Completion of the Acquisition is subject to, among other things: (i) the approval of the TSX and the NYSE MKT, (ii) any waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 having expired or been terminated, or clearance otherwise having been granted by the relevant governmental authorities, (iii) the Company raising gross proceeds of at least US$65,000,000 in equity financing, (iv) the receipt of all other necessary third party authorizations, approvals and consents, and (v) other customary conditions typical of a transaction of this nature.

The Offering

The Company has entered into an agreement with a syndicate of underwriters (the "Underwriters"), who have agreed to purchase for resale, on a bought deal private placement basis, 20,000,000 Subscription Receipts at a price of C$5.00 per Subscription Receipt (the "Offering Price"), for aggregate gross proceeds of C$100,000,000.

Klondex has also granted the Underwriters an option, exercisable up to two business days prior to the closing date of the Offering, to purchase of up to an additional 3,000,000 Subscription Receipts at the Offering Price for additional gross proceeds of up to C$15,000,000.

Upon the satisfaction of all conditions precedent to the Acquisition (other than the payment of the purchase price), and provided that the conditions have been satisfied by the date which is 90 days post closing of the Offering, the proceeds delivered into escrow will be released to the Company and each holder of Subscription Receipts will receive, without the payment of additional consideration or further action on the part of the holder, one special warrant (a "Special Warrant") of the Company, with each Special Warrant entitling the holder to acquire, for no additional consideration, one common share of the Company (each, a "Common Share"). The Special Warrants will be exercisable by the holders thereof at any time after the closing date of the Acquisition for no additional consideration and all unexercised Special Warrants will be deemed to be exercised on the earlier of: (a) the date that is four months and a day following the closing date of the Offering, and (b) the third business day after a receipt is issued for a (final) prospectus by the securities regulatory authorities in each of the Provinces of Canada where the Subscription Receipts are sold (other than Quebec) (the "Qualifying Provinces") qualifying the Common Shares to be issued upon the exercise or deemed exercise of the Special Warrants (the "Final Qualification Prospectus").

The Company will use its commercially reasonable efforts to file a prospectus in order to qualify the issuance of the Common Shares upon conversion of the Special Warrants in Canada. It is expected that the prospectus will be filed following the preparation of a technical report in respect of the Hollister Mine, if required in accordance with applicable securities laws, and the preparation of the necessary audited and unaudited financial statements and pro forma financial statements relating to the Acquisition Assets in accordance with applicable securities laws.

The Company intends to use the net proceeds of the Offering: (i) to fund the cash purchase price of the Acquisition and replacement of reclamation bonds currently in place with United States and Nevada regulators, (ii) for exploration growth at the Hollister Mine and Esmeralda Mine and (iii) development at the Hollister Mine.

The Offering is scheduled to close on or about August 18, 2016, and is subject to certain conditions including, but not limited to, the receipt of all necessary approvals including the approvals of the TSX and the NYSE MKT.

The securities to be issued under the Offering will be offered by way of private placement exemptions in all the provinces of Canada and in the United States on a private placement basis pursuant to exemptions from the registration requirements of the United States Securities Act of 1933, as amended. All securities issued pursuant to the Offering, including the Subscription Receipts and the Special Warrants, will be subject to a statutory four-month hold period in accordance with Canadian securities legislation, subject to the prospectus qualification referred to above.
