The purpose of the MR is <br />to provide for two angle boreholes ( LW-16-05B and LW-16-05C) to be located at the existing GVB-16- <br />05 gob vent borehole site and two angle boreholes ( LW-16-07B and LW-16-07C) to be located at the <br />existing GVB-16-07 gob vent borehole site <br />The purpose of the four boreholes are to enhance the drainage of methane by attempting to intercept <br />linear geologic joint or fracture features expected to occur in the GVB LW-16-05 borehole and the GV13- <br />LW-16-07 borehole vicinities. These NE/SW trending joint features, when encountered so far in gate <br />road development, has resulted in exceptional inflows of methane gas. <br />We are also including an updated page 6 of Exhibit 2.04-E3, Geologic Information, Item 9 - Methane <br />Drainage Well Information. An updated Map 2.05-M1, Sheet 6 of 6, General Facilities Gobvent <br />Boreholes will be forthcoming. <br />Please contact me at (970) 929-5806 should you have questions or require further information. <br />Sincerely, <br />Jmes A.
