Introduction:

Newfoundland

The 100%-owner South Tally Pond property is located in central Newfoundland, approximately 90 kilometres southwest of Grand Falls-Windsor (pop. 15,000) and 30 kilometres south of Millertown (pop. 100). The property hosts the Lemarchant Cu-Pb-Zn-Ag-Au volcanogenic massive sulphide (VMS) deposits, along with numerous other VMS prospects and occurrences that remain to be further explored.

The property area is accessible by well-maintained logging/mining roads originating from paved highway at Millertown. Secondary logging roads and logging trails provide good access to various parts of the property, including truck access to the Lemarchant Deposit area. The property is located adjacent to and immediately southwest of Teck Resources Ltd's recently closed (June 2015) Duck Pond Cu-Zn mine.

Property Highlights:

  • Large, 100%-owned land position located adjacent to the recently closed Duck Pond copper-zinc mine (Teck Resources Ltd.)
  • Highly prospective, producing volcanic belt with numerous, underexplored copper-lead-zinc-silver-gold VMS targets.
  • 96 drillholes totalling 32,596 metres completed at Lemarchant Cu-Pb-Zn-Ag-Au Deposit;

    • 1.65% Cu, 12.74% Zn, 3.27% Pb, 185.75 g/t Ag and 10.13 g/t Au over 7.0 metres
    • 1.61% Cu, 11.83% Zn, 3.27% Pb, 528.31 g/t Ag and 3.13 g/t Au over 10.3 metres
    • 1.40% Cu, 14.80% Zn, 3.56% Pb, 80.90 g/t Ag and 1.35 g/t Au over 17.05 metres
  • Initial NI 43-101 mineral resource estimate on Lemarchant “Main Zone” in 2012.
  • Lemarchant Deposit is defined to 210 metres depth and remains open along strike and to depth.
  • Newly discovered Northwest Zone by 2013 drilling remains open for expansion.

Exploration History

IMG 0237 thumbThe bulk of the exploration work in the South Tally Pond area was undertaken by Noranda and its various partners from 1973 to 1998. Geological, geochemical and geophysical surveys were conducted by Noranda throughout the Tally Pond area and resulted in the discovery of several base metal VMS deposits (Duck Pond, Boundary) plus numerous base metal prospects (e.g. Burnt Pond, Moose Pond, Lemarchant, and Rogerson Lake). Noranda completed soil sampling, ground geophysical surveys, limited trenching and 14 drillholes (3,018 metres) at the Lemarchant prospect between 1981-1982 and 1991-93.

Following the discovery of Duck Pond deposit in 1983, Noranda focussed a majority of its exploration efforts at Duck Pond which resulted in a pre-feasibility study on the Duck Pond and Boundary deposits in 1998. The work outlined a non-43-101 compliant “diluted mineable ore reserves” of 4.2 million tonnes grading 3.2% Cu, 5.5% Zn, 57g/t Ag and 0.9g/t Au, including approximately 500,000 tonnes at the Boundary Deposit. Thundermin Resources Inc. and Queenston Mining Inc. acquired the Duck Pond/Boundary property from Noranda and completed a revised reserve estimate and bankable feasibility study for the Duck Pond and Boundary Deposits in 1999. Their work highlighted a 43-101-compliant measured and indicated mineral resources of 5.1 million tonnes averaging 3.6% Cu, 6.3% Zn, 1.0% Pb, 64 g/t Ag and 0.9 g/t Au for both the Duck Pond and Boundary Deposits.

In 2002, Aur Resources Limited acquired 100% interest in the Duck Pond property. Aur Resources made a positive production decision in December 2004 and achieved commercial production in April 2007. In late 2007, Teck Resources Limited purchased Aur Resources and took over ownership and operatorship of the Duck Pond Mine.

IMG 0225 thumbIn late 2006, Paragon Minerals Corporation acquired all the Newfoundland assets from Rubicon Minerals Corporation through a plan of arrangement. Following the arrangement, Paragon Minerals assembled the South Tally Pond property immediately southwest of the Duck Pond Mine and has completed airborne geophysics, geological mapping and prospecting, and diamond drilling. Following the discovery of massive sulphides at the Lemarchant prospect in 2007, a majority of the exploration work focused on this area.

