Mining in Peru's northern district of Pataz will be suspended for 30 days, President Dina Boluarte said on Monday, after 13 gold mine workers in the area were kidnapped and killed by illegal miners.

Violence in Pataz has been contained in the past, mitigating risk to the broader industry. Still, greater scrutiny is needed across the entire production chain as skyrocketing gold prices create a further incentive for illegal activities, according to BTG Pactual analyst Cesar Perez-Novoa, who specializes in natural resources.

The men were killed in a region that has seen growing conflict over access to ore in recent years. The mine has also been a hotbed of illegal gold mining.
