The developers say it will be an all-year-round complex

Councillors in June refused to extend exclusive rights to the disused Glyn Rhonwy quarry at Llanberis to the firm which wants to build on the site.

But the consortium, Snowdonia Gateway, said after meeting officials it was confident plans would achieve the council's "vision for the site".

It now aims to submit evidence to back up its plan within eight months.

Gwynedd Council last month said it was not for or against the scheme but was willing to talk to other developers.

It said it believed "significant changes" to the initial proposal affected its ability to achieve the council's economic vision for the site.

Gwynedd first agreed to a six-month period of exclusivity for the firm in February 2004. That was followed by a six-month extension in October 2004, and another for three months earlier this year.

'Robust submission'

At the time, Snowdonia Gateway said it was "extremely disappointed, frustrated and bewildered" this had not been extended further.

But after an "open" and "constructive" meeting, the consortium of six local business people said it understood the council's legal constraints.

Managing Director Gwyn Pritchard said: "Our objectives meet and exceed the issues that Gwynedd needs desperately to resolve, so as to create economic growth and to turn the tide of young people leaving Wales."

The project would cost �115m in the first phase and include indoor skiing, a water park and hotel. The company said there would be 550 jobs in the first instance, and �12m a year for the local economy.
