Argo Graphene Locks In Lubricant Data While Chicago Refinery Site Nears Finish Line

Argo Graphene Solutions is closing in on a home for its proposed graphene refinery in the Chicago area, though the site had not yet been secured as of the company's October 22 update. The announcement also carried preliminary results from lubricant testing and fresh detail on the production targets the planned facility is meant to hit.

Shares of the company rose 5.8% to €0.6900 on the day of the disclosure. That advance followed a 2.4% decline in the prior session, when the stock closed at €0.6520.

Capacity Targets Span Two Product Lines

The Chicago refinery is designed to start at roughly 10 metric tons of graphene per quarter — an initial operating level the company is aiming for, not output it has already achieved. From there, Argo's expansion blueprint calls for scaling to about 90 tons per quarter.

Alongside the graphene targets, the plans include a quarterly capacity of 30 tons of graphene oxide dispersion at a 20% concentration. Both figures describe intended capacity rather than current production.

Lubricant Trials Show Weeks-Long Dispersion

In the same release, Argo reported preliminary tests of graphene in specially formulated mineral oil. According to the company, the material stayed dispersed in the oil over a period of several weeks. The trials covered concentrations ranging from 0.05% to 0.50% by weight.

Argo presented the observations in connection with its lubricant testing program and explicitly labelled the findings as preliminary.

Option Grant Adds Corporate Context

Roughly two weeks before the update, Argo granted stock options to directors and consultants, entitling them to acquire up to 1,200,000 common shares in total. The exercise price stands at $1.25 per share.

The options vested immediately upon grant, meaning recipients faced no further waiting period before the rights became exercisable. The company set October 9, 2029 as the expiry date for exercising them. The disclosure covered the grant of these acquisition rights — not any exercise already completed or the issuance of the underlying common shares.