Between 2007 and 2011, Paragon Minerals Corporation completed 21,259 metres of diamond drilling in 60 drillholes at the Lemarchant Prospect. The drilling outlined a significant semi-massive to massive sulphide zone over a 300 metre strike length between sections 101N to 104N (the “Main Zone”). An initial National Instrument 43-101 resource estimate was completed on the Lemarchant Main Zone mineralization in January, 2012, using a 7.5% zinc equivalent grade cut-off.

Paragon Minerals was acquired by Canadian Zinc Corporation in September 2012, and operates as a 100% subsidiary of Canadian Zinc Corporation. In 2013, Canadian Zinc completed 8,300 metres of drilling in 26 drillholes at the Lemarchant Deposit, leading to the discovery of the Northwest massive sulphide zone at the Lemarchant deposit.

Property Geology:

The South Tally Pond property is situated in Tally Pond volcanic belt, one of several Cambro-Ordovician volcanosedimentary belts in central Newfoundland that collectively make up the Victoria Lake Supergroup. The Tally Pond volcanic belt forms a 50 kilometre long by up to 10 kilometres wide, northeast trending linear belt that extends from Victoria Lake in the southwest to Sandy Lake in the northeast. The Tally Pond volcanic belt is host to Teck Resource's Duck Pond Cu-Zn mine, the Lemarchant Deposit and numerous other base metal prospect and occurrences.

Geological mapping in the Lemarchant area has outlined a broad zone (4000 by 700 metre) of VMS-style hydrothermal alteration in the felsic volcanic rocks. At depth, the felsic volcanic rocks are the host and footwall to the Lemarchant massive sulphide mineralization. The rocks typically consist of felsic volcanic breccias, flows, lapillistone and lapilli tuffs. The footwall alteration to the massive sulphide mineralization varies from moderate to intense silicification, sericitization, chloritization and barium-enrichment with disseminated to semi-massive stringer pyrite, sphalerite, galena, chalcopyrite and lesser pyrrhotite and bornite. Gold and silver contents are high with occasional visible gold. The mineralized intervals are often accompanied by massive, mineralized barite zones. Lithogeochemical analyses of the altered felsic volcanic rocks have alteration indices (Ishikawa, ACNK, Ba/Sr) comparable to the alteration surrounding the Duck Pond and Boundary deposits.

The felsic volcanic rocks are conformably overlain by mafic volcanic rocks to the east. The contact is typically marked by a pyrite and/or pyhrrotite-bearing mudstone horizon measuring from <1 metres to 3 metres in thickness. A west-dipping, east-verging thrust fault, the Lemarchant Fault is interpreted to cut the mineralization and underlying footwall sequence. The Lemarchant Fault displaces a thick succession of felsic-mafic volcanic rocks over mafic volcanic rocks that closely resemble the hangingwall mafic volcanic rocks above the massive sulphide horizon. Several drill holes have been completed through these lower mafic volcanic rocks and intersected a lower sequence of altered and stringer mineralized felsic volcanic rocks termed the Lower Felsic Block.

Southeast-northwest to east-west trending near vertical fault zones are evident in the Lemarchant deposit area. The strike-slip along these faults is poorly constrained; however evidence from drilling supports vertical and lateral displacements.

Mineralization

Volcanogenic massive sulphide (VMS) alteration zones are widespread in the Tally Pond volcanic belt. Large alteration zones have been identified at Lemarchant, Rogerson Lake, Bindon's Pond and Spencer’s Pond. Smaller areas of similar alteration are widespread throughout the volcanic units on the property, such as the Higher Levels Prospect.

Drilling at the Lemarchant deposit area has outlined a significant precious metal-rich copper-lead-zinc VMS deposit. To date, drilling has outlined significant semi-massive to massive sulphide mineralization between section 101+00N to 104+00N (the “Main Zone”; NI43-101 resource estimate), semi-massive to massive sulphide mineralization between section 105+50N and 106+50N (the “Northwest Zone”), and a massive sulphide drill intersection located at 400 metre depth on section 105+00N. The mineralization is characterized by high-grade, zinc-lead-copper semi-massive to massive sulphides with significant gold and silver contents and barite. Visible gold is observed in several drillholes.

The South Tally Pond property hosts numerous other underexplored VMS target areas including Bindon’s Pond, Rogerson Lake, Spencer’s Pond, Beaver Lake, Duck Pond West, and Gills Pond.
