The most recent Annual Survey of Mining Companies by the Fraser Institute ranked British Columbia seventh among Canadian mining jurisdictions. But no other province or territory has had two new precious metal mines reach commercial production less than 15 months apart over the last two calendar years.<\/p>\n

In July 2017, Pretium Resources (TSX: PVG; NYSE: PVG) launched commercial production at its high-grade Brucejack gold mine in B.C.\u2019s Golden Triangle, 60 km north of Stewart, British Columbia. Pretium\u2019s Brucejack mine delivered 96,300 oz. gold in the fourth quarter to bring total gold production in the second half of 2018 to 188,983 oz. gold, or 95% of the low end of its 200,000 oz. production guidance.<\/q><\/p>\n

About 14 months later, Coeur Mining\u2019s (NYSE: CDE) Silvertip silver-zinc-lead mine in northwestern B.C. reached the same milestone.<\/p>\n

And not far from Brucejack, near Stewart, IDM Mining (TSXV: IDM; US-OTC: IDMMF) received its provincial environmental assessment certificate for the Red Mountain gold project, as well as a positive federal environmental assessment decision.<\/p>\n

Brucejack consists of the Valley of the Kings deposit, which had been discovered in 2009 by Silver Standard Resources.<\/p>\n

Under the guidance of former Silver Standard president and CEO Robert Quartermain, now Pretium chairman, Pretium had its initial public offering in 2010, and secured the rights to Brucejack.<\/p>\n

High-grade, gold-silver mineralization at the Valley of the Kings occurs in steeply dipping and predominantly east- to northwest-trending quartz stockwork veins and breccia zones, inside a broader halo of clay alteration and low-grade mineralization.<\/p>\n

The result is that the gold mineralization is \u201cnuggety,\u201d which makes it hard to mill with predictable output.<\/p>\n

The company watched its stock price plummet in 2017, as it struggled to reach planned production levels. But by 2018 gold production numbers climbed closer to expectations, at least until the fourth quarter.<\/p>\n

Pretium\u2019s Brucejack mine delivered 96,300 oz. gold in the fourth quarter to bring total gold production in the second half of 2018 to 188,983 oz. gold, or 95% of the low end of its 200,000 oz. production guidance.<\/p>\n

The Brucejack mine produced 376,000 oz. for all of 2018, or 97% of its guidance.<\/p>\n

In a note titled \u201cQ4 falls short \u2014 again,\u201d BMO Capital Markets analyst Andrew Kaip wrote that the production miss was \u201cattributable to lower-grade reconciliation with the 11.5 gram-per-tonne gold grade achieved during Q4\/18, well below our estimate for 14.5 grams. To compensate, PVG looks to have pushed tonnes, as 267,000 tonnes milled was above our expectation for 239,000 tonnes \u2026 we now expect Q4 earnings per share, cash flow per share and free cash flow estimates to decline by an average of 30%, and full-year 2018 by an average of 8%.\u201d<\/p>\n

Pretium seeks to refine its grade-control program over the coming quarters to improve short-term grade predictability. One method could include longitudinal long-hole stoping.<\/p>\n

\u201cThe high variability of the gold mineralization throughout the Valley of the Kings deposit is a key characteristic of the Brucejack mine, and gold production is managed with grade control, the sequence of the mine plan and the availability of stopes for optimal grade blending,\u201d Pretium president and CEO Joseph Ovsenek said in a release. \u201cWe will build on what we have learned mining the gold mineralization at the Valley of the Kings over the first six quarters of production to further refine our grade-control program and mining methods.\u201d<\/p>\n

Joe Mazumdar, an analyst at the newsletter Exploration Insights, talked about grade reconciliation at the Valley of Kings deposit during an interview on Episode #29 of The Northern Miner Podcast.<\/p>\n

\u201cThe grade reconciliation \u2026 depends on the time period you\u2019re talking about. If you talk about a month, the [grade] reconciliation can be very volatile. Over the life of the mine, it might actually meet what the reserves say. But day to day, week to week, month to month, it may not,\u201d Mazumdar said.<\/p>\n

Ovsenek said the company plans to update the reserve and resource numbers, and grade reconciliation, early in 2019.<\/p>\n

At the end of 2018, Pretium had $45 million in cash after buying back its gold-streaming contract from Osisko Gold Royalties (TSX: OR; NYSE: OR), which had bought it from Orion Mine Finance Group.<\/p>\n

The company also received permits to boost daily tonnage 3,800 tonnes, up from 2,700.<\/p>\n

