About the Lac à Paul property
The Lac à Paul property contains an Anorthositic suite of the Lake-Saint-Jean Group which itself lies within the Grenville geological province. The regional metamorphism is generally high-grade and is at the higher end of the amphibolite facies and into the granulite facies. The rocks present on the property of the Lac à Paul  belong to a mafic to ultramafic sequence made up of anorthosite, leuconorite, norite, gabbronorite, gabbro (with olivine), pyroxenite, and locally, nelsonite, peridotite, dunite and magnetite. Thus, the phosphate deposits of the Lac à Paul are of igneous origin. 

This novel technique offers the same objectivity for each meter of drill core. The results of the analyses are subsequently linearized to show the various sequences along the length of the hole. The image below shows the results from hole 08-01. It also shows a comparison of the results of the Core Mapper™ against the assay data.

In the final stage of analysis, the data collected by the Core Mapper™ is seamlessly integrated into a 3D imaging software which clearly displays the distribution of the various mineral species of the deposit. This visualization makes it possible to interpret, in a very precise manner, the various zones of mineralisation, which in turn, permits strategic drill hole target selection using real time information.

Ressources d'Arianne Strater
Ressources d’Arianne is currently developing a phosphate and titanium project in the region north of the Saguenay-Lac-St-Jean and will release the prefeasibility study shortly. At this stage, a solid understanding of geology and formation processes of the deposits is critical in order to optimize the mineral extraction process.  It is here that Photonic Knowledge’s Core Mapper™ has made a significant contribution. Because the Core Mapper™ can deliver results depicting the drill core’s chemistry and the physics simultaneously, it has set the stage for a geological and economic breakthrough.

The chemical analysis carried out in the laboratory revealed that the igneous rocks from Lac à Paul presented a very high concentration in P2O5.  Indeed, in the literature the igneous rocks enriched in P2O5 are primarily carbonatites or nelsonites.  In the case of the deposits from Lac à Paul we deal with nelsonites which should contain to the maximum, 13% P2O5. However, certain analyses of the rocks from Paul Zone revealed grades reaching 21.3% P2O5. These results far exceeded the normal expected readings and raised people’s interest in the project.  An understanding of the processes at the base of this re-enrichment of phosphorus can make it possible to better interpret the structure for this type of deposit and to develop corresponding exploration tools.
Ressources d'Arianne apatite

The results speak for themselves! Nadège Tollari, Ph.D., Vice-President Research and Development at Ressources d’Arianne remarked. Core Mapper™ system was used to confirm the occurrence of two phases of the crystallization of apatite (the mineral containing phosphorus). This is the likely explanation for the abnormally high presence of phosphorus detected in the rocks from Lac à Paul as determined following the analysis of these samples.

“The tests carried out in laboratory treat a significant amount of data, but do not provide us enough explanation.” states Ms. Tollari. “We can clearly see in the image provided by the Core Mapper™ , that there are three types of apatite. We are also able to observe the result of these two phases of crystallization, which explains the high grade of phosphorus. The Core Mapper™ has proven the existence of these three types of apatite over 4,500 meters of core analysis. These results were available in less than one month and were less expensive, approximately 1/10th the cost of the traditional methods.”  The Core Mapper™ provides an unequalled level of analysis; it captures six boxes of drill core at a time with a resolution 900 times more precise, and a field of view 1666 times larger than any spectrometer, and in addition, the whole acquisition cycle requires less than 15 minutes! “The quality and the volume of data provided would, quite simply, not have been economically possible within a reasonable time frame using traditional tools” added Ms. Tollari.
