Deaz Mc Waldron:
The following summarizes monitoring and site activities at the Battle Mountain Resources Inc.

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 May 31", no water was present for sampling
and subsequent analysis.
Depths to water were collected for the tailing impoundment main embankment piezometers on
May 31", the West Pit and tailings embankment monitoring wells were collected on May 31".
May 31" tailing impoundment piezometer measurements identified these installations were either
dry or contained less than 12 inches of water as illustrated in Table 2. Tables l 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 underdmin flow was pumped intermittently during the
month to minimize the collection pond level. The leak detection system was measured on May
31~`. The May tailings pond underdrain flow average was 34.89 gpm and a total of 680 gallons of
water was excavated from the leak detection system yielding a monthly average of 20 gpad.
During May, the West Pit water treatment plant operated efficiently discharging a total of
10,577,400 gallons (32.46 acre-feet) of water to Rito Seco Creek and a total of 687,600 gallons
(2.11 acre-feet) of water was transferred from the water treatment plant to the tailings
