Amarillo Provides Update on Mara Rosa Exploration Drill Testing Commences, Goias State Brazil

VANCOUVER, BRITISH COLUMBIA ("Amarillo" or the "Company") has
commenced exploration drilling on its Mara Rosa project in Goias
state, Brazil. The drill will initially target two prospects
developed over 2007. One is called Lambari the other is named Grid
A.
The Lambari prospect lies 3km to the east of the Posse Deposit.
Interest in the area was first derived from anomalous gold results
(700 ppb Au) in BLEG (bulk leach extractable gold) sampling in the
streams and from the occurrence of several garimpo's that were
worked up to the early 1990's. Subsequently the company has
completed geological mapping and took 2,200 soil samples covering a
grid of 20 sq. km. This work highlighted four linear trends 50 to
150m wide up to 1.5km long of anomalous gold in the soils. Five
trenches where completed in to the soil anomalies and cumulatively
they measured 1.4 kilometers long. Thirty-six auger holes where
completed near the Joao Lemos garimpo. The trenching revealed grab
values of up to 7.0 g/t with channel samples carrying 12m of 0.78
g/t Au with 3.3m of 2.2 g/t Au hosted in a quartz sericite schist
with qtz veins stringers. The quartz sercite schists are part of a
metavolcanic, sedimentary package that dips steeply (55 degrees to
80 degrees) to the west, striking ENE. The drilling will test for
down dip mineralization beneath these trenches and soil
anomalies.
The Grid A prospect lies 5km South of Posse and was recognized
by previous workers in the area but has never been adequately
tested. The area is noticeable as an anomaly in the K-channel
airborne radiometrics, and is produced by very mica rich quartz
sericite chlorite schists. These schists have veinlets containing
fuchsite (high chrome vanadium mica) and have elevated copper and
gold in the soil. They dip to the west at a relatively shallow 15
to 30 degrees with a hanging wall of fine grained diorite and
schists and a foot wall of amphibolites and schist. This signature
not dissimilar to the setting at the Posse deposit, with the added
interest that the entire volcano sedimentary package changes strike
from ENE to NE on a hinge beneath grid A. The exploration model is
that this is a splay off of the thrust fault that hosts Posse and
that the structural setting is favorable. The company has taken 600
termite mound samples, covering 2.5 sq km, 160 soil samples
covering 1 sq km, completed 8 trenched totaling 1.85 kilometres
from which 2535 channel samples where taken. A total of 36 auger
holes where also completed. From the trenches results such as 66m
of 0.21 g/t gold, 19m of 0.4g/t gold, 0.5m @ 1.71 g/t gold and 2m @
0.59 g/t have been returned. The drilling is designed to test the
down dip extension of the values in the trenches.
Both the Lambari and Grid A prospects lie near the edge of the
exhumed (by erosion) paleo-laterite surface at Mara Rosa and have
deep saprolite profiles. (saprolite is a leached tropical soil).
The drilling will test the fresh rock beneath this weathered
horizon. Each prospect will receive four test holes, from which the
results will be awaited before proceeding with further testing.
After this first round of exploration drilling the drill will be
moved to the Posse Deposit to begin delineation drilling and
exploration drilling for nearby extensions to this deposit.
Amarillo Gold land package in the Mara Rosa district consists of
over 60,000 hectares of exploration permits and 3 mining
concessions over the Posse pits and infrastructure areas from the
previous mining operation. The Posse Deposit was found by an
independent 43-101 compliant preliminary economic assessment study
carried out by CCIC to contain an indicated resource of 643,000
ounces @ 1.48 g/t Au plus an inferred resource of 538,000 ounces @
1.26 g/t Au.
