PERTH, AUSTRALIA, 20th September, 2012: Cleveland Mining Company Ltd. (ASX: CDG) is proud to announce that it has started mining at the Premier Gold Mine.

Ore is now being stockpiled at the plant, where live commissioning is underway.

The final external barrier to the start of mining and processing was overcome when the electrical connection to site was established after a longer-than- anticipated bureaucratic process. The Company has now received all permissions required to start round-the-clock mining and processing of ore through the Stage 1 gravity circuit.

Managing Director of Cleveland Mining, Mr David Mendelawitz, said that the

Company was delighted to have reached this milestone.

"We are debt free, about to generate cash-flow, and have built the first stage of the mine far quicker than is typical. With gold now trading at around $1750 per ounce, $200 per ounce higher than 6 months ago, it's a great time to start selling it," said Mr Mendelawitz.

"Our strategy aimed to build a reasonably small mine first so we could understand what affects budgets and schedules when building mines in Brazil, recruit and structure our teams optimally, and not expose the Company to restrictive debt burdens."

"When we expand Premier and build other larger mines, we will be well positioned to get them right. The commencement of mining, along with the lessons learned to date, put us in a very strong position to create a solid future for Cleveland Mining."

"We are now working to get Stage Two, the cyanide circuit, of the Premier mine built as quickly as possible, whilst at the same time working to increase our gold resources through exploration or acquisitions. Work also continues to schedule in Amapá state on our Iron projects, where we are currently sinking shafts for bulk samples for metallurgical testwork."

About Cleveland Mining

Cleveland Mining is an Australian-managed, publicly-listed minerals company, squarely focused on developing projects to owner-operate. Cleveland has three distinct project hubs:
1) The Crixás Hub, Goiás State, central Brazil. Projects: The Premier Gold Mine JV, O Capitão, Baú, Guarinhos, Pantera - Gold-focused

Iron ore-focused

Cleveland recently formed a strategic alliance with fellow-ASX listed company, BC Iron (ASX:BCI) aimed at acquiring and co-developing new iron ore projects in Brazil.
Cleveland has a different approach to project selection, with project economics driving target selection. Geological prospects, local costs and infrastructure are rigorously scrutinised before entering into a project. Projects are chosen according to their potential to generate returns at the bottom of the economic cycle, with Cleveland only operating in areas backed by legislation and government that can provide stable and transparent operating environments.
