Trilogy Metals Reports Drilling Results from the Bornite Project

VANCOUVER, Oct. 9, 2018 /CNW/ - Trilogy Metals Inc. (TSX/NYSE American: TMQ) ("Trilogy Metals" or the "Company") is pleased to announce the first set of high-grade copper and cobalt assay results from this summer's exploration diamond drilling program at the Bornite Project, a part of the Company's Upper Kobuk Mineral Projects ("UKMP") located in the Ambler mining district of Northwest Alaska.  Sample results from these four holes comprise approximately 3,871 meters from the recently completed 10,123 meter drill campaign.  All four drill holes contain copper mineralization and were designed as infill holes to the 300 to 400 meter step-out holes drilled by the Company's previous round of drilling completed in 2017.

At a cutoff grade of 0.5% copper the results are as follows:

• RC18-246 intersected three mineralized intervals of:
• 19.6 metres averaging 2.06% copper;
• 6.1 metres averaging 2.36% copper; and
• 7.6 metres averaging 1.04% copper.

• RC18-243 intersected one mineralized interval of:
• 2.0 metres averaging 2.23% copper.

•  RC18-244 intersected one mineralized interval of:
• 20.4 metres averaging 0.83% copper.

• RC18-247 intersected two mineralized intervals of:
• 20.1 metres averaging 4.55% copper, including 16.4 meters grading 5.34% Copper and 0.21% Cobalt (The results of this mineralized interval were disclosed in the Company's press release dated August 23, 2018); and
• 33.4 metres averaging 0.82% copper.

Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals commented, "We continue to see narrow zones of high-grade copper and cobalt mineralization overlain by broader zones of lower grade mineralization at Bornite.  The continuity of the mineralized envelop continues to impress.  With another eight holes of results due to come out over the next several weeks, we will continue to release results as they become available.  After all results are in, we expect to complete an updated resource estimate at Bornite in the first half of next year."

The 2018 drilling budget of $10 million for Bornite this year was funded entirely by South32 Limited (ASX, LSE, JSE: S32; ADR: SOUHY) ("South32") and represents the second $10 million payment under the Option Agreement with South32 and maintains the Option Agreement in good standing.  In August 2018, South32 agreed to increase its contribution to this year's Bornite drilling program by funding an additional $800,000 to the Company for an increased budget at Bornite totaling $10.8 million, which allowed the Company to expand drilling from 8,000 meters to 10,000 meters this summer.  The additional funding will reduce South32's 2019 minimum exploration budget commitment of $10 million to $9.2 million.  For more information on the Option Agreement see the Company's press release on April 10, 2017 (https://Trilogy PR April 10 2017).

This year's program was comprised of 12 drill holes totaling approximately 10,123 meters through a combination of infill and expansion drill holes in and around the known deposit. The original drilling campaign was budgeted to be 8,000 metres but was subsequently expanded to 10,000 metres with the addition of two more drill rigs. The 2018 program followed up on drilling completed during the 2017 exploration program which was one of the larger programs in the history of drilling at the Bornite Project. During 2017, the Company drilled nine diamond drill holes comprising 8,437 metres to test the extension of the of the currently defined resource^†.

Trilogy Metals has recently completed its summer exploration drilling program at Bornite and geotechnical activities at its Arctic Project. Additional drill results are anticipated to be released regularly over the next couple of months as they become available.  The objective of the 2018 drill campaign is to infill and expand the currently defined open pit and underground mineral resources. 

Results are presented in Table 1 at a cutoff grade of 0.5% copper to be comparable with previous drill results released by the Company.  All the intersected widths are normal to stratigraphy and therefore can be considered to be true widths. Results at a more selective higher-grade cutoff of 1.5% copper are also presented in Table 2 to show locally higher-grade intervals.  Table 3 shows drill hole locations.  Figure 1 shows the location of the drill holes on a plan map and Figure 2 shows a cross-section through drill hole RC18-0246.

Table 3 – Bornite Drill Hole Locations

Mineralization within the Bornite deposit occurs as a series of "Reefs" hosted by both the Upper and Lower Bornite Carbonate sequences separated by generally unmineralized phyllite units. The Cu-Co mineralization at Bornite occurs in three distinct carbonate zones, the Upper Reef, the Lower Reef, and the South Reef.  All three zones were drill tested this year. 

Mineralization is typically observed as breccia matrix replacement and is generally dominated by chalcopyrite and sometimes by bornite with chalcocite – particularly in the higher-grade zones.  Mineralization can also be observed as vein and replacement zones containing chalcopyrite and calcite/dolomite gangue.  These styles of mineralization were observed in all holes mentioned in this press release with bornite, chalcocite mineralization observed in RC18-0247, RC18-0246, and minorly within RC18-0244; and chalcopyrite dominating mineralization observed in RC18-0243.

Bornite Resource

The resource estimate utilized assay data from drill holes completed by the Company between 2011 and 2013 and re-sampled historic holes Kennecott drilled in the 1960s and 1970s. On June 5^th, 2018 the Company announced an updated resource estimate for the Bornite project of 5.5 Billion pounds of copper inferred resource at a grade of 1.74% Cu and 913 Million pounds of copper indicated resource at a grade of 1.02% Cu and total Inferred Cobalt resources (in-pit and below-pit) of 182.4 million tonnes grading 0.019% Co for 77 million pounds of contained cobalt. Trilogy Metals filed a National Instrument 43-101 technical report in July 2018.  See the Bornite Technical Report as well as the Company's press releases dated June 5, 2018 (https://Trilogy PR June 5 2018) and the Company's press release on the filing of the updated NI43-101 Technical Report for Bornite on July 20, 2018 (https://Trilogy PR July 20 2018).

QA/QC Program

The drill program, sampling protocol and data verification were managed by qualified persons employed by the Company. Diamond drill holes were typically collared at PQ or HQ diameter drill core and reduced to HQ and NQ diameter during the drilling process. Samples were collected using a 0.2-metre minimum length, 2.5-metre maximum length and 1.8-metre average sample length. Drill core recovery averaged 87% overall and 94% within the prospective lithologies. Three quality control samples (one blank, one standard and one duplicate) were inserted into each batch of 20 samples. The drill core was sawn, with half sent to ALS Minerals in Fairbanks for sample preparation and the sample pulps forwarded to ALS's North Vancouver facility for analysis. ALS Minerals in North Vancouver, B.C., Canada, is a facility certified as ISO 9001:2008 and accredited to ISO / IEC 17025:2005 from the Standards Council of Canada. The Company will submit 5% of the assay intervals from prospective lithologies to an independent check assay lab.

Cautionary Note to United States Investors

This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this press release have been prepared in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (CIM)—CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended ("CIM Definition Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (SEC), and resource and reserve information contained herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, the term "resource" does not equate to the term "reserves". Under U.S. 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. The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. Investors are cautioned not to assume that all or any part of "measured" or "indicated resources" will ever be converted into "reserves". Investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported by Trilogy Metals in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Arctic does not have known reserves, as defined under SEC Industry Guide 7.  Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
