However, the firm said that during the 12 month period 14,918 ounces of gold was produced and sold during commissioning of the mine at an average price of CAD$1,650, generating revenue of $25.2m.
Ming Mine revenues were credited to the Mineral Properties asset and would continue to be until commercial production is declared, Rambler said.
It added that following the completion of construction and commissioning of its copper concentrator, revenue of $3m was realised from the sale of 1,271 tonnes of concentrate in July.
George Ogilvie, President and Chief Executive Rambler Metals & Mining said: "Commencing and accelerating production at our Ming Copper-Gold Mine has been a great achievement for the company this year".
"Generating revenue and a consistent focus on reducing cash costs has given us a strong balance sheet which will further support organic growth and acquisitions," he said.
