The Company provides two types of drilling services to mining companies through its 116 drills and approximately 500 employees: underground drilling and surface drilling. The Company’s scope of operations and highly qualified workforce allow it to offer its customers specialized drilling services adapted for complex situations and rugged territory, with approximately 60% of the Company’s revenue for the twelve months ended March 31, 2008 (on a pro forma basis) generated from specialized drilling operations. The ability of the Company to offer specialized drilling has resulted in a more stable client and revenue base for the Company as alternate providers are not as readily available or adequately skilled. Management believes the Company is the largest underground drilling company in Canada (based upon the number of drills in operation) and has a significant and growing market presence in surface drilling in Canada and internationally. The Company services major mining companies such as Goldcorp Inc. and Xstrata plc, as well as intermediate mining companies such as Agnico-Eagle Mines Limited, FNX Mining Company Inc., IAMGold Corporation and Northgate Minerals Corporation and junior mining companies such as Alexis Minerals Corporation and V irginia Mines Inc. Underground drilling is typically undertaken at the production stage where it is required to delineate deposits and to assist the mine operator to identify where production efforts should be focused. The Company derived approximately $41.3 million (54%) of revenue from underground drilling for the twelve months ended March 31, 2008 (on a pro forma basis). The Company’s Canadian operations are located in Qu ? ebec and Ontario. The Company has recently aggressively expanded its international operations and currently has drills operating in the United States, Mexico and South America. R evenue was approximately $20.9 million for the domestic surface drilling division and approximately $9.2 million for the international surface drilling division for the twelve months ended March 31, 2008 (on a pro forma basis). Growth in each of these areas was driven both by organic growth and acquisitions. 28
