BOART LONGYEAR LIMITED SCHEME MEETING

As you may be aware, the Directors of Boart Longyear Limited (the Company or Boart Longyear) have announced a proposal to redomicile the Company from Australia to Canada by way of Scheme of Arrangement (the Re-domiciliation).

On 26 October 2018, the Federal Court of Australia made orders for the Company to convene a meeting (the Scheme Meeting) of holders of fully paid ordinary shares in the Company (Shareholders) to consider the Re-domiciliation. To view a copy of the Scheme Booklet outlining details of the Re-domiciliation (which includes the Notice of Scheme Meeting), please see the documents below.

Under the Re-domiciliation, if implemented, Boart Longyear Incorporated (Boart Longyear 'Canada') will acquire all the ordinary shares in the Company. Boart Longyear 'Canada' will apply to be listed on the ASX and the Company will be delisted from the ASX. Boart Longyear 'Canada' will effectively replace the Company as the listed entity on the ASX.

The Scheme Meeting will be held at 11.00am (Adelaide time) on Thursday 6 December 2018 at the Adelaide Convention Centre, Riverbank Room 1, North Terrace, Adelaide South Australia 5000 Australia.

You should read the Scheme Booklet carefully in its entirety, including information on the advantages, disadvantages and risks of the Re-domiciliation (as set out in Section 5 of the Scheme Booklet) before deciding whether or not to vote in favour of the Scheme Resolution.

The Boart Longyear Directors consider that the advantages significantly outweigh the disadvantages and risks. Therefore, the Boart Longyear Board unanimously recommends that you approve the Re-domiciliation and vote FOR the Scheme Resolution at the Scheme Meeting.

The Independent Expert, Grant Thornton, has concluded that the Re-domiciliation is in the best interests of Boart Longyear's shareholders.
