Oil discovery in Turaco -1 C7 formation

The Company is pleased to announce that the Turaco 1 well has tested
oil in the upper section of the C7 formation.

The Turaco-1 well has been finalized and logs from selected sections
of the C7 Formation, tested to measure the petrophysical properties.
The well proved oil in the upper section of the C7 Formation (5742 –
5746 ft MD). Tests will continue with slickline, to determine the size
of the oil accumulation to evaluate commerciality and further
development. The lower section C7 (5915 – 5919 ft MD), produced 100%
water.

Mobilisation to Vikingo Well

SLS (the farm in partner for the drilling campaign) is now “rigging
down” in Altair to mobilize the equipment to LLA-47 – the Vikingo well.
Estimated mobilisation time is 12 days.

Julio Cesar Garzon, VP of Exploration, commented: “We are pleased with
the confirmation of oil tested in the upper part of the C7 formation.
IOX and SLS are looking forward to the next phase of the drilling
campaign with the wells planned in the LLA-47 license.”
