In July 1950, two Canadian mining companies, Frosbisher Limited and Ventures Limited, formed a joint venture, named Kilembe Mines Limited (KML), whose objective was to mine copper from under the Rwenzori Mountains near Kasese. KML built and operated a copper smelter in Jinja and maintained offices in Kampala, the country's capital. Other assets include a housing estate for staff in Kasese and the 5MW Mubuku I Power Station in the Rwenzori Mountains.
