A major lead-zinc ore exploration project that straddles the Yukon-Northwest Territories boundary has been moving ahead on the Yukon side but still awaits final regulatory approval on the N.W.T. side.

Selwyn Resources is exploring an area in Howard's Pass, near Tulita, N.W.T. — a tract of land that has been described as one of the largest undeveloped lead-zinc deposits in the world.

The deposit straddles the boundary between N.W.T. and the Yukon.

Selwyn said when it decided to explore the size of the ore deposit the company needed to obtain an environmental assessment, provide a land use plan and get permits from both sides of the boundary.

In the Yukon, that took 90 days. In the Northwest Territories it has taken 2½ years just to get the environmental assessment, which was just completed.

Company spokesman Justin Himmelright said that means they've pushed ahead to spend $50 million exploring the Yukon side of the deposit.

"Essentially it means that none of the investment we've been making in the project has been going into the Northwest Territories. It's been focused exclusively in the Yukon to this point."

In the Yukon, Selwyn set up two 50-person camps and the firm has been busy drilling test holes for a couple of years.

Larry Wallace, chair of the N.W.T. Sahtu Land and Water Board, said Selwyn wants to explore a conservation area that may one day become part of the expanded Nahanni National Park. As a result, Wallace said, people in the Sahtu region have a land claim, and they have the right to take a closer look at the mining project. If that means the process takes longer on the N.W.T. side, then that's the way it is.

"There were projects going on where people didn't have a say," Wallace noted. "They really didn't know exactly what was going on. Now they do. And that happens under the new regime."

Wallace said that when all local concerns are addressed, the Sahtu will be happy to start issuing permits.

Selwyn, meantime, still needs to find a partner with deep enough pockets to build a mine, regardless of which side of the border it's on.
