Diamond Drilling is Scheduled to Commence Thereafter. Osisko is Currently Planning on Spending Approximately $750,000 on Adanac for the First Year of Exploration. the Target is a Low Grade, Bulk Tonnage Gold Deposit. Geology and Alteration Mineralogy at Adanac Are Similar to What has Been Observed at Canadian Malartic.

About the Adanac Property 

The Adanac Project is Located on a Southern Splay of the Famous Cadillac Larder Lake Break That is Host to an Impressive Number of Historical and Current Mines That Collectively Produced Almost 100 Million Onces of Gold. the Area has Been Gaining Significant Attention With the Recent Exploration Success of Gold Bullion Development Corp on Their Flagship Granada Project, Which Lies Immediately Adjacent to the Adanac Property Along the Western Claim Boundary. the Adanac Property Consists in 91 Claims Covering 3276 Hectares and is Underlain by Pontiac and Temiscaming Metasedimentary Rocks That have Been Strongly Deformed and Sheared. an Unknown Quantity of Gold has Historically Been Produced on the Property Mostly from the Adanac Shaft That Reaches a Depth of 98 Metres Opening on 3 Sublevels. Threegold Began Exploring the Project Through Property-Scale Geochemical and Geophysical Surveys Between 2007 and 2009 Followed by a 4,474-Metre, 22-Hole Diamond Drilling Program Carried Out in the Fall of 2009 to Investigate the Most Significant Targets on the Project. This Program Helped Outline a 1.8-Kilometre Gold Trend on the Project.

About the Standard Gold Property

The Standard Gold (Duverny) Property Includes the Past-Producing Standard Gold Mine. the Standard Gold Mine Operated Intermittently Between 1935 and 1953, Producing an Unknown Quantity of Gold. the Mineralization is Contained Within a Diorite Sill Trending Southeast With a Width Ranging Between 150 Metres to 200 Metres. the Sill has Been Traced Through Its Geophysical Signature Over a Distance of Three Kilometres and Will Be a High Priority Exploration Target. the Historical Resource of the Standard Gold Mine is Estimated at 132,750 Tonnes Grading 5.43 Grams Per Tonne Gold.

Threegold has Not Verified the Classification of This Resource Under National Instrument 43-101 and Therefore the Above-Quoted Figures Are Reported as an Unclassified Historical Resource Estimate. Resource Estimates Prepared Under Reporting Codes Other Than National Instrument 43-101 Should Not Be Relied Upon to Conform to Current Standards and Definitions. Furthermore, Readers Are Cautioned That Mineral Resources Are Not Economic Mineral Reserves and That the Economic Viability of Resources has Not Been Demonstrated. Historical Unclassified Resources Are Considered Too Geologically Speculative to have Any Economic Considerations Applied to Them. it Cannot Be Assumed That All or Any Part of a Historical Mineral Resource Will Ever Be Upgraded to a Higher Ni43-101 Category.

Victor Goncalves, President and Ceo Reports: "We Are Pleased to have Developed This Unique Relationship With Osisko. it Will Allow Us to Continue Searching for Key Projects Knowing That We have All the Expertise and Know-How to Bring the Projects to Fruition."
