TriAusMin Restates Current Woodlawn Underground Mineral Resource to Comply With JORC 2012 Edition


TriAusMin Restates Current Woodlawn Underground Mineral Resource to Comply With JORC 2012 Edition

Aurora, Ontario CANADA, January 29, 2014 /FSC/ – TriAusMin Limited (TOR – TSX), (“TriAusMin” or the “Company”) is pleased to announce that the existing global Woodlawn Underground Mineral Resource (previously reported in 2006 according to the 2004 Edition of JORC Code and subsequently presented in a report prepared in accordance with Canadian National Instrument 43-101 and filed on has been reviewed and restated according to the 2012 Edition of the JORC Code by an independent Resource Consultant who is also a “qualified person” under Canadian National Instrument 43-101. The independent report is entitled “Woodlawn Underground Project – JORC (2012 Edition) Mineral Resource Restatement at December 2013″. The report was authored by Mr Robin Rankin (MSc DIC MAusIMM (CP)) for independent geological consultancy GeoRes. The restatement includes a Code Table 1 and that has been included at the end of this release. There has been no increase or decrease in the stated Resource.

The Consultant’s report included details on all Resource relevant project information and data derived during the period 2006 – 2013. It was concluded that none of the additional information would make a material change to the previously reported Resources. He specifically addressed exploration drilling at Woodlawn undertaken during the period, principally 2010-2013, commenting that the new data “was not at sufficient density or close enough to existing lens intercepts to reliably allow correlations and thus warrant inclusion with existing data and re-estimation of Resources”. He believes however that the drilling results, which contain lens grade mineralisation, are positive and that further nearby and in-fill drilling will confirm correlations and thus significant extensions to existing or new lenses. The Consultant’s view on re-estimation took into account that TriAusMin had already reviewed the new data through reporting of JORC Exploration Target figures in 2013.

The Woodlawn Underground Mineral Resource is now considered to be 2012 JORC compliant. For the purposes of compliance with Canadian National Instrument 43-101 requirements concerning use of codes (foreign codes) other than the “CIM Definition Standards – for Mineral Resources and Mineral Reserves” in technical reports on mineral projects, the JORC mineral resource categorization used for the Woodlawn Underground Mineral Resource is directly equivalent to the CIM categorization.

TriAusMin’s CEO Mr. Wayne Taylor commented –

“We are very pleased to be able to restate the Woodlawn Underground Resource to the 2012 Edition of the JORC Code. The restatement has provided an opportunity to review the previous work and validate this against the new standard. We also remain very confident about the potential from the recent drilling success, including the discovery of the new high-grade Kate lens, to make material additions to the existing Resource base at Woodlawn and importantly, in an area immediately adjacent to the existing underground mine workings. This resource base, along with the new mineralisation, is expected to lead to the reopening of the Woodlawn Mine and for TriAusMin to establish itself as a profitable producing mining company in the near term.”

The JORC (2012 Edition) classified Woodlawn Underground global Mineral Resources are tabulated below.

Woodlawn Project Background

The Woodlawn Project is centred on the former Woodlawn Mine located 30 kilometres south of Goulburn and 200 kilometres southwest of Sydney, where the company holds two significant poly-metallic resource-based assets; the Woodlawn Underground Project (“WUP”) and the Woodlawn Tailings Retreatment Project (“WRP”).

When in production (1978 to 1998), the Woodlawn open pit and underground mine produced approximately 13.4 million tonnes of high grade zinc, lead and copper ore from a number of separate, fault-bounded massive sulfide zones mined to a maximum depth of 630 metres below surface (only selected lenses were mined to this level). A Measured and Indicated Resource 1(a) of 8.6 million tonnes grading 10.28% Zn, 4.00% Pb, 1.8% Cu, 84 g/t Ag and 0.5 g/t Au as well as 1.5 million tonnes of Inferred Resources 1(a) at an average grade of 9.6% Zn, 4.1% Pb, 1.7% Cu, 87 g/t Ag and 0.6 g/t Au previously released by the Company exist within and around the former operations.

The WUP involves the evaluation of re-establishing underground mining at Woodlawn. The high grade nature of this deposit and the demonstrated potential to re-establish mining operations makes this a high priority project for TriAusMin. Drilling in 2012 and 2013 confirmed the capacity to add resources down dip to the previously mined ore lenses.

The WRP is expected to process approximately 11 million tonnes of tailings produced by the former Woodlawn Mine. Processing will produce separate zinc, copper and lead concentrates that contain by-product silver and gold. The WRP’s planned production rate as a standalone project is approximately 1.5 million tonnes per annum with an expected mine life of approximately 7.5 years. All metallurgical test work, engineering studies and financial modelling have been completed with the business case confirming a low-risk mining and processing project with strong economics at long term projected metal prices. A feasibility study on the WRP was prepared in accordance with National Instrument 43-101 in 2009 and is filed on

The WRP and WUP Projects are both attractive on a standalone basis, however, the co-development of the projects provides significant capital cost benefits, higher production rates and optimal operating flexibility as well as providing enhanced overall economics and a higher return on invested capital for shareholders.
