Mineral exploration shall not an art or a game, it shall be a science. And science is not only technology; it is demonstrated theories and quantified predictions!

Faithful to its vision, IOS team will offer three talks at the Geological Association of Canada's annual meeting, in Sudbury, May 25–26 ^th, in the dynamic Harquail School of Earth Science at Laurentian University. Scattered in three different sessions, these talks will offer the geoscientist community with our last thoughts, techniques and results.

1: Critical Metals and Porphyry Cu deposit.

Offered by Dr. Olivier Nadeau, our team metallogenist, on Friday, May 26^th at 10:20 a.m. (eastern saving time) in SY01-6 session (Critical Minerals in Canada: Commodity overviews, exploration tools and method development), this talk will discuss how some critical metal such as selenium, tellurium and rhenium are distributed in porphyry copper systems and how they could be used for mineralization vectoring, beyond traditional alteration patterns.

2: Coupling EDS and EBSD (SEM) to identify LCT-pegmatites in tills.

Offered by Dr. Hugues Longuépée, scientific director, on Friday, May 26^th at 2:20 p.m. as part of SS20-3 session (Lithium in pegmatites: Mineralogy, petrogenesis and classics to innovative exploration technic), this talk tackle the issue that EDS-based analyses cannot detect lithium and consequently spodumene and other lithium indicator minerals liberated in glacial drift through the erosion of LCT pegmatites. The technique synchronizes an EBSD and EDS detectors for heavy mineral scanning in order to confirm the crystalline structure of the minerals to discriminate lithium bearing minerals from aluminosilicates.

3: Anomaly threshold in detrital dispersion: From statistics to stochastic!

Offered by M. Réjean Girard, on Thursday, May 25^th at 10:20 a.m. as part of SS21-2 session (Mineral Exploration Footprints). This talk, which is the culmination of nearly 40 years of reflection sheds a new light on “What is an anomaly?”. It offers a rigorous method of calculating the probabilities of a grain counts belong to a local anomalous signal or to the regional background in detrial dispersion, it can be used for indicator minerals or gold grain counting to evaluate the likelihood of an anomaly of being true signal or a random count.

Because innovation without application is merely research and entertainment!
