2 Notes Regarding Sample Protocol QA/QC: The sample chain of custody is managed by the Buckreef Gold geology team on site. Reported results are from diamond drilled core samples. Intervals of core to be analyzed are split into half using a mechanized core cutter, with one half sent to the Laboratory for geochemical analysis and the remaining half kept in storage for future reference and uses. Diamond drilled core has been HQ size and recoveries are consistently 100% across all drill hole intercepts reported.

Sampling and analytical procedures are subject to a comprehensive quality assurance and quality control program. The QA/QC program involves insertion of duplicate samples, blanks and certified reference materials in the sample stream. Gold analyses were performed by standard fire assaying protocols using a 50-gram charge with atomic absorption (AAS) finish and a gravimetric finish performed for assays greater than 10 grams per tonne.

Sample Preparation and analysis were performed by independent SGS Laboratory in Mwanza, Tanzania. SGS Laboratory is ISO17025 accredited and employs a Laboratory Information Management System for sample tracking, quality control and reporting.

The results summarized in this MD&A from the “Buckreef Main Zone NEE” prospect is an extension of the known Buckreef Main Zone. The intercepts confirm a continuity of over 200 m of known Buckreef main deposit to the Northeast. The intersections reported here are a down-hole length and may not represent true width, however the true width is estimated to be between 50% - 60% of the length.

The results summarized in this MD&A from the “Stamford Bridge” target show intercepts that confirm an interpreted mineralized shear zone trending 070 degrees (ENE) that is over a km long. The intersections reported only covers the first 100 m strike length, they are a down-hole length and may not represent true width, however the true width is estimated to be between 50% - 60% of the length.

3 Notes Regarding Sample Protocol from Metallurgical Variability Test Results: A 1 kg aliquot of each of Composite 3 to Composite 14 at a crush size of 100% - 1.18 mm were blended to form the master composite. The master composite was split into 1 kg aliquots using a rotary splitter. Three 1 kg aliquots from the master composite were milled in a rod mill to target grinds of 80% - 53 µm, 80% - 38 µm and 80% -25 µm. A 200 g aliquot was split from the 80% - 53 µm and wet milled in a ceramic charged ball mill to a target grind of 80% - 5 µm. The grinds were checked by screening the milled material on the specific screens and weighing the oversize material. A 20 g aliquot of the 80% - 5 µm was submitted to an external laboratory for particle size distribution. One 500 g aliquot of the milled sample was submitted for the head chemical analysis.
