EXPLORATION ’99 – RARE METAL EXPLORATION ROUNDUP — Avalon updates Big Whopper

Avalon Ventures (AVL-V) has updated a prefeasibility study of its wholly owned Big Whopper petalite (lithium silicate) deposit, north of Kenora, Ont.

The company now expects that market demand for its petalite can be met by processing less ore and that all of the petalite produced can be marketed as a high-grade product averaging 4.41% Li2O with a low iron content.

On a pretax basis, the project will likely yield a rate-of-return of 39.5%, and the net present value is estimated to be $53.5 million at an 8% discount rate. These estimates are based on a debt-to-equity ratio of 75-to-25, with the payback period projected at 3.2 years.

This improvement in profitability is partly due to a smaller, more-efficient plant design that has reduced estimated capital costs by 30% to $29.8 million.

Avalon proposes annual petalite production beginning at 17,000 tonnes and increasing to more than 32,000 tonnes in the fifth year.

Bulk-sampling in combination with a full feasibility will begin this winter.
