production plan at the Santander Mine is based only on measured, indicated and inferred mineral resources, and not mineral reserves, and does not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is therefore no certainty that the conclusions of the production plans and Preliminary Economic Assessment (PEA) will be realized. Additionally, where Trevali discusses exploration/expansion potential, any potential quantity and grade is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

We advise US investors that while the terms "measured resources", "indicated resources" and "inferred resources" are recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize these terms. US investors are cautioned not to assume that any part or all of the material in these categories will ever be converted into reserves.
