Canadian Mining Company with Mine in Peru Announces Successful Completion of Geotubes Testing Program for Its Plant
The objective of the program was to evaluate the suitability of various geotextile materials for use in geotextile containers, or “Geotubes,” which are intended to store tailings generated from the processing of both oxidized and sulfide ores at the Company’s processing plant.
The results demonstrated that a geotextile supplied by a Chinese manufacturer delivered exceptional performance, achieving high water clarity (sediment levels below the permissible limit of 50 milligrams per liter), efficient dewatering rates exceeding 70%, and low residual moisture in the retained solids.
The selected geotextile also proved to be highly cost-effective and is slated for use upon commencement of plant operations.

BREAKING NEWS

Intermas Workers Step Up Protests Over Forced Labour Changes
Montornès del Vallès, Spain 16 June 2025 — Tensions are rising at Intermas, a major manufacturer of plastic nets and geosynthetics, as employees escalate protests in response to the company’s unilateral imposition of new working conditions without union agreement.
According to local news outlet El 9 Nou, the company has proceeded with altering labour conditions despite lacking consensus with the workers’ committee. This breach of protocol has ignited a wave of demonstrations, with labour representatives organizing a series of concentrated protests in recent weeks.
“They are changing our working conditions without negotiation. This is not acceptable,” said one worker at a recent rally near the company’s Vallès facility.
The conflict signals growing unrest within the company, with unions accusing management of bypassing collective bargaining processes. Workers claim the changes will adversely affect shift schedules, job security, and remuneration structures.
Intermas has yet to release a formal statement addressing the workers’ demands or outlining its rationale for the imposed changes.
The ongoing protests are expected to intensify unless a negotiated resolution is reached. Legal observers suggest this could evolve into a broader labour dispute if mediation fails.

S&P Global Downgrades Groupe Solmax Inc. to ‘B-‘ With Stable Outlook
June 19, 2025 – Montreal – S&P Global Ratings has downgraded the issuer credit rating on Groupe Solmax Inc., a global leader in geosynthetics manufacturing, from ‘B’ to ‘B-’, citing increased credit risk and a reassessment of the company’s capital structure.
In the same action, S&P also lowered the issue-level rating on Solmax’s senior secured term loan, moving it from ‘B’ to ‘B-’. This downgrade reflects a combination of constrained financial flexibility, higher leverage, and what the agency views as a more aggressive capital structure than previously anticipated.
While the company’s stable outlook indicates that no further downgrades are expected in the near term, the lowered ratings underscore heightened concerns over the company’s ability to maintain liquidity and service its debt under current market conditions.
Solmax, which expanded its footprint significantly through a series of global acquisitions in recent years, may be facing integration and cash flow challenges as it balances operational costs and debt obligations.
The full S&P report can be accessed here.
