FREDERICTON -- A group of protesters say the New Brunswick government's proposed new regulations for shale gas exploration aren't enough to make the industry safe.

About a dozen people marched in front of a government building in Fredericton today to show their opposition to measures announced earlier this year.

Spokeswoman Julia Linke says the government's consultation process is lacking because it doesn't ask for the consent of New Brunswickers.

The group is particularly concerned with hydraulic fracturing, or fracking, to extract gas from shale deposits.

Fracking involves blasting a mixture of water, sand and chemicals into a well bore to split the surrounding rock and release trapped pockets of natural gas.

Opponents say fracking puts groundwater supplies at risk.

The government released a discussion paper in May containing 116 recommendations that addresses a number of issues including well design, royalties and protection of water supplies.
