The Parker Challenge

Mineral Resource Estimation Conference 2023

The Parker Challenge

How much variability would there be if multiple geologists or geostatisticians all estimated and classified a mineral resource from the same data? The Parker Challenge aims to find out!

The Parker Challenge is now open!

In order to showcase the variability in contemporary mineral resource estimation and leverage the disparate skills, perspectives and knowledge of our industry’s professionals, The Parker Challenge is calling on all mineral resource estimators to create a classified model from the same base dataset.

Forming part of AusIMM’s Mineral Resource Estimation Conference 2023, The Parker Challenge sponsored by Rio Tinto, aims to quantify the ‘between person variance’ or ‘pattern noise’ in resource estimation. Participants will have until 24 March 2023 to complete the challenge.

Join the Parker Challenge

Thanks to The Parker Challenge sponsor, Rio Tinto, the winner will be rewarded with $55,000!

Why participate?

Presenting a unique opportunity to address the lack of transparency in MRE output and resource classification, The Parker Challenge will allow you to contribute to building a knowledgebase that will benefit the entire industry for years to come.

The dataset: Rio Tinto's Hugo Dummett South

All participants of The Parker Challenge will receive the dataset for Rio Tinto’s Hugo Dummett South, a polymetallic porphyry deposit, as well as basic background information, specifications for the final model, challenge instructions and entry requirements.

Identifying estimation variability

Your estimate will be amalgamated with estimates from every other participant and the results will be compared. The range of outcomes, differences in approaches and classification decisions will be presented during the conference, highlighting just how different the estimates can be given the same data.

Reward and recognition

Thanks to The Parker Challenge Sponsor, Rio Tinto, the winner will be rewarded with $55,000! The Challenge winner will be announced at the Mineral Resource Estimation Conference being held at Optus Stadium in Perth from 24-25 May 2023.

Dr Harry Parker

Dr Harry Parker was widely known and respected as an authority and expert in the field of resource modelling and geostatistics.  He emphasised the preparation of resource models that reflect both local geological controls on grade and orebody geometry as well as the degree of selectivity implicit in the mining method.  These insights were gained from combining an impressive breadth of experience with deep technical knowledge. Lifting The Parker Challenge trophy is a prestigious nod to a man for whom such an exercise would have been fascinating!

FAQs

Yes. We will be compiling all the models so we need a common (SMU) block size. Feel free to estimate at any block size but you must reblock to match the common format. The final grade tonnage curves and resource tabulation must use the specified SMU block size.

There is no limit on the estimation approach. As long as each block has an estimated value for all the required variables!

We recognise the impracticality of assessing the reasonable prospects for an anonymous deposit. Our focus is on understanding your approach to classifying the uncertainty of your estimate using a recognised resource reporting scheme. Therefore, assume the entire volume covered by the estimate meets the RPEEE threshold.

Participants should assume the quality of the sampling, analysis and logging is at a level sufficient for resource estimation. The data include a combination of drill hole types and holes from both underground and surface collar locations. While every effort has been made to ensure a ‘clean’ database, participants are advised to check for themselves.

Only the name of the winner will be shared publicly. It will be announced at the Mineral Resource Estimation Conference in May 2023. All entries will be combined to for anonymous comparison. The judges may award special recognition for non-winning entries that deserve mention.

The Parker Challenge excludes all current Rio Tinto employees and any sub-contractors (or persons) with previous or current exposure to or knowledge of the Hugo South site. Applications for consideration can be made and will be managed on a case-by-case basis with Rio Tinto.

If you have any questions, please do not hesitate to contact The Parker Challenge subcommittee at questions@parkerchallenge.info. The subcommittee will be monitoring the inbox over the Christmas holidays. Please note the AusIMM office be closed from the 23rd December 2022 to 8th Janaury 2023.
