Leigh Creek Energy Limited (ASX: LCK) (“LCK” or “the Company”) is pleased to announce that it has received approval of the first of the three Activity Notifications (AN) required to commence its Pre-Commercial Demonstration (PCD) stage of the Leigh Creek Energy Project (LCEP).

Managing Director’s comments

Commenting on the announcement, LCK Managing Director Phil Staveley said: “Following approval of the first AN, LCK can now commence on site construction activities. This is a monumental moment for the Company as it moves towards its objective of being a key provider of energy in Australia.”

Activity Notification process

Following approval of the Statement of Environmental Objectives (SEO) for the LCEP PCD on 19 April 2018, the Company submitted the AN submissions to the Regulator for approval.

AN’s are required to advise the Regulator of the specific activities that will be undertaken under the framework of the SEO. The ANs submitted are for the following activities:

1. PCD Aboveground plant construction (APPROVED);

1. PCD Process well drilling; and

2. PCD Operations including operating, decommissioning and monitoring.

LCK and its contractors are scheduled to commence on site assembly and commissioning of PCD modules and supporting services and equipment next week. This is expected to take approximately 8 weeks. During this stage of the PCD, personnel will be in a range of accommodation in Leigh Creek and Copley, and at the on-site camp that will exist for the brief construction period.

In conjunction with this activity, three process wells will be drilled to service the underground ISG chamber, on approval of the PCD Process well drilling AN. This activity is projected to last for 25 days.
