Trevali Announces Drill Results along the North Limb at Caribou Mine Extending Mineralization to the North

VANCOUVER, British Columbia, Jan. 06, 2020 (GLOBE NEWSWIRE) — Trevali Mining Corporation (“Trevali” or the “Company”) (TSX: TV; OTCQX: TREVF) is pleased to announce results from the 2019 infill drill program at the Caribou Zinc-Lead-Silver Mine in the Bathurst Mining Camp, New Brunswick, Canada. The surface drilling campaign, which focused on delineation and conversion of Inferred Mineral Resources to Indicated Mineral Resources north of current Mineral Reserves, has intersected several zones of economical Zn-Pb-Ag mineralization. This indicates that mineralization, is wider than previously interpreted in portions of the North Limb and continues at mineable depths towards the north.


  • Hole BR-1047 intersected 4.19 metres at 7.91% Zn, 2.54% Pb and 66.50 g/t Ag.
  • Hole BR-1047A intersected 23.00 metres at 5.84% Zn, 1.93% Pb and 69.25 g/t Ag.
  • Hole BR-1047B intersected 29.01 metres at 6.24% Zn, 2.33% Pb and 63.05 g/t Ag.
  • Hole BR-1048 intersected 68.74 metres at 7.19% Zn, 2.57% Pb, and 86.45 g/t Ag.
  • Hole BR-1048A intersected 9.00 metres at 7.11% Zn, 2.86% Pb, and 82.69 g/t Ag.

Caribou North Limb delineation

During the fall of 2019, Trevali completed 3,815 metres of drilling on the Caribou North Limb, with the goal of increasing confidence in the geological model. Previous drilling campaigns by Trevali in this area had intersected locally higher-grade mineralization, notably in drill holes BR-1014A and BR-1030. The northern portion of Caribou North Limb was classified as Inferred Mineral Resources and a surface drilling campaign was completed with the focus on upgrading the Mineral Resource to Indicated near to planned mine development as well as testing areas around previous well-mineralized drill intercepts.

Figure 1: 3-D view of North Limb of the Caribou deposit, looking east with 2019 Trevali drilling along with 2018 year-end Mineral Resource classification is available at

Assay results from the drill program are summarized in Table 1. The drill program is expected to further increase the geological confidence of the currently defined Inferred Mineral Resource on the North Limb and will support long term mine development decisions.  Of particular note are holes BR-1047A, BR-1047B, BR-1048, and BR-1048A which help to define a zone of thick (±15-30m) and higher-grade (>7.5% Zn+Pb) mineralization around 2015 drill hole BR-1014A (2015-04-16_NR), see Figure 1. The large Inferred Mineral Resource currently defined on the northern portion of the North Limb requires further definition drilling to delineate its extents towards along strike as well as at depth.

Regional exploration

Regional exploration during 2019 has focused on advancing regional targets on Trevali’s greenfield properties, more specifically Heath Steele East and Murray Brook South.

At Heath Steele East, the 2019 expansion of a ground gravity survey initially completed in 2017 has furthered the geological understanding of the property and identified several anomalies associated with geologically favorable horizons for further testing.

At Murray Brook South, a time-Domain Electro-Magnetic (“TDEM”) survey was completed over portions of the Murray Brook South claim in order to refine targets for drill testing in December 2019, results are pending. Trenching performed in 2018 as part of a joint venture agreement between Puma Exploration and Trevali discovered a narrow gossan within the Mount Brittain formation, which hosts the Murray Brook deposit located 1.5km to the north-east. A drilling program is currently underway to test the Murray Brook South anomalies.
