Chemical Assays
Assaying a geological sample using traditional methods is both time consuming and destructive. Minalyzer CS provide fast high resolution assays based on X-ray Fluorescence. Receive more assay data while reducing sample preparation and logistics, without increasing the assay budget.
Continuous Measurement
The X-ray Fluorescence spectral data is acquired through a continuous scan along the complete length of the sample. The X-ray beam footprint for scanning drill core is 20 x 1 mm. The width of this beam on the sample makes the analysis less subjective, repeatable and highly representative when compared to traditional bulk analyzes from laboratory.
Highly Representative
The XRF spectrum is stored on a cm resolution and can be integrated into any interval above 10cm. The standard delivery of Minalyze geochemical data is intervals of 1m, 10cm and one client interval (usually the assay splits). Due to the scanning nature of the data collection compared to spot analysis the Minalyzer results are highly representative of the lab results. Clients have found the high resolution geochemistry (10cm intervals) useful for identifying contacts, distinguishing veins and classifying different rock types when logging reducing logging time and standardizing logging methods.
Non-Destructive
Scanning of the samples is completely non-destructive and minimal sample preparation is required. The sample surface should be visually clean from any dust, mud and other contaminants. Keeping your samples intact enables for subsequent mechanical testing and saves time on time consuming tasks of sample preparation such as splitting, cutting, crushing and grinding the samples.
Multi-elemental
The elemental range spans from elements Mg to U in the table of elements, providing whole rock analyses for your complete project. Find correlations between elements that you previously have not included in your analytical suite and develop proxies, ratios and indexes.
Compatible dataset
The quantified assay data is available as a comma separated table format which enables for easy import in your database or modelling software such as Leapfrog® and Micromine®. It is possible to align the data taking distance markers and core loss into account.
Case Studies
Arsenic-rich Zones in Nickel Sulphide Mineralisation
Rönnbäcken nickel project is located in northern Sweden, and was until recently explored by Nickel Mountain Group AB.
Estimation of Fe in Magnetite
An important distinction in Fe exploration is to determine in which mineral phases the Fe is hosted, rather than just the total Fe content.
Geochemical Core Logging with Minalyzer CS
Unravelling geology is oftentimes a complicated occupation, especially in areas with a history of ore-forming processing.
