Trevali Mining Corporation

At Trevali, we are asking ourselves some big questions about what it means to be a global mining company in today’s world.

We know that modern society needs mineral resources and the products that mining helps create.

As times change, society’s expectations of us change too.

Expectations about environmental responsibility.

Around what it means to be a good corporate citizen.

About being a company that is sustainable for the long-term.

And one that benefits its employees, its communities and its shareholders.

At Trevali, we are excited by these evolving expectations. They inspire innovative ideas and create new opportunities for us to enhance how our business operates.

Motivated by the potential that these questions present, we are focused on constant, incremental improvements in our business. Bringing creativity, agility and innovation into the very heart of the company. Operating efficiently and with the highest of safety standards. We are working to make ongoing improvements that contribute to achieving larger long-term goals.

By asking, and answering, these questions, we will create a different kind of mining company, and a new Trevali.

We embark on this journey with the key ingredients for success: strong assets, potential for resource expansion, a great balance sheet, and an engaged team of professionals.

As a reflection of our new vision, we are also launching a new corporate identity.

We are just getting started. Watch this space.

Ruttan

Location

Ruttan is a copper-zinc massive sulphide deposit located approximately 21 km east of the village of Leaf Rapids, which in turn is approximately 750 km north-northwest of Winnipeg, Manitoba, Canada. The property is accessible by all weather roads.

History

Discovered in 1968, the Ruttan Mine operated from 1973 to 2002 and historic production has been reported to be approximately 55 million tonnes grading 1.23% copper (Cu) and 1.41% zinc (Zn).

Property Agreement

Trevali (and predecessor Kria Resources) completed an option to acquire 100% of Ruttan and Bill 5025 claims subject to a combined 4% NSR royalty (2% NSRs held by two separate parties).

Acquisition terms included combined cash payments of $780,000 (paid) and 200,000 shares of Kria (issued). The work commitment on the property has been satisfied.

Half of each 2% NSR royalty can be purchased back by Trevali after payments of $2 million and $1.5 million respectively.

Geology

Ruttan is a bimodal-siliciclastic type of volcanogenic massive sulphide deposit (VMS) similar to those found in the Iberian Pyrite Best of Portugal and Spain and in the Bathurst district of New Brunswick.

Ruttan is a relatively large VMS deposit when compared to others types of these deposits found throughout the world (see table below).

Technical Report

An initial NI 43-101 compliant mineral resource estimate for the Ruttan Project was completed by Tetra Tech Wardrop in February 2008, which was subsequently updated in September 2008 to incorporate drill hole and assay data from the 2007/2008 exploration programs that targeted both the West Anomaly and Hanging Wall Zinc Zone (HW Zinc). The new estimate is based on 4,875 holes totalling 577,263 metres, which includes an additional 30 holes and 9,123 metres compared to the previous resource estimate.

The Inferred Mineral Resource at the Ruttan Deposit is estimated to be 19.75 million tonnes grading 1.17% copper and 1.47% zinc using a 1.0% capped copper equivalent cut-off grade. (Please review Disclaimer)

Property Potential*

Two drilling programs have been conducted since acquiring the Ruttan property: one in the summer of 2007 that consisted of 9 holes totalling 2,421 metres and a second in the fall/winter of 2007/08 that consisted of 23 holes totalling 6,594 metres (please see Kria press releases dated October 30, 2007, January 10, 2008 and June 10, 2008 for complete assay results).

The Ruttan property has good exploration potential. Priorities for future potential exploration include the following:

  • An airborne VTEM survey was conducted on the Ruttan and Bill Claims in 2008 and there are a number of targets to follow up on.
  • The upper section of the West Anomaly near surface (west of the old open pit) holds potential for additional discoveries.
  • The area to the east of the Main Mine remains open and requires additional drilling.
  • The deposit remains open to depth. Sparse drilling shows the continuation of the mineralized horizon.
  • A mineralized horizon located approximately 80 metres to the footwall of the West Anomaly is sparsely drilled.
  • The DAR 2 zone (Bill 5025 Claims) located 12 km south of the Ruttan Mine represents additional potential at a shallow depth. The zone has a strike length of 250 metres, a depth of 250 metres and a thickness of 2 to 10 metres.
  • A detailed review of historical data should be conducted to determine the potential for further exploration opportunities within the property.

*Where Trevali discusses exploration/expansion potential, any potential quantity and grade is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
