November 2004 Monthly Report
Deaz Mr. Waldron:
The following summarizes monitoring and site activities at the Battle Mountain Resources Inc.
(BMRI), San Luis Project for the month of November 2004.
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 29i6, no water was present for
sampling and subsequent analysis.
Depths to water were collected for the tailing impoundment main embankment piezometers on
November 29th, the West Pit and tailings embankment monitoring wells were collected on
November 30'6. The November 29th tailing impoundment piezometer measurements identified
these installations were either dry or contained less than 12 inches of water as illustrated in Table
2. Tables I 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 29th. The November tailings pond underdrain flow average was 38.41 gpm and a total
of 390 gallons of water was excavated from the leak detection system yielding a monthly average
of 12.188 gpad.
During November, the West Pit water treatment plant operated efficiently dischazging a total of
8,8 ] 8,200 gallons (27.06 acre-feet) of water to Rito Seco Creek and a total of 1,004,000 gallons
(3.08 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
precipitation accumulation for October was .63" inches, with the largest accumulation occurring
on November 10"' (.34").
