Rambler North is an underground operation and is part of the Ming Mine, owned and operated by FireFly Metals Ltd. Rambler North is located in Newfoundland and Labrador, Canada, approximately 20 kilometers east of Baie Verte.

Exploration in the area of the Rambler property dates back to the early 1900s with the discovery of auriferous sulfide mineralization. The polymetallic sulfide deposits in the Ming Mine area are known to contain copper, zinc and minor lead, gold and silver along with traces of other metals. Mineralization in the deposits has been classified in the past as either massive sulfide, footwall stringer, or disseminated ore.
