Toronto, Ontario--(Newsfile Corp. - April 24, 2026) - Lipari Mining Ltd. (Cboe CA: LML) (FSE: 0Y90) ("Lipari" or the "Company") reports that its recently acquired kimberlite processing plant has arrived in the Port of Luanda, Angola. The plant was transported from Sudbury, Ontario to the Port of Montreal, Quebec where it was shipped by marine transport to Angola during Q1-2026. The delivery of this 5 tonne-per-hour processing plant will enable the Company to accelerate its Phase II development program on the Tchiuzo kimberlite, one of 30 kimberlites within the Company's Tchitengo Project in Angola.

Ken Johnson, Lipari's President and CEO, stated: "This shipment represents a significant milestone in advancing our Tchitengo Project in Angola, positioning Lipari Mining at a key inflection point in the Company's development. The plant is expected to process a minimum of 10,000 tonnes of kimberlite from Tchiuzo, which is anticipated to yield approximately 5,000 carats that will undergo valuation procedures to determine the current market value of Tchiuzo diamonds.

Together with results from last year's Phase I confirmatory drilling program, the valuation sampling program is expected to position the Company to update the historical feasibility study originally completed on the Tchiuzo kimberlite by Sociedade Mineira de Catoca ("SM Catoca") in 2013. SM Catoca reportedly invested US$35.6 million towards the exploration and development of the Tchiuzo kimberlite pipe during the period from 2006 to 2016."^[1]

As reported by the Company in its press release dated October 31, 2025 (see replicated table below), the Tchiuzo kimberlite contains constrained mineral resources comprised of an indicated resource of 28.8Mt containing 13.6Mcts at an estimated diamond grade of 47.2 cpht, and an inferred resource of 6.5Mt containing 2.0Mcts at an estimated grade of 30.7 cpht. The mineral resources were estimated based on a bottom-screen cut-off of +1.0mm.

Class of Resource	Lithology	Tonnes	Grade cpht (+1.0mm)	Carats (+1.0mm)
Indicated	TKB	13,215,774	48.7	6,434,374
TK	15,574,869	46.0	7,163,857
Total	28,790,642	47.2	13,598,231
Inferred	TKB	169,513	39.9	67,613
TK	1,583,630	36.0	570,107
SAPR	1,486,620	54.0	802,775
OVB	940,795	24.0	225,791
BVRS	2,285,546	14.0	319,976
Total	6,466,103	30.7	1,986,261

The independent and qualified persons for the mineral resource estimate, as defined by NI 43-101, are Sean Duggan of Z* Mineral Estimation Consultants for the block modeling and resource classification and Carlos Guzmán of NCL Engineering and Construction for the Reasonable Prospects for Eventual Economic Extraction ("RPEEE") analysis. Mineral Resources are reported as constrained by a pit shell optimized with overall slopes angles varying from 38° to 41°, mining cost of 3.7/t, $6.79/t for process and 98% recovery, $2.94/t for G&A, 5% for Government royalty and a diamond price of $100/ct. At this scenario the cut-off is 10.45cpht. Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained carats. Tonnage is in metric units and grade in carats per hundred tonnes. The estimate is based on a 1 mm diamond bottom cutoff size, appropriate for commercial diamond mining operations.

Directors Resignations and Restructuring of the Board of Directors

The Company also announces that Dr. Luiz Bizzi is retiring from the Board of Directors and as Co-Chairman of the Company, and he has tendered his resignation effective April 22, 2026. The Board of Directors thanks Dr. Bizzi for his leadership and support of the Company.

The Company also announces that Dr. Hermano de Villemor Amaral (neto) has also tendered his resignation from the Board of Directors. The Board of Directors thanks Dr. Amaral for his service and valuable contributions to the Company and wishes him continued success in his future endeavours.

As previously announced on April 8, 2026, the Company delayed the filing of its audited annual financial statements, management's discussion and analysis, and related certifications for the year ended December 31, 2025 (collectively, the "Annual Filings"). The Company is continuing to actively pursue alternative financing options to restore liquidity and allow its auditor to complete the audit process. Management now expects to be in a position to file the Annual Filings by May 31, 2026.
