Since then, an increasing number of lithium brine projects in salt flats (salars) have been in development. According to the Argentina Government database (2024) [1], only 16% of lithium projects in Argentina are at a construction or production level, signifying that a majority of the projects are due to advance to eventual production. The Chilean Government has also expressed increased interest in the development of lithium brine projects through international collaboration and special contracts to explore for and extract lithium [2]. Mining projects at these advanced stages often require Qualified Persons (QPs) who have the education and relevant experience to ensure that scientific and technical information is appropriately generated and accurately reported. In 2024, 3 M&amp;A QPs \u2013Brandon Schneider, Megan Zivic, and Mike Rosko\u2013gave a lithium brine short course at the Prospectors &amp; Developers Association of Canada (PDAC) Conference and are providing lithium modeling and wellfield services to develop reconciliation programs for clients\u2019 advanced lithium brine projects transitioning to production.<\/span><\/p>\n<\/div><div class=\"fusion-text fusion-text-2\" style=\"--awb-margin-top:-30px;\"><h3>Defining Reconciliation for Lithium Brines<\/h3>\n<\/div><div class=\"fusion-text fusion-text-3\" style=\"--awb-margin-top:-20px;\"><p>Reconciliation is the process of identifying, analyzing, and managing the variation between planned and actual production results to improve mine performance [3]. In general, reconciliation is frequently recommended for prudent, timely, and informed management decisions, and it can be beneficial for long-term planning.<\/p>\n<p>Compared to traditional (solid) deposits, lithium brine reconciliation is challenging due to the mobilization of brine once wellfield pumping begins.

This mobilization results in a reconfiguration of the mass distribution over time and eventual changes in the extraction rate if a well\u2019s capacity degrades. Only a few lithium brine projects have evaluated reconciliation versus years of production or against a ramp-up phase of their initial production schedule. Thus, as more lithium brine projects advance, reconciliation will be increasingly important for subsequent reserve reporting and long-term planning.<\/p>\n<p>In the lithium brine industry, early-stage projects typically characterize lithium grade for the resource estimate using exploration well samples representing a specific or small depth interval. When moving to a reserve estimate, brine samples from short- and long-term pumping tests demonstrate temporal trends of grade and extractability of the brine, and samples represent a composite or average concentration over the entire screened interval of the pumping well. Composite sampling provides confidence in the brine profile and maturity of the deposit. Continuing with depth-specific samples may be impractical when in production, so the use of composite samples provides a more realistic determination of the average brine grade for processing purposes.<\/p>\n<p>A routine well monitoring program is required and more practical for assessing intermittent production plant and wellfield management, future Ore Reserves, and production reconciliation. A program such as this should include routine collection of composite brine samples at production wells, with the corresponding quality assurance-quality control measures and regular measurements of water levels and pumping rates. Monitoring programs should also include more distal observation wells for brine\/water levels and a characterization of the freshwater-brine interface to evaluate changes with production.<\/p>\n<p>Reconciliation will require periodic reserve model updates as the mine life decreases to incorporate measured time-series data from the production wells, any changes in well capacities, well monitoring program, evaporation measurements, precipitation, reinjected spent brine or infiltration from evaporation ponds, and monitoring from environmentally sensitive sites. Model behavior will be assessed against the measured data and, if necessary, recalibration of the reserve model will result in parameter adjustments to ensure that subsequent projections are adequate. Compared to an initial reserve, the calibration effort from production reconciliation may focus on an extended transient calibration to collective pumping, rather than individual pumping tests. Furthermore, depending on how the resources are reported (inclusive or exclusive of reserves), previously categorized resources could be reevaluated where confidence has increased due to demonstrated pumping and production.<\/p>\n<p>Figure 2 illustrates the overall process by which a lithium brine reserve model could be updated depending on the comparison of simulated and real production; in this example, a reserve model overpredicted extracted mass when compared to real production (during the same year). Model differences should be carefully evaluated for subsequent projections.<\/p>\n<\/div><div class=\"fusion-image-element \" style=\"--awb-caption-title-font-family:var(--h2_typography-font-family);--awb-caption-title-font-weight:var(--h2_typography-font-weight);--awb-caption-title-font-style:var(--h2_typography-font-style);--awb-caption-title-size:var(--h2_typography-font-size);--awb-caption-title-transform:var(--h2_typography-text-transform);--awb-caption-title-line-height:var(--h2_typography-line-height);--awb-caption-title-letter-spacing:var(--h2_typography-letter-spacing);\"><span class=\" fusion-imageframe imageframe-none imageframe-2 hover-type-none\"><img decoding=\"async\" width=\"1200\" height=\"385\" title=\"Figure 2\" src=\"https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2.png\" data-orig-src=\"https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2-1200x385.png\" alt class=\"lazyload img-responsive wp-image-12798\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%271468%27%20height%3D%27471%27%20viewBox%3D%270%200%201468%20471%27%3E%3Crect%20width%3D%271468%27%20height%3D%27471%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2-200x64.png 200w, https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2-400x128.png 400w, https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2-600x193.png 600w, https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2-800x257.png 800w, https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2-1200x385.png 1200w, https:\/\/elmontgomery.com\/wp-content\/uploads\/2025\/04\/Figure-2.png 1468w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 640px) 100vw, 1200px\" \/><\/span><\/div><div class=\"fusion-text fusion-text-9\" style=\"--awb-text-color:var(--awb-color6);--awb-margin-top:10px;\"><p style=\"text-align: center;\"><strong>Figure 2: Reconciliation of the Reserve Model Using Production Data<\/strong><\/p>\n<\/div><div class=\"fusion-text fusion-text-10 fusion-text-no-margin\" style=\"--awb-margin-top:-20px;--awb-margin-bottom:-20px;\"><h3>Final Thoughts<\/h3>\n<\/div><div class=\"fusion-text fusion-text-11\"><p>Lithium brine extraction is a growing industry with unique challenges. Robust programs and procedures are needed for future reconciliation due to the mobile nature of the brine.
