NEWS RELEASE

Excelsior Mining Closes US$9.4M Equity Placement with Greenstone Resources and

Confirms Stock Option Exercise Program

December 6, 2018

Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the “Company”)

is pleased to announce the closing of a US$9.4 million equity placement with affiliates of Greenstone

Resources L.P. pursuant to the terms of a previously announced subscription agreement (see Excelsior

news release dated November 21, 2018 – Greenstone Resources Confirms US$9.4 Million Equity

Placement). Excelsior has issued to Greenstone an aggregate of 13,050,840 Excelsior common shares

at an aggregate subscription price of US$9.443 million, or equal to approximately C$0.95 per share at

current exchange rates (the “ Greenstone Financing”). Greenstone now holds a total of 113,928,937

Common Shares, whic h represents approximately 48.56% of Excelsior’s issued and outstanding

Common Shares. The common shares issued to Greenstone in the Greenstone Financing are subject to

a statutory four-month plus one-day hold period expiring on April 6, 2019.

Stock Option Exercise Program

The Company also confirms that it has implemented a stock option exercise program (the “ Program”)

for the block of stock options that expire as of December 31, 2018. These stock options were originally

issued from 2010 to 2012 and have been held by optionholders for 6-8 years. The intention of the Program

was to minimize any impact on the Company’s share price by avoiding the sale of a large block of shares

all at once or over a short time period. The Program was also set -up to minimize dilution resulting from

the exercise of stock options. The Program involved two steps. Firstly, optionholders completed a “net

exercise” whereby optionholders receive a net amount of shares by reducing the amount they would

otherwise be issued to cover the exercise price. The second step was the Company repurchased from

each optionholder (at the market price) a sufficient number of shares to cover the taxes of the

optionholders associated with the exercise. As a result of the Program, a total of 1,630,727 shares were

repurchased by the Company and cancelled, and a final net amount of 3,407,479 shares were issued to

optionholders. The Program was completed without any shares being sold in the market to cover exercise

price or tax obligations.
