The workers at the Niobec mine are still on strike which no doubt hasn't helped the mine's reputation as a reliable supplier.. Here's an article in French dated 21.6.25:

Niobec mine union members refuse agreement in principle
Published June 21 at 9:41 UTC+12
Workers at the Niobec mine in Saint-Honoré rejected on Friday the agreement in principle presented to them by the company's management and the Unifor union.
Radio-Canada noted on site that Niobec employees voted by a large majority against the agreement. About a hundred of them gathered at the Le Montagnais hotel in Chicoutimi to vote.They thus declined an offer of a salary increase of 25.4% spread over five years, which represented a salary increase of 32,000$ annually, according to the average salary of workers.
From Monday, mine employees will therefore be back on the picket line.The union and the employer will subsequently negotiate again the renewal of the collective agreement which expired on April 30, 2025. Union representatives previously mentioned that the main issue in the negotiations is salary in nature.
Niobec's 360 employees are on an indefinite general strike since May 1. The last collective agreement was signed in 2021, in the heart of the pandemic.

The strike may be behind the spike in FeNb price shown by Fastmarkets:

Trump's Liberation Day tariffs were announced on 2 April and that may have been a factor.
I've been monitoring the Fastmarkets page for some time now and converted it to US$/kg from %. I can't guarantee the accuracy but it's probably a reasonable approximation.
