Reading the warrant overhang on a mining junior

What a warrant is

A warrant is an issuer-issued option giving the holder the right to buy a defined number of shares at a fixed exercise price for a defined period — typically 2 to 5 years. Mining juniors issue warrants as a sweetener attached to placement units: a unit might be one share + one full warrant ('full warrant'), or one share + half a warrant ('half warrant').

Warrants are dilutive when exercised — every exercise adds new shares to the count, lowering the per-share value of the company. But they also bring cash into the treasury at the exercise price, which is sometimes useful for advancing a project.

Calculating the overhang

The warrant overhang is the total number of warrants outstanding × the dilution they'd cause if all were exercised. A junior with 100 million shares outstanding and 20 million warrants exercisable has a 20% overhang.

The overhang is most relevant for warrants that are in-the-money (exercise price < current share price) and near expiry. Deep out-of-the-money warrants with years to run are less likely to be exercised. In-the-money warrants close to expiry are nearly certain to be exercised — and traders position around the expected dilution.

How warrant exercise affects price

When a warrant is exercised, the holder pays cash to the issuer and receives a new share. They may sell that share into the open market to lock in the gain. Mass exercises ahead of a warrant expiry can therefore drive sustained selling pressure that depresses the share price.

The mitigating factor is the cash inflow. If the issuer has been waiting on warrant exercise to fund the next exploration program or feasibility study, the dilution is matched by progress — and the market typically prices it accordingly.

What to track

For every junior you follow, check: total warrants outstanding, weighted-average exercise price, weighted-average expiry date, and the breakdown of in-the-money vs out-of-the-money warrants. Most of this is in the latest financial statements (under Capital Stock / Warrants).
