Adyabo project Mato Bula work program
The Mato Bula infill diamond drill program was concluded on May 15, 2017. A total of 7,025 metres in 49 holes were completed. Geophysical induced polarization survey work continues on-site and is expected to be completed in early June, 2017. The most recent drill results received are outlined in the associated table.

(2) No top cut has been used on analyses.
(3) Intervals use a 0.3-gram-per-tonne gold cut-off value.

Quality control
The planning, execution and monitoring of East Africa's drilling and quality control programs at the Harvest and Adyabo projects have been conducted under the supervision of Jeff Heidema, PGeo, East Africa's vice-president, exploration. Mr. Heidema is a qualified person as defined by National Instrument 43-101, and has reviewed and approved the geological information contained in this news release. Diamond drilling was co-ordinated by East Africa's contract geologists who also managed the preparation, logging and sampling of core and rock samples, in addition to carrying out bulk density measurements. During sampling, quality control standards and blanks were introduced at predetermined intervals to monitor laboratory performance. A system of field, reject and pulp sample duplicates was also incorporated, as were specific programs of reassaying and umpire lab assaying to both monitor laboratory performance and also characterize potential mineralization, all consistent with industry best practice.
Drill core samples have undergone preliminary preparation at the Bureau Veritas Mineral Laboratories facility in Ankara, Turkey, and are crushed to 80 per cent passing 10 mesh, and pulverized to 85 per cent passing 200 mesh (PRP70-1KG package). Analyses are conducted at both the Turkey facility and the Bureau Veritas Mineral Laboratories in Vancouver, Canada, with diamond drill core analyses utilizing aqua regia digestion and ICP-ES (inductively coupled plasma emission spectroscopy) for base metal and silver analyses (AQ370 package), and infill sample program utilizing aqua regia digestion and ICP-MS/ICP-ES (inductively coupled plasma mass spectrometry/inductively coupled plasma emissions spectroscopy) (AQ270 package) for base metal and silver analyses. Gold analyses are conducted at the Turkey Bureau Veritas Mineral Laboratories facility via fire assay fusion with AA (atomic absorption) finish, and gravimetric analyses are completed for overlimit samples (FA430, FA530-Au packages).
