Amarillo Commissions Initial 43-101 Resource Estimate on the Butia Prospect, Southern Brazil
May 18 2010 - 8:37AM
Marketwired Canada
Amarillo Gold Corp. (TSX VENTURE:AGC) ("Amarillo" or the "Company") is pleased
to announce that it has awarded to Atticus Consulting SAC (Atticus) of Lima
Peru, the task of conducting the first resource estimate on the Butia prospect,
the most advanced of the numerous prospects that fall within the Lavras do Sul
project.
The resource estimate will be NI 43-101 compliant and Tony Amberg (Sociedad
Cartografica Limitada, Chile) will be the qualified person compiling the
estimate. Mr. Amberg is a geologist of 24 years experience based out of
Santiago, Chile. He is a graduate geologist, BSc (Honors) of London Imperial
College and he also has a MSc. in Geographical and Geodetic information systems
from London University and has extensive international and Latin American
experience, particularly in gold. Mr. Amberg is currently visiting the property
as part of the 43-101 due diligence process. Simon Mortimer, geologist and the
principal of Atticus, will construct the geological model using the Leapfrog 3-D
geological software. Atticus plan to complete the report prior to the end of
June. The following sections provide a brief summary of the prospect.
Location and Access: The Butia prospect is located 4km west of the village of
Lavras do Sol (pop. 8000), in the state of Rio Grande do Sul and is accessible
by regional highway from Porto Alegre, the state capital. The prospect is
located on unimproved land grazed by cattle.
Tenure: In October 2006 Amarillo entered an option agreement with Rio Tinto PLC,
after an open competitive bid. The Butia prospect is included in this option
agreement. Amarillo has met the prerequisites of the agreement to date. Future
obligations to Rio Tinto include:
1. A $US880,000 payment on the formation of a Joint Venture with the
underlying owners. Payment is triggered by the transfer of title to that
JV.
2. A $US 1,000,000 payment to Rio Tinto within 90 days of completion of a
bankable feasibility study.
3. A $6.50/oz cash payment for every one million ounces of recoverable gold
reserves under Amarillo's control.
4. Rio Tinto has a back-in right to acquire 70% of Amarillo's interest in
the property by paying Amarillo three times their expenditure in the
event that Amarillo's equity interest contains in excess of 7 million
ounces of recoverable gold.
To gain tenure Rio Tinto had an option agreement with various mineral right
owners in the area. Amarillo has taken over the Rio Tinto position within this
underlying option agreement. The terms of this option have been met and Amarillo
is in the process of implementing a formal joint venture agreements with the
various mineral right owners. These agreements will also consider that the
Lavras do Sul project lies within the border area.
The Butia prospect lies on exploration permits 810096 and 810095 both owned by
Mineracao Carmec Ltda, (Carmec). Amarillo has secured a binding letter of intent
from the owners that provides for:
a. Agreement on the general terms of the 60% Amarillo, 40% Carmec, Joint
Venture.
b. Carmec will dilute and not contribute.
c. Agreement on the dilution formula
d. Once Carmec dilutes to 10% their interest converts to a 1.5% royalty.
Geology: The Butia prospect is hosted within the neo-Proterozoic Lavras do Sul
granitic complex. This complex is 10km by 10km in area and consists of a
monzonite/granodiorite core surrounded by a rim of perthitic granite. Gold
mineralization is hosted within the granitic complex and within the surrounding
Hilario volcanics to the east. The mineralization varies from east, where it is
hosted in discrete veins systems with a Cu-Ag-Au-W-As association, to west where
the gold mineralization is hosted in broad alteration zones with a Pb-Au-Ag
association. The presence of micro-crystalline silica and the clay mineralogy
(illite, phengite) indicates that the mineralization is epithermal in nature.
