The consistent recovery of such high-value diamonds is a testament to the geological richness of the Lulo concession and the efficacy of Lucapa’s mining strategies.
Operational Excellence and Strategic Mining: Driving Efficiency and Value
The remarkable increase in diamond production at Lulo is directly attributable to a significant enhancement in operational activities and strategic resource allocation. During Q2 2017, the project experienced a substantial 55% rise in mining volumes, reaching an impressive 57,283 bank cubic metres (bcm). This metric, crucial for assessing mining activity, indicates the volume of earth excavated and processed. The substantial increase in bcm signifies improved productivity and expanded mining operations, laying the groundwork for sustained high production rates.
Lucapa Diamond Company confirmed that this surge in mining volumes has positioned the Lulo project firmly on track to achieve its ambitious annual targets. The company is aiming for record annual volumes of 240,000 bcm for 2017, a goal that reflects both confidence in their operational capabilities and the robust potential of the concession. Achieving such a target would underscore Lucapa’s ability to consistently scale its operations while maintaining high recovery rates.
Beyond sheer volume, the quality of the recovered diamonds also saw notable improvements. The grade of the diamonds recovered during the quarter improved by 5%, reaching 7.3 carats per 100 cubic metres. Diamond grade is a critical indicator of the concentration of diamonds within the processed material; a higher grade signifies more carats recovered per unit of earth, directly impacting profitability. Concurrently, the average size of the diamonds recovered remained steady at 1.3 carats. This stability, coupled with the increased recovery of “Specials,” indicates that Lulo is consistently yielding diamonds of desirable size and quality, rather than simply increasing the volume of smaller stones. This balance of increased volume, improved grade, and consistent average size is a strong indicator of the project’s overall operational health and its capacity to deliver sustained value.
Strategic Shifts in Mining Blocks to Maximize Value
Lucapa’s operational strategy at Lulo is not just about volume but also about maximizing the value extracted from the concession. The company reported a strategic shift in its mining focus during the quarter. In April and May 2017, mining operations were primarily concentrated on Mining Block 28. However, in June 2017, the focus dynamically transitioned back to the higher-value Mining Blocks 8 and 6. This strategic reallocation of resources is a testament to Lucapa’s agile approach to operations, prioritizing areas known for yielding larger and more valuable diamonds. Such tactical decisions are crucial in alluvial mining, where diamond distribution can vary significantly across different blocks, and constant evaluation allows for optimal resource deployment and enhanced recovery of premium stones.
Robust Sales Performance and Healthy Inventory Management by SML
The financial health and market appeal of the Lulo Diamond Project are further evidenced by its strong sales performance and disciplined inventory management. Sociedade Mineira Do Lulo (SML), the Angolan-based operator of the Lulo alluvial mine, reported impressive sales figures for the period. Diamond sales in Q2 2017 generated US$4.8 million, contributing to a substantial US$15.4 million in sales for the first half of the year. These figures highlight the consistent demand and attractive pricing for Lulo’s unique diamond production in the global market.
As of June 30, SML maintained a healthy diamond inventory of 1,716 carats. This represents a significant 37% increase from previous periods, indicating a robust pipeline of high-quality diamonds ready for future sales cycles. Maintaining a substantial inventory provides flexibility in sales timing, allowing SML to capitalize on optimal market conditions and ensuring a steady revenue stream. The combination of strong sales, increasing production, and strategic inventory management positions Lucapa and SML strongly within the competitive landscape of the international diamond trade, reflecting both operational prowess and sound financial stewardship.
The Future Unfolds: Pioneering Kimberlite Exploration in the Cacuilo Valley
While the Lulo Diamond Project is celebrated for its prolific alluvial diamond recoveries, Lucapa Diamond Company maintains a keen strategic focus on unlocking the ultimate source of these magnificent stones. The long-term vision for Lulo involves locating the primary source or sources of the exceptional alluvial diamonds that have made the concession famous. These primary sources are typically kimberlite pipes or dykes, which are the geological conduits through which diamonds are brought from the Earth’s mantle to the surface. Discovering a significant kimberlite pipe at Lulo could transform the project from an alluvial mine to a much larger, longer-life, and potentially more valuable primary source diamond operation.
In pursuit of this ambitious goal, Lucapa has been actively engaged in advanced exploration. The company announced that it would soon provide a crucial update to shareholders regarding the results and interpretation of a comprehensive helicopter-borne Time Domain Electromagnetic (TDEM) survey. This state-of-the-art geophysical survey was conducted over the expansive Cacuilo Valley area at Lulo. TDEM surveys are advanced exploration tools that use electromagnetic pulses to map subsurface geology, identifying structures that could indicate the presence of kimberlite pipes, which often have distinct electromagnetic signatures compared to surrounding rock formations. The helicopter-borne nature of the survey allows for rapid and efficient coverage of large, often remote, areas, providing invaluable data for targeted exploration.
The insights garnered from the TDEM survey results are paramount for guiding the upcoming Lulo kimberlite drilling program. This drilling initiative is a critical step in physically investigating identified anomalies to confirm the presence of kimberlite. The program is specifically designed to pinpoint and delineate the diamond-bearing kimberlite bodies that are believed to be the original source of Lulo’s extraordinary alluvial diamonds. This meticulous approach to exploration leverages cutting-edge technology and geological expertise to maximize the chances of a significant discovery. Furthermore, the drilling efforts will be complemented by rigorous laboratory analysis of kimberlite core samples in South Africa.
