"), to review the historic resource on the Mara Rosa property, and has let a minimum 1000m drilling contract to Blackhawk Drilling to drill test the priority targets generated by this work.

The Mara Rosa property (area 24,600ha) is located near the village of Mara Rosa, in the Goias state of Brazil, about 3 hrs by vehicle north of Goiania, the state capital. Contained within this property is the Posse POSSE. This word is used substantively to signify a possibility. For example, such a thing is in posse, that is, such a thing may possibly be; when the thing is in being, the phrase to express it is, in esse. (q.v.)  deposit where previous workers defined a historic gold resource. Exploration potential on the surrounding ground held by Amarillo is also considered good, containing previously uninvestigated artesianal workings and untested geochemical and geophysical ge·o·phys·ics

SAMSA is a multinational independent geological and mining consulting group based in Santiago, Chile Santiago, officially Santiago de Chile (Spanish: ), is the capital of Chile, and the center of its largest conurbation (Greater Santiago). . Their task is to review the upper 100m of the Posse deposit with regard to a possible economic, open pit opportunity. Amarillo management have also instructed SAMSA to look at the potential extensions of any higher grade zones and then recommend optimum drill hole locations for testing the continuity of these zones.

Once this "high grade" open pittable review is completed SAMSA will review the historic resource at the Posse deposit and bring it to 43-101 standards.

The Mara Rosa Project, is the subject of an independent technical report (the "Technical Report") prepared by B. Terrence Hennessey, of Micon International Limited, in December, 2003. The Technical Report was prepared in accordance Accordance is Bible Study Software for Macintosh developed by OakTree Software, Inc.[]

, but review the historic resource was outside its scope.

In 1997, Metallica Brazil estimated a mineral resource for the Posse south lode within the Mara Rosa Project which was not compliant with National Instrument 43-101, section 2.4 since it was prepared prior to the implementation of this National Instrument. This historical estimate was made after re-logging approximately 8,100m of core and remapping exposures in the pit.

In this instance a similar resource estimate of 15.47 million tonnes @ 1.47 g/t containing 730,342 ozs of gold using a 1 g/t cutoff was reported. The similarity of Barrick's due diligence estimate and the estimate by Metallica Brasil suggests that there is a noteworthy gold accumulation on the Property.

The Barrick and Metallica Brazil historic resource estimates were to 400m depth. Amarillo has requested a study of the top 100m as the upper part of the deposit will be key if any economic exploitation is to occur. SAMSA have been instructed not to cut the assays to 10g/t in the upper zone and to review the possibility of continuous zones of relatively higher grades than the globe grade estimate of the historic reserve at shallow depths. SAMSA will recommend drill holes to check for continuity and improve the confidence of resource estimates if this work determines it is warranted.

One example of a continuous zone of higher grade gold values occurs along sections 100,100m to 100,350m (local grid, 250m in length) at about 40 to 70m below surface in a relatively flat zone about 50m wide as shown by the selected assays from drill holes in this zone in the historic database.

As well as defining and enhancing by drill testing possible open pittable zones within the known mineralization, Amarillo would also like to grow the project by exploration success.

The main focus of the exploration work will be to enhance the economics of the property by:

This anomaly is coincides with the trace of the same geological structure as the Posse deposit and has only been previously tested with four drill holes. Amarillo considers that there is good potential for further gold mineralisation along this structure/anomaly.

2. Approximately 150 to 200m to the South East of the Posse Gold deposit there is an untested gold in soil anomaly. The cause of this anomaly has never been satisfactorily explained.