The Butia prospect occurs near the western boundary of the intrusive complex
within the perthitic granite. The Butia alteration zone strikes E-W for 1.7km
and is 500m wide as mapped by the presence of green sericite and hematite. The
Butia prospect occurs in the western 500m of this alteration zone. The gold
mineralization zone at Butia as defined by the current drilling is associated
with intense alkali alteration that forms an episyenite microbreccia. The gold
mineralization forms an "L" shape at surface controlled by an E-W structure 250m
long and a N-S structure 250m long. The mineralization, which outcrops at
surface, attains its greatest extent at a depth of 70m-90m below surface and
then decreases in area at depth.
History: The Lavras do Sul area has been the focus of gold rush style
exploitation since it was discovered in the 1780's, with a peak of activity from
1901 to the 1930's. It is not known how much gold was extracted from the Butia
area. Much of the soil over the area of alteration has been overturned and
worked in the past. In the 1930's British and Belgian companies worked the area
with hydraulic mining. The larger workings, of which there are several,
typically exceed 50m by 100m in area. There are also numerous small tunnels and
adits associated with the workings. In the 1980's CBC (a Brazilian state mining
company) drilled 1500m in 11 holes at Butia.
In 2005 Rio Tinto completed 891m of drilling in 5 holes at Butia.
Density: Amarillo has taken 192 densities readings using the displacement
method from 5 separate drill holes at Butia. The mean value of all rock types is
2.65 g/cc. The mineralized episynite (S.G. 2.68 cc/g) is slightly more dense
than the unmineralized perthitic granite (S.G. 2.61 g/cc).
Drill Results: Amarillo has completed 11km of drilling in 45 holes at Butia at
the time of this release. The drill is still operating on the prospect on widely
spaced step-out drill holes. If these holes successfully locate further gold
mineralization, this data will be incorporated into an updated resource estimate
at a later date. Table 1, appended to this news release, records the composite
gold assay results for each hole drilled by Amarillo using a 0.3 g/t cut-off
while Table 2 provides the locations and orientation of the drill holes.
Comment: Amarillo looks forward to generating the first 43-101 resource estimate
from its most advanced prospect within the Lavras do Sul project. However, it is
important to recognize that this is only the initial estimate from this project.
After completing the Butia step-out holes referred to above, the drill will
begin resource definition drilling at the Cerrito prospect. This will allow an
updated Lavras resource estimate that includes Cerrito in four to six months
time. There are 19 separate prospects within the Lavras do Sul project
represented by areas of old gold workings, it is the company's intent to drill
test each one systematically. The company will update the Lavras do Sul resource
estimate each time the work warrants. Amarillo's expectation is that one day
there will be a centralized plant treating gold ores from a number of the more
significant prospects within the Lavras do Sul complex.

ABOUT AMARILLO:
Amarillo Gold Corp. is a company focused on the acquisition, definition and
discovery of gold resources in Brazil. Its principal projects are the Mara Rosa
project in the state of Goias and the Lavras do Sul project in the state of Rio
Grande do Sul. The Posse Deposit at Mara Rosa was found by an independent 43-101
compliant preliminary economic assessment study carried out by CCIC to contain
643,000 ounces indicated from 13.5MTonnes @ 1.48 g/t Au, 538,000 ounces inferred
from 13.0MTonnes @ 1.26 g/t Au at a 0.5g/t cut-off grade and the project is in
the economic evaluation stage. The Posse deposit is located in an area of
excellent infrastructure located some 35 km NE of Yamana's Chapada open pit
Cu-Au operation, 105 km NE of Serra Grande's underground Au mine, 105 km NNW of
Anglo American's nickel laterite project (in construction), 95 km NW of
Votarintim's Niquelandia nickel laterite mine and approximately 60 kms NE of
Yamana's Pilar Au project (in feasibility). Grid power to the site was
established during the previous open pit mining operation and the Serra da Mesa
hydro-electric dam lies 35 km to the east.
The Lavras do Sul project is in the advanced exploration stage with over 15,000m
of drilling with encouraging gold mineralization being discovered and defined,
also in an area of excellent infrastructure. The Company also has a portfolio of
earlier stage projects. All properties under Amarillo's management are located
in areas of good infrastructure and robust community support.
