The owners of an Oregon goldmine have called in gun-toting right-wing militiamen amid a bitter land use dispute with the U.S. government. Tensions have remained high at the Sugar Pine Mine near Medford after the facility was served with a federal stop-work order. The owners summoned  armed guards from the conservative Oath Keepers activist network ahead of a major protest outside local offices of the Bureau of Land Management yesterday.

Co-owner Rick Barclay acted after receiving a stop-work order last month when officials said they found equipment on site indicating operations inconsistent with standard mine development requirements. The miners have since appealed the order and spokesman, Kerby Jackson, confirmed paperwork had been filed to keep officials from 'burning or breaking anything' on the property - but gave no more details. The owners insist they want to avoid a high profile stand-off while BLM officials say they want to resolve the dispute peacefully.

Protest: Joseph Rice of the Oath Keepers (R) holds a copy of the U.S. Constitution while speaking alongside Sugar Pine Mine owners George Backes (L) and Rick Barclay (C) At issue is a dispute over mine ownership records, Oregon BLM spokesman Jim Whittington said. The owners argue they have exclusive surface rights and need not follow federal regulations. But Whittington said while the owners have mining rights, the surface rights were ceded to the BLM in 1961 by the then-owners. The miners say they want to avoid a standoff like last year's fight between Nevada rancher Cliven Bundy and the federal government in which the BLM sought to seize cattle because Bundy refused to pay grazing fees. Federal agents ultimately backed down. Gear: An Oath Keeper is seen with a vest that reads 'US Patriot' on Wednesday .
