Midland Exploration Inc. in partnership with Osisko Mining Corporation announced the start of drilling program totaling 2,000 meters on the Dunn property. The program is designed to test several new gold targets identified during a recent frequency-domain induced polarization survey. The Dunn project is located about 35 kilometers northeast of Rouyn-Noranda in the Abitibi region of Quebec. From December 2009 to February 2010, a total of 108 kilometers of IP surveying, as well as a ground magnetic survey, were completed on a 156-kilometre grid. The IP survey largely focused on an 8-kilometre stretch along the Lac Caste Formation sediments, in order to detect porphyry-type gold mineralization similar to deposits in the Malartic and Duparquet areas, as well as Harker/Holloway-type gold-bearing structures associated with ultramafic volcanic rocks near the Destor-Porcupine Fault. This first drilling program on the Dunn project, totaling about 2,000 meters, is set to begin in the next few days and will test close to a dozen first-order targets. Osisko can earn 50% of Midlands interest in the property by spending a total of $1,300,000 in exploration work and making payments totalling $140,000 over a period of three years. The company must spend $320,000 in exploration work during the first year (firm commitment). Midland will be project operator until completion of a positive pre-feasibility study. Upon acquiring an initial 50% interest, Osisko will have the option to acquire an additional 15% interest, by delivering a bankable feasibility study, making annual cash payments of $40,000 and spending a minimum of $200,000 in exploration each year, up to the delivery of a bankable feasibility study within three years; or by solely assuming all exploration, development and mining operations on the Dunn property, earning 1% additional interest for each $1,000,000 invested on the property (up to 15% interest by spending $15,000,000).

Osisko Mining Corporation and Clifton Star Resources, Inc. are announced results from Clifton's 2009 drill program and extended core sampling program at the Duparquet Project located in the Abitibi region of Quebec. Drilling and extended sampling on selected holes were focused on three properties: Beattie, Donchester (eastern extension of Beattie) and Duquesne. Previous drilling and sampling by Clifton had focused on higher-grade veins or tabular breccias/shear zones located mostly within syenite porphyry intrusions. Current sampling and future drilling will focus on delineating broader zones of mineralization that may be amenable to large scale open-pit mining. Highlights from 37 drill holes reported herein include 171.1 metres averaging 1.62 g/t Au (D09-01B), 99.5 metres averaging 1.29 g/t Au (B09-72) and 119.4 metres averaging 1.50 g/t Au (B09-92). For the 2010 season, Osisko has outlined a 120,000 metres drill program for the Duparquet project, which will consist of 100,000 metres definition program on Beattie-Donchester, as well as 20,000 definition program on Duquesne. The objective of the former program will be to define a bulk tonnage inferred resource by early 2011 on the mineralized Beattie-Donchester syenite porphyry complex. Four drills are presently mobilized and drilling commenced on both properties on February 15.

Osisko Mining Corporation expected to Report Q1 2010 Results on April 22, 2010. This event was calculated by Capital IQ (Created on February 16, 2010).
