ASX Release By e-lodgement

Drilling Contract Signed for the Bluebell VMS Project

Highlights

• Drilling contract signed with leading provider of drilling services in the USA

• Initial 5,000m RC drilling program to test “open pit” exploration target

• Follow up drilling of the recently reported high grade surface intersection

• Drill rig expected to be on-site in late January

Australian-American Mining Corporation Limited (“AusAmerican” or “the Company”) (ASX: AIW, OTCQX: OZAMY) is pleased to announce that the Company has signed a drilling contract with National EWP, a leading provider of drilling services in the USA, for the Bluebell copper-gold-silver project in Arizona.

The initial 5,000m RC drilling program at Bluebell will focus on testing the “open pit” exploration target, with holes targeting the top 200m of the mineralised system. A number of holes will also be targeting the down dip extension of the recently reported high grade surface intersection of 38m @ 1.2% copper, 0.5g/t gold and 22.9g/t silver (ASX announcement dated 14[th] November, 2012).

The company has received all necessary permits to begin drill pad preparation and it is expected that the drill rig will be on site in late January.

AusAmerican managing director Richard Holmes said:

“This is an exciting time for the company as it prepares for the maiden drilling program on the Bluebell project. The recent high grade surface intersection has reinforced the concept that the old timers “high graded” the underground mine and the drilling will be focussed on defining the mineralised stock work”.

Sincerely,

Richard Holmes Managing Director
