(Reuters) - Thousands of Romanians protested on Saturday against plans by U.S. energy group Chevron to explore for shale gas in a poor eastern region and a Canadian company's project to set up Europe's biggest open cast gold mine in a Carpathian town.
Plans by the leftist government of Prime Minister Victor Ponta to approve the tapping of natural resources in the European Union's second-poorest state have triggered nationwide protests since the start of September, throwing together local communities, environmentalists, civic rights groups and the clergy.
While the two projects are separate and in different stages of development, protesters have criticized a lack of transparency in approving both. They demand stronger safeguards to protect Romania's environment and national heritage.
On Thursday, Chevron suspended work on what was to be its first exploration well in the small town of Pungesti in Vaslui county, 340 km (210 miles) northeast of the capital Bucharest, after locals blocked access to the site.
But the people of Pungesti, most of whom live off subsistence farming in one of Europe's poorest regions, have continued protesting, asking officials to revoke drilling plans.
On Saturday, more than 800 locals, priests and activists gathered in front of the empty lot where Chevron plans to install the well. Hundreds rallied in other cities.
In punishing windy weather, they waved "Stop Chevron" banners and knelt to the ground while a priest led them in prayer. A group of horse riders clad in national costumes then destroyed a cardboard model of an oil well.
Shale gas faces opposition due to concerns around hydraulic fracturing or fracking, the process of injecting water and chemicals at high pressure into underground rock formations to push out gas.
Critics say it can pollute water supplies and trigger small earthquakes. Advocates say it has a strong safety record and point to countries like the United States, where extensive fracking has driven down prices.
"I am against shale gas exploitation because of the chemicals used in fracking," said Vasile Ciobanu, 25, who has returned to Pungesti after working abroad for three years and now lives a few hundred meters away from the proposed well site.
"I don't think the company and Romanian officials are thinking about what could happen to people who live here."
Chevron declined to comment. Earlier this year, the company won all necessary approvals to drill exploratory wells in Vaslui, while it also has rights to explore three blocks near the Black Sea. The exploration phase would last for about five years.
The U.S. Energy Information Administration estimates that Romania could potentially recover 51 trillion cubic feet of shale gas, which would cover domestic demand for more than a century and help push prices lower.
In the central Romanian town of Campeni, around 2,000 people protested against Canada's Gabriel Resources plans to use cyanide to mine 314 metric tons of gold and 1,500 metric tons of silver in the small town of Rosia Montana.
The state also holds a minority stake in the mine. The government approved a bill to speed up the project, which has been waiting for approval for 14 years. In Rosia Montana, many argue the mine is the only solution to create jobs.
But one of the bill's provisions grants the mine "national interest" status, which would make it easier for the company to force the few locals who oppose the plan to quit their land, in return for compensation. Critics say this is unconstitutional. The bill is now following a tortuous path through parliament, and it is unclear when a vote will take place.
