1. Greetings Mining investments of Korea has been limited to simple financial investment or purchasing mining products. Recently, with the strong support of Korean government for securing energy resources, financial investors as well as strategic investors in Korea begin to aggressively seek potential development projects and participate in international big mining projects. Accordingly, as the resource development’s vitamin, mining services business in Korea including evaluation, exploration and drilling, field operation are now in desperate need for investors and in the process of going international. In response to this business climate, Drilling Services International Corp.(DSI) was established in September 2011 as the nation’s first drilling services company in mining and geothermal area. DSI is invested by Hanjin D&B(HDB) with the expectation of the business bringing in a financial gain for all backers. Hanjin D&B(HDB) is a world famous innovative drill rig manufacturer in Korea. Based on the 25 yrs’ experience and knowledge, HDB is world’s third-ranked company in sales of drilling rig by exporting hundreds of drilling rigs and equipments per year over the world. Particularly, HDB is the world best company in the area of water hammer and RC drilling machine. HDB performed 35,000 m drilling of uranium mine in Mongolia(under the order of COGE GOBI, AREVA, France) in 2007. In 2009, HDB carried out directional drilling with total length of 1,400m for Korea Hydro & Nuclear Power Co., Ltd. HDB has received many patents for global drilling equipment manufacturing related technologies, such as Water hammer drilling, Large-diameter(10 inch) core drilling, directional drilling, and Sonic drilling, etc. Although DSI is a small start-up now, we promise that we provide competitive services in a near future with the core advantages created by combining manufacturing capability of HDB and services experience and investors connection of EHG.

Starting from the exploration drilling services for Rapu-Rapu copper mining operated by LG Corp. in Philippines, DSI provide gold mine drilling service for PT T.M.E in Bengkulu, Indonesia(2013). Also, we are drilling CBM(CoalBed Methane) exploration, operation drilling service in Kapuas, Indonesia(2013). DSI will provide various services for domestic investors with the highest quality and technology. In the future, throughout continuous acquisition, equity investment and joint venture with small and medium sized local drilling companies in global resources rich countries including Australia, Canada, South America and Asia, DSI will try to its best to become world’s third big mining service company within a few years to come. DSI will also do its best to secure nation’s resources through enhancing international competitiveness in the area of mining drilling services in Korea. Sincerely March 2015
