This was a partial inspection conducted by Janet Binns and Byron Walker of CDMG. The mine is
reclaimed and the permit has been revoked No facilities remain an site. No personnel are connected
with this mine site.
The focus of this arspection was fb foIIow up on the two slides noted in Division of Minerals and
Geology's May 11,1998 inspection. Mr. Walker assassed the sate in terms of engineering stability.
Mr. Walker's interoffice memo accompanies this report.
The slide West of Pit 4 did not appear to have enlarged since the May 11,1998 inspection. It appeared
that the ran out of the side had reached Grassy Creek, but had not blocked the creek. Grassy Creek
was Sowing unimpeded at the time of this inspection. the dimensions of the mndtlow are visually
estimated and paced at 40 R Wide by appn+wc. 120 R Long, with the toe of the slide spreading to ~ 90
R wide. Water ie flowing out ofthe slope ofthe slide at appmx Less than 3 gallons per minute.
Investigation of Pond 4 at the base of Pit 4 Ends the riser undercut and piping along riser to have
occurred. Fipung is not apparent on ontslope of embankment Jnet below the pond embankment on the
west side of the pond ontalope vegetation consists of very dense oak brush. 'Iltorongh investigation of
the slope below the pond is }mrited by the dense vegetation The head of the scarp below the pond was
accessed. Head scarp originates approx 70-90 R Below the pond embankment. Gmliying in elope
above the ecazp and bekrw the pond embaalanent was observed Slide head scarp is appmx 5 R in
heigjrt. A sediment delta apper+enfly from the run onY of the flexible pond riser sleeve has accnmuhrted
at this loc:atian. A spuing fi+om the hilWope ahro exln'bi>e itself here. Visually it appears that nahual
causes contabute to the formation of the slide, however, contnbutioa of concenhated water from Pond 4
may add to the instabr7ity of the slope.
Hairpin tmn on the acx;ess road to Pit 4 cartinnes 1p cut.
Piping of the ditch along access road to Pit 2/3 has occuaed. Riprap placement in the locale may
provide necessary reinforcement Spring down cutturg of access road 2/3 camtinues.