BMO has an \u201coutperform\u201d rating on Pretium and a 12-month target of $17.50.<\/p>\n

Silvertip<\/h3>\n

In October 2017, Chicago-based silver and gold miner Coeur Mining bought Silvertip in a $200-million cash-and-share deal for JDS Silver.<\/p>\n

At the time only 5% of the 370 sq. km Silvertip land package had been explored. Another $50 million is payable once Coeur reaches exploration and permitting milestones.<\/p>\n

\u201cWe look forward to continuing our exploration efforts to expand the size of this prospective, high-grade deposit, and further extend the mine life,\u201d said Mitchell J. Krebs, Coeur\u2019s president and CEO, in a release.<\/p>\n

Silvertip hosts 1.61 million proven and probable tonnes grading 289 grams silver per tonne, 8.2% zinc and 5.6% lead for almost 15 million oz. silver, 292.7 million lb. zinc and 198.65 million lb. lead.<\/p>\n

The project hosts another 1.17 million measured and indicated tonnes grading 223 grams silver per tonne, 8.6% zinc and 4.1% lead for 8.42 million oz. silver, 222.48 million lb. zinc and 105.9 lb. lead.<\/p>\n

Coeur milled 86,000 tonnes at Silvertip in 2018, just less than half of which was done in the fourth quarter. The mine officially reached commercial production on Sept. 1.<\/p>\n

In 2018, the mine produced 340,000 oz. silver, 6.78 million lb. zinc and 3.91 million lb. lead in concentrate, well below the company\u2019s 2018 guidance of 700,000 to 1.2 million oz. silver.<\/p>\n

Coeur continues to work towards its 1,000-tonne-per-day target by the end of March. Throughput stands at 631 tonnes per day.<\/p>\n

Added Krebs: \u201cWe have made substantial progress over the past 14 months since acquiring Silvertip, and will carry that momentum into 2019.\u201d<\/p>\n

In a Jan. 14 note, BMO silver analyst Ryan Thompson wrote that operationally in the fourth quarter, Coeur showed \u201csolid production from Kensington, Rochester and Palmarejo, which was offset by weaker production at Wharf and Silvertip \u2026 [and] we are lowering our target price to US$6.50, as we have updated our Silvertip model with the Dec. 27 technical report results.<\/p>\n

Positively, Q4 showed progress at Silvertip vs. Q3, and so far in 2019, the plant has achieved 631 tonnes per day month-to-date vs. 391 tonnes per day in the fourth quarter.\u201d<\/p>\n

Red Mountain<\/h3>\n

Nearby in B.C.\u2019s Golden Triangle, IDM Mining is moving ahead with its Red Mountain underground gold project near Stewart.<\/p>\n

However, in January Ascot Resources (TSXV: AOT, US-OTC: AOTVF) announced a bid to acquire all of the issued and outstanding shares of IDM in a friendly, all-share deal. Each IDM shareholder will receive 0.0675 of an Ascot share for each share of IDM held. The deal valued IDM at 8.6\u00a2 per share as the bid was launched.<\/p>\n

\u201cThis combination provides a critical mass and optionality for development of multiple high-grade gold deposits, which will result in significant stakeholder benefits for citizens of the Nisga\u2019a Nation, for my hometown of Stewart, and for my friends in the border town of Hyder. The combined company will control two geological trends hosting significant exploration ground in the Golden Triangle,\u201d said IDM president and CEO Robert McLeod in a release.<\/p>\n

Red Mountain hosts a measured and indicated resource of 2.77 million tonnes grading 7.91 grams gold per tonne and 22.75 grams silver, for 704,600 oz. gold and 2.026 million oz. silver. There are another 316,000 inferred tonnes at 6.04 grams gold and 7.61 grams silver, for 61,400 oz. gold and 77,200 oz. silver.<\/p>\n

The Canadian Environmental Assessment Agency recently issued a positive decision for the wholly-owned Red Mountain gold-silver project.<\/p>\n

The federal agency said Red Mountain is \u201cnot likely to cause significant adverse environmental effects, and the project may proceed,\u201d but it is subject to 120 conditions that IDM must fulfill throughout the life of the Red Mountain project.<\/p>\n

Vancouver-based Ascot is developing the Premier gold project nearby, and says it launched its bid for IDM \u201cto create the leading high-grade gold development and exploration company\u201d in B.C.\u2019s Golden Triangle, and that the combined entity will \u201cbenefit from numerous operational and development synergies.\u201d<\/p>\n
