Ms. Mochizuki has 6 years of experience in geology and environmental
consulting. Most recently she has lead hydrology field activities and data
acquisition at FMG’s North Star Site in the Pilbara as it transitions from
an exploration camp to a working mine site. Bore logging, documenting
water flow rates supervising and directing well installation, monitoring
groundwater production and conducting pump tests, she has secured
dependable water sources through out the site for drinking water,
construction and mine production activities under the supervision of the
senior hydrogeologist. Marisa recently conducted water exploration
activities in the Canning Basin that will ultimately supply water for mine
production and slurry transportation for phase two of the mining
operation. She then returned to North Star and is currently leading further
local water exploration as the minesite’s demands evolve. In addition
she has had significant exposure to the RC and Diamond sampling and
logging with their exploration team.
During her residence with AECOM, she provided assistance and
expertise with regards to mapping and core logging for drilling
operations, groundwater and LNAPL investigation and monitoring, well
and soil vapor probe installation and destruction, data acquisition and
analysis. This work included subcontractor supervision, regional and
local permitting, task managing, soil, water, LNAPL and vapor sampling,
hazard identification, and reporting for various facilities in theLong Beach
area and an emergency response to an oil spill in Michigan.
The drilling methods she has employed include air rotary, mud rotary,
hollow stem auger, sonic, direct push, dual rotary and reverse circulation
drilling, conventional and diamond.
The groundwater and core samplingmethods she has employed include
peristaltic, dedicated bladder, portable and dedicated electric pumps,
disposable bailers, Simulprobe®, and discrete interval samplers.
Prior to employment with AECOM, Ms Mochizuki acquired experience
working as an Environmental Educator with Westminster Woods and
participating in a geochemistry internship at the Hawaii Volcano
Observatory (HVO) after obtaining her Bachelors Degree in Geology
from the University of California, Berkeley. Ms Mochizuki is fluent in
Spanish and currently working towards expanding her technical
knowledge and experience.

November 2013- Present
Hydrology Project, North Star, Pilbara. As the North Star exploration

2. camp transitions to a fully operating mine site, water demands have
drastically increases for construction purposes, personnel daily use and
eventually ore production. In order to meet these demands Marisa is
currently directly supervising and or performing all field operations for the
drilling, logging, and designing of observation and water productionwells
at FMG’s North Star site under thesupervisionof senior hydrogeologist
Richard Martin. Employing air rotary, mud rotary, dual rotary and reverse
circulation drilling methods while documenting v-notch data and chip
logging she designs observation wells tailored to specific site capabilities
and testing preferences. She has performed pump tests and recorded
data during drilling activities in order to estimate feasibility and location of
future production well installation and collected ground water samples for
laboratory analyses in order to assess the location’s suitability as a
purpose specific water supply. As drilling resources fluctuate she has
supervised and directed multiple, simultaneous drilling operations and
coordinated with earthworks to ensure that preparations for future drill
sites have been properly made in order to eliminate driller stand-by time
and facilitate work progress. Sheconducts health and safety analyses
and monitors health and safety parameters during job activities including
the acquisition of site and job specific permits as required. During down
time she frequents theexploration drilling sites learning as much as
possible about thelocal formations from her colleagues and gaining
experience on diamond core and RC logging. Once water targets were
met on site she began water exploration activities in the remote Canning
Basin employing mud rotary drilling and soil logging in order to
investigate its suitability as a potential water source for future, large scale
operations. Plans changed back at North Star and water demands more
than doubled requiring an urgent return for further drilling and water
sourcing.
