Comparing an operational mine, like BRAZIL'S well known mine, 43-101 to that owned by SRSR, if that tells us all, its marginal: An historical resource for the REO was previously estimated by Jair Carvalho (geologist), an Extramil employee and is contained in a report filed with the DNPM on November 30, 1989. MBAC has received the digital excel spreadsheets utilized in the historical resource estimation. Extramil undertook an estimate based on 11 cross sections 40m apart with half distance influence. The cross sections were defined based on the above mentioned auger drilling, pitting and 16 of the 32 diamond drill holes. The estimate was then collated into an excel database with the half distance weighted average used to determine the average grade and tonnage.
Extramil reported, based on partial exploration of the property, 1.3 million tonnes at an average grade of 9.62% REO (using a 6% REO cut-off and density of 2.0 tonnes/m3). The 9.62% REO grade was comprised of the following:
Mr. Beau Nicholls, the qualified person responsible for the technical disclosure in this press release information, has not done sufficient work to verify or classify the historical estimate as current mineral resources or mineral reserves; and MBAC is not treating the historical estimate as a current NI 43-101 mineral resource or mineral reserve. The qualified person is not able to relate the classification parameters used by Extramil to the NI 43-101 parameters of measured, indicated and inferred and no recent estimates are available. Accordingly, the historical estimate should not be relied upon.
To enable a current NI 43-101 mineral resource estimate to be completed and to verify the historical estimate by Extramil, the qualified person has recommended that MBAC undertake due diligence umpire sampling of 10% of the mineralized historical drill samples that are available along with undertaking a detailed topography and drill hole collar survey and bulk density sampling.
The following table contains significant results of historical diamond drilling on the Project. :
The FS diamond drill holes (HQ and NQ diameter) were drilled in 2008 and are located in the central portion of the REO anomaly and are approximately 80m apart from each other.
The BAR diamond drill holes (NW diameter) were drilled in 2004. BAR-05 is located 700m east of the FS holes and BAR-01 is 370m SE of the FS holes.
