Amarillo Gold Corp. (TSX VENTURE: AGC) ("Amarillo" or the
"Company") is pleased to announce that it has received an updated
gold resource calculation for its 100%-owned Posse deposit on the
Mara Rosa gold project in Goias State, Brazil. The new gold
resource estimate includes the most recent 31 drill holes completed
during an 8524 metre definition drilling program. The results are
given in Table 1 below and are NI 43-101 compliant.

The independent qualified person for the resource estimate
report is Hugo Hoogvliet, a consulting geologist with 25 years
experience and a member of the AIG. The resource calculation was
completed by Keith Whitehouse a geologist with 30 years experience
and a principal of Australian Exploration Field Services Pty Ltd.
("AEFS"). Mr. Whitehouse is a member of the Aus.IMM and a CP
(Chartered Professional Geologist).
The modeling process consisted of completing four runs through
the data for each of the zones modeled (Hanging Wall, Main, and
Foot Wall) using different size search ellipsoids. The different
ellipsoids were initially used to differentiate and assign resource
classification codes to each resource block (i.e. Measured,
Indicated, Inferred and Not Classified). This process was then
refined based on the drill-hole data density. The resource was
modeled using two different modeling algorithms - Inverse Distance
Squared and Median Indicator Kriging. A second run with modified
search parameters to specifically model the higher grade portions
of the deposit was completed and combined with the model from the
first run. This combined resource model improved the fit to the raw
data. The estimates were made using Micromine software.
Buddy Doyle, CEO and President of Amarillo commented, "We are
very pleased with these results. The definition drilling has
materially improved the quality of the gold resource at Posse.
Prior to definition drilling the indicated resource was 60% of the
global resource; now it is more than 90% (M+I), and the gold grade
has also improved over past estimates. The Measured and Indicated
category resources will now be used as the basis for the pit
design, scheduling, and the economic modeling for the ongoing
Pre-feasibility Study, which is on track for completion early next
quarter."
The qualified person for this report as per the NI 43-101
guidelines is Kevin R. Kivi, PGeo (APGO).

About Amarillo Gold Corp.
Amarillo Gold Corp. is focused on the acquisition, discovery,
and definition of gold resources in Brazil. The Company's 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 contains 1,174,900 ounces of gold measured and
indicated from 20.85 MT at 1.75 g/t Au, and 156,400 ounces of gold
inferred from 3.63 MT at 1.38 g/t Au (0.5 g/t cut-off grade) (NI
43-101 compliant resource as independently determined by Australian
Exploration Field Services Pty. AEFS). The Mara Rosa Gold Project
is in the Pre-feasibility stage.
The Posse Deposit was successfully mined by Western Mining
Company (WMC) during the 1990s (mined areas are excluded from the
above-stated resource figures), and is located in an area of
excellent infrastructure approximately 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 Ni laterite project (in
construction), 95 km NW of Votarintim's Niquelandia Ni laterite
mine, and some 60 km NE of Yamana's Pilar Au project (in
Feasibility). Grid power to the site was established during WMC's
open pit mining operation, and the Serra da Mesa (450 MW)
hydro-electric dam lies 35 km to the east.
The Lavras do Sul Project is an advanced exploration stage
property (190 sq km) comprised of more than 19 prospects centered
on historic gold workings, with encouraging gold mineralization
discovered and defined by more than 16,000 metres of drilling. The
initial resource estimate at the Butia prospect reported 215,000
ounces of gold indicated from 6.4 MT at 1.05 g/t Au, and 308,000
ounces of gold inferred from 12.9 MT at 0.74 g/t Au ((0.3 g/t
cut-off grade)(NI 43-101 compliant resource as independently
determined by Atticus Consulting 2010). Lavras do Sul is also
located near excellent infrastructure. The Company also has a
portfolio of earlier stage projects and all properties under
Amarillo's management are located in areas of good infrastructure
and mining-friendly communities.
