Commencement of Drilling

 

 

Helix Exploration, the helium exploration and development company focused on
helium deposits within the 'Montana Helium Fairway', is pleased to announce
that, further to the announcement on 22 July 2024, drilling of the Clink #1
well on the Ingomar Dome project area in Montana has commenced.

 

Highlights

·    Commencement of drilling the Clink #1 well, to test the stacked
reservoir targets in the Amsden, Charles, Flathead Formations and fractured
pre-Cambrian basement.

·    Historic drilling has identified nitrogen-rich gas in Amsden, Charles
and Flathead formations that has never been assayed for helium.

·    Drilling will take 3-4 weeks to complete, followed by wireline
logging and extended flow tests.

·    First well in two-well Q3 drilling programme with the second well to
be drilled to appraise contingent helium resources at the Rudyard Project.

 

Bo Sears, CEO of Helix Exploration, said:

 

"We are delighted to commence drilling at the Clink #1 well on the crest of
the Ingomar Dome anticline.  Clink #1 will test stacked reservoir targets
with known gas identified in the Amsden, Charles and Flathead formations.
This well will allow us to fully appraise each target horizon with an extended
flow test. If successful, the Clink #1 well will be used as a future
production well, reducing time and cost to move towards first gas production
anticipated before the end of 2025.

 

"I'd like to express my gratitude to everyone involved in bringing the company
from IPO to drilling in less than 4 months. We look forward to keeping the
market informed and to delivering a safe and successful drilling campaign."

 

Background

Helix commenced drilling at Clink #1 well on the Ingomar Dome project in
Montana at approximately 10:00 MST on Sunday 11(th) August 2024.  Drilling is
expected to take 3-4 weeks followed by wireline logging and extended appraisal
flow tests.

Clink #1 primary target is the Flathead Formation at 7,410ft (2,260m) which is
the main horizon producing helium within the Montana helium fairway.
Secondary targets are the Amsden Formation at 3,840ft (1,170m) and Charles
Formation at 4,780ft (1,460m) where historic testing has flowed high nitrogen
gas to the surface, and which has not previously been tested for helium.  A
tertiary target exists in conceptual fractured basement plays in the
Pre-Cambrian from 7,750ft (2,360m) which was not drilled in historic
exploration. The Company will keep investors updated as drilling progresses
via RNS, potentially including updates on any significant helium gas shows
identified in drilling fluids by the on-site mass spectrometer during
drilling.

Post drilling, the Company will conduct open-hole logging to determine
petrophysical properties of the subsurface formations. This petrophysical work
can determine properties such as porosity, permeability, and the presence of
gas.

If results of the wireline logging are positive, the well will be cased and
cemented and prepared for testing.  Formation testing requires perforating
the casing in the target formations where gas can flow to surface and
production profiles can be determined via extended flow tests.  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.

An extended flow test will test pressure draw down and rebound over several
days will allow long term flow rates and depletion curves to be calculated and
proven reserves, if any, to be declared.

 

Ingomar Dome - Clink #1

Clink #1 well location is situated at the crest of the Ingomar Dome
approximately 200m to the west of the historic Hilliston #1 well.  The
Hilliston #1 well tested a 195ft column of non-flammable gas from the Amsden
Formation at high flow rate and minimal pressure loss over 30 days.  The gas
was tested at ~80% Nitrogen and was not assayed for helium, although a high
helium-in-soil gas anomaly measured at the wellhead suggests that helium gas
is present. Clink #1 has been designed to drill beyond the Amsden formation to
test stacked reservoir targets in the Flathead and Charles Formations.

The primary target is the Flathead formation which is the main regional
reservoir hosting helium production on the Montana helium fairway.  Gas is
known to occur in the Flathead formation having been identified in the
Treasure #18-1, located over 6 miles down-dip from the Clink #1 well location,
which logged 10-26ft of gas in clean sandstone but did not conduct a flow
test over the interval.

The secondary target is the Charles formation, a thick sequence of interbedded
limestone, dolomite, anhydrite and shale.  The Charles formation has
previously had gas identified in both the Froze #24-8 and Treasure #18-1
wells.  The Froze #24-8 well, located down dip at the southern end of the
Ingomar Dome, identified a total gas column of 175ft.  The Treasure #18-1
well, located over six miles down dip to the west of the Ingomar Dome,
identified a total gas column of 145ft.  Both wells tested high-nitrogen gas
(80.4%) similar in composition to gas tested from the Amsden formation but
were not assayed for helium.

 

Rudyard - Darwin #1

Rudyard Project consists of three stacked reservoir horizons within two
co-joined domed anticlinal structures underlain by the Great Fall Tectonic
Zone, a major structural zone which acts as the migration pathway for helium
released from ancient continental crust. Helium has been proven to occur in
stacked reservoirs at target depths between 5,000ft and 5,500ft (1,500m -
1,700m), being some 3,000ft shallower than target depth at Ingomar, with
associated cost savings in exploration and development.

Darwin #1 well is located on the northern dome, immediately to the east of a
640-acre section where helium has been proven in Drill Stem Tests ("DST") from
two historic wells.  These wells tested favourably for both grade and flow
rate, with helium tested at 0.9% from the Souris River formation and 1.3% from
the Ried River formation.  Darwin #1 will also test additional upside in the
previously untested Dry Creek formation.

Rudyard project has gross Contingent Helium Resources of approx. 484,000 Mcf
with additional gross Prospective Helium Resources of approx. 112,000 Mcf.
Drilling of an appraisal well with an associated extended flow test will allow
the Company to upgrade the Contingent Resources to Reserves.  Although
production rates seen on DSTs have been high, the production rate and pressure
decline has not been evaluated over an extended flow test. A confirmation of
these rates will move these contingent resources into the appropriate reserves
classifications.

 

The Directors of the Company are responsible for the release of this
announcement.

Helix Exploration is a helium exploration company focused on the exploration
and development of helium deposits within the 'Montana Helium Fairway'.
Founded by industry experts with extensive experience of helium systems in the
US, the Company's assets comprise of 52 leases over the Ingomar Dome; a large
closure of 16,512 acres with P50 unrisked gross prospective helium resource of
2.3Bcf and upside of 6.7Bcf. Historic drilling and/or testing has identified
gas in all target reservoir horizons.  The Company's second asset is 5,600
acres in Rudyard, Montana, where a helium discovery at up to 1.3%He has been
made within the closure from historic drilling adjacent to the leases.
Rudyard has P50 gross contingent helium resources of 482,000Mcf in two stacked
reservoirs with a further 112,000Mcf of gross prospective helium resource
within untested horizons.

 

Helix Exploration is focussed on drilling and early production at the Ingomar
Dome and Rudyard Projects.  An aggressive development timeline has seen
drilling commence in Q3 2024, with first helium production targeted for Q4
2025.  Helix is committed to open and transparent communication with
investors and the wider market as the project progresses through development.
