Ethically sourced diamonds with verifiable provenance have become the defining standard in the global diamond industry. Lipari Mining (LML.NE: FRA) operates at the forefront of this transformation, seamlessly integrating geological significance with unwavering accountability. From Brazil’s volcanic kimberlites to the heart of Angola’s renowned central diamond district, the company is preserving Earth’s ancient formations while building a future rooted in transparency, community and innovation. “We don’t simply extract diamonds; we deliver trust, integrity and a compelling story our customers can proudly share,” says Ken Johnson, president and CEO. Lipari produces natural diamonds from its mines, ensuring every stone’s journey is secure and traceable through a fully auditable chain-of-custody process. Its operational model is designed to respect the land, foster community growth and deliver diamonds that buyers can wear with pride. Each mine is developed and run with a focus on environmental innovation, geological integrity and social impact, creating a standard where beauty, responsibility and transparency are inseparable. Proven Results Backed by Heritage and Innovation Lipari’s Braúna mine in Brazil stands as a globally recognized operation distinguished by its extraordinary geological heritage, historic significance and industry-leading environmental practices. The diamonds recovered here are over 642 million years old—true time capsules formed during the Cryogenian period. Braúna also holds a pioneering place in mining history as the first diamond mine in Latin America developed from a kimberlite deposit, the same volcanic rock that hosts the majority of the world’s diamond resources. Environmental stewardship defines its operational approach. Braúna is the only diamond mine in the world without a tailings dam. Its advanced processing facility employs a state-of-the-art dewatering circuit to recover and recirculate 98 percent of the water used during ore processing. This produces dry tailings that can be safely stockpiled, eliminating the long-term risks associated with conventional tailings ponds. The dry kimberlite tailings are also undergoing trials as soil remineralizers, potentially supplying valuable nutrients to nearby agricultural communities. Complementing its rich history and sustainable practices, Braúna has demonstrated remarkable operational consistency. While global market disruptions like the COVID-19 pandemic, U.S. tariffs and sanctions created temporary pressures, tightening worldwide supply has strengthened demand for responsibly sourced rough diamonds. Throughout varying market conditions, Braúna’s diamonds have maintained an average sales value of around USD 185 per carat, reflecting the mine’s consistent size and quality distribution....Read more

Top Mining Optimization Software in Latin America 2025
MiningMath is redefining strategic mine planning through technical innovation. For decades, open-pit mining operations have relied on segmented workflows. Conventional software forced engineers through a sequential process that risked compromising project value. MiningMath’s single-step optimization engine disrupts this paradigm, replacing fragmented procedures with a unified, data-driven system that delivers globally optimized solutions. This transformative approach is now being embraced by leading copper producers across Latin America, among other major international mining companies. “MiningMath delivers global solutions that maximize value and respect constraints, all optimized simultaneously within a unified mathematical model,” says Alexandre Marinho, co-founder. Overcoming Legacy Planning At the core of MiningMath’s industry disruption is integrating geometrical constraints required for pit design and production scheduling into a unified optimization run. Unlike traditional methodologies that lock in suboptimal decisions early, such as block destinations, nested pits, and pushbacks, MiningMath’s algorithm optimizes mine envelopes, destinations, block sequences, and Net Present Value (NPV); all simultaneously. This approach provides users with a global view of trade-offs, enabling more creative mining sequences that yield schedules maximizing NPV by up to 68 percent compared to traditional planning methods, according to users’ feedback. Instead of a single final solution, MiningMath can produce hundreds of distinctive mine plan alternatives. Operations such as Sierra Gorda in Chile are already translating MiningMath’s theoretical outputs into operational plans, demonstrating feasibility and tangible real-world impact. Efficiency is another hallmark. For multi-pit and multi-stream operations, such as PGM deposits with intricate scheduling requirements, this unified framework enables comprehensive, one-pass optimization across every project dimension. The result is measurable improvement in project economics and greater confidence in decision-making. ...Read more

IN FOCUS
Latin America's Diamond Supply Chain Revolution
Latin American diamond producers are revolutionizing the industry by embracing transparency, vertical integration, and technology, reshaping supply chains and redefining the value of diamonds.
EDITORIAL
The New Frontier of Mining
In the modern mining landscape, two forces are reshaping the industry: the ethical production of diamonds and the advanced technology that optimizes mining operations. On one side, diamond producers are transforming the way precious stones are sourced, focusing on transparency, sustainability, and community impact. On the other hand, mining optimization software is driving efficiency and precision, helping companies maximize output while minimizing their environmental footprint. Together, these forces are not just changing how we mine; they're redefining what it means to mine responsibly and profitably.
Companies like Lipari Mining (LML.NE) and MiningMath are at the forefront of this transformation.
Lipari Mining (LML.NE) stands as a leader in the ethically sourced diamond sector, ensuring that provenance and transparency are integral to their operations. From the volcanic kimberlites of Brazil to Angola’s central diamond district, Lipari seamlessly blends geological expertise with a commitment to environmental responsibility. The company’s focus is on creating a fully traceable supply chain that guarantees every diamond’s origin is secure and verified. Lipari’s approach fosters accountability across the entire value chain, offering diamonds that are not just rare but ethically sourced and fully traceable. Its vision extends beyond extraction to build communities and sustainable practices that create longterm value for both people and the planet.
MiningMath is redefining strategic mine planning through technical innovation. For decades, open-pit mining relied on fragmented workflows where conventional software required engineers to follow a sequential process, often compromising project value. MiningMath’s modern, single-step optimization engine disrupts this model. By unifying the mining process into a data-driven system, it delivers globally optimized solutions that improve operational efficiency and project outcomes. This transformative software is quickly gaining traction, especially among leading copper producers in Latin America, and is now being adopted by major mining companies worldwide.
This edition explores how together, Lipari Mining (LML.NE) and MiningMath represent a new era of mining, where innovation, efficiency, and responsibility go hand in hand. While Lipari is setting the standard for ethical sourcing, MiningMath’s advanced software is driving a more efficient and sustainable future for the industry.
