KIRKLAND LAKE, ONTARIO--(Marketwire - July 15, 2009) - Kirkland Lake Gold Inc. (TSX:KGI)(AIM:KGI) (the "Company") is pleased to present its year-end (April 30, 2009) gold reserve and resource estimates for its operations in Kirkland Lake, Ontario on both the historic Main Break and the recently discovered South Mine Complex or SMC. The South Mine Complex consists of 15 or more mineralized zones, five of which have been defined over strike lengths in excess of 1,000 feet.

During the fiscal 2009, the Company concentrated its exploration efforts on the SMC and realized substantial increases in proven and probable reserves as well as measured and indicated resources. These increases are attributable to drifting, definition diamond drilling as well as exploration diamond drilling from both the 5000 and 5300 level cross cuts and the decision to focus drilling resources on upgrading ounces from the inferred category in anticipation of increased future gold production.

"The geology department delivered a 28% increase in proven and probable ounces in the SMC and a 28% increase in measured and inferred resources, despite not having access during the fiscal year to certain drill bays due to the ventilation project," said Company President, Brian Hinchcliffe. "An increase in development projects this year will allow for greater flexibility and will enable more strategic exploration."
