THOR MINING PLC

CDI SALE FACILITY FOR HOLDINGS OF LESS THAN A MARKETABLE PARCEL ON ASX

Thor Mining Plc ("Thor" or the "Company)" is pleased to announce a CHESS Depositary Interest ("CDI") Sale Facility for holders of less than a marketable parcel of CDIs in the Company ("Facility").

The Facility is only applicable to Thor Shareholders holding CDIs quoted on the Australian Securities Exchange (ASX). Under ASX Listing Rules, a process exists which allows listed entities to provide holders of parcels of securities valued at below A$500 the opportunity to sell those holdings without incurring brokerage or other transaction fees.

The Company is providing the Facility so that holders of less than a marketable parcel can sell their CDIs without incurring any brokerage or handling costs that could otherwise make a sale of their CDIs uneconomic and/or difficult. The Company will endeavour to obtain the highest available price for the CDIs and will organise remittance of sale proceeds for those CDI holders who participate in the Facility.

By making this Facility available, the Company also expects to reduce the administrative costs associated with maintaining a large number of small holdings.

The ASX Listing Rules defines a "Marketable Parcel" as those holdings of CDIs with a market value of $500 or more. As at market close on the 11 April 2018 ("Record Date") a parcel of CDIs in the Company is less than a Marketable Parcel for any CDI holding of 11,627 or less, based on the closing price of $0.043 per CDI.

As at the Record Date, the Company has approximately 3,036 CDI holders, of which approximately 2,551 hold Less Than a Marketable Parcel of CDIs comprising 3,732,834 CDIs in aggregate or 2.64% of all issued CDIs.

Holders of Unmarketable Parcels can either:

1. Retain their CDI holding by:

a. Signing and returning a Notice of Retention of CDIs Form accompanying the letter to CDI holders by 1 June 2018 ("Closing Date"). This will ensure non-participation in the Facility and their CDI holding will remain unchanged;

b. If they have multiple holdings, consolidate these under a single holding such that the combined CDI holding at the Closing Date is greater than $500; or

c. Purchasing additional CDIs under the same holding such that their CDI holding at the Closing Date is greater than $500.

Or

2. Sell their CDI holding by:

No further action is necessary. If their CDI holding at the Closing Date is less than $500, their CDIs will be sold and the proceeds sent to them.

Mick Billing, Executive Chairman, commented:

"This is an opportunity for holders of small parcels of Thor securities to either retain their holding or sell without incurring transaction fees."

"We expect that costs associated with maintaining a relatively large register of CDIs in Australia will reduce substantially".
