04:45 PM EDT, 07/31/2026 (MT Newswires) -- Questerre Energy ( QTEYF ) said Friday that its PX Energy oil shale processing facility in southern Brazil has been temporarily shut down following a critical pipe failure in the furnace that supplies heat to the main processing plant.

The company said operations personnel initiated the shutdown to prevent further damage to equipment. No injuries were reported and the main processing facility was not damaged.

Questerre expects the shutdown to last about three to four weeks, during which the facility will remain offline, resulting in lost production and revenue. The company estimates the direct cost of the corrective work at about C$1.5 million.
