November 2005 Monthly Report
Dear Mr. Sorensen:
p~C 13
The following summarizes monitoring and site activities at the Battle Mountain Resources Inc.
(BMRI), San Luis Project for the month of November 2005.
Surface and ground water monitoring and analysis were completed for all required sites during
the month per the terms and conditions of the TR-32 Quality Assurance and Quality Control
(QA/QC) plan.
Vacuum on the tailing lysimeters was verified on November 30"', no water was present for
sampling and subsequent analysis.
Depths to water were collected for the tailing impoundment main embankment piezometers and
the West Pit and tailings embankment monitoring wells were collected on Novemebr 30`".
November tailing impoundment piezometer measurements identified these installations were
either dry or contained less than ]2 inches of water as illustrated in Table 2. Tables 1 and 2
below identify the depth to water measurements collected for each of the site monitoring wells,
piezometers and lysimeters as required by the terms and conditions of the TR-32 QA/QC plan.
The tailing impoundment collection pond underdrain flow was pumped intermittently during the
month to minimize the collection pond level. The leak detection system was measured on
November 30t°. The November tailings pond underdrain flow average was 27.10 gpm and a total
of 700 gallons of water was excavated from the leak detection system yielding a monthly average
of 20 gpad.
During November, the West Pit water treatment plant operated efficiently discharging a total of
9,015,200 gallons (27.67 acre-feet) of water to Rito Seco Creek and a total of 925,900 gallons
(2.84 acre-feet) of water was transferred from the water treatment plant to the tailings
impoundment. Seepage along Rito Seco Creek remained dry during the month. The monthly
