Investigation into Continued Damage at the Solitario Ranch Page 3 1 1 1 evident about the time of the court trial, spring 1997. Some of the leaks were repaired in 2000 but have since reoccurred. During the investigation into the cause of the first incidence of damage to the house certain features were noted and photographed along the railroad tracks to the south of the Tatum house. The ties were pulling away from the ballast only in the area over the 1N Section. This was clearly an indication of movement along this section of track. Calculations were made concerning the stability of the mine pillars sitting on a soft mud floor, and the "punching" of these pillars into the floox2 Reports and Memos by Pioneer Engineering Pioneer Engineering has investigated the problems and failure of the Tatum house beginning in December of 1994.

The developers concern was potential subsidence and the effects on the ground water from the Basin Resources' Golden Eagle Mine and the lack of cooperation with the mine's management. This included the indiscriminate construction of drill access roads This dispute was partially resolved by blocking the renewal of the mines' mining permit until certain provisions, already legally required, were restated in the permit and certain other conditions or stipulations were included in the permit approval. Basin personnel and the Project Manager for Rancho Escondido, Rich Babnick, discussed visible subsidence cracks. This included concerns for the developments' water line, which crossed the subsidence area. Quite a lot of other information on the mine was obtained during this investigation. z Worksheets included in the appendix, Appendix 4 s Appendix 2
