Resource and exploration company Tyranna Resources has initiated a formal dispute process as a result of repeated claims allegedly made by emerging gold producer WPG Resources that part of exploration licence 5661, which surrounds South Australia’s Challenger gold mineral lease, does not form part of Tyranna’s operations. The ASX-listed company, a merger between Trafford Resources and Ironclad Mining, announced on Tuesday that it had initiated the dispute to protect its “leading ownership position” of the gold assets within the tenement immediately surrounding Challenger gold mine in the far north of South Australia.
