Successful Re-Entry of Clink #1

Helix Exploration, the helium exploration and development company focused on helium deposits within the 'Montana Helium Fairway', is pleased to provide an operational update on the Clink #1 well at the Ingomar Dome Project.

Highlights

·    Successful control of Mowry formation to 2,622ft (800m) by setting 7- inch intermediate casing through entire interval.

·    Successful re-entry and deepening of wellbore to 8,550 ft (2606m).

·    Company will now complete the well with production casing and commence testing.

·    If multiple formations are deemed suitable for testing, each zone will be tested independently from the bottom-up to allow for isolated tests over each interval.

Bo Sears, CEO of Helix Exploration, said:

"The successful re-entry and subsequent deepening of Clink #1 is a significant milestone for the Company.  I am delighted with the re-entry efforts and the exceptional work of our engineering team, as we see promising results in each of the target formations."

Background

Re-entry operations commenced on Clink #1 with an initial goal of placing the problematic Mowry shale formation behind pipe.  The Mowry was successfully cased over the entire interval with 7-inch casing cemented to surface.

Following successful re-entry to 8,030 ft and with the well in good condition, the Company deepened the Clink #1 to 8,550 ft to determine if the Precambrian could be reached.  Precambrian rock was not found but a second thick Cambrian sandstone horizon was found at 8,290 ft all the way to total depth.

The Company will now complete the well with production casing and commence testing.  Production casing will be run in the hole to total depth and cemented to surface.  Testing will proceed after cement on casing is dry.
