Editor's Notes
- We’re going to walk you through the new features in 8.13, as well as our roadmap for the rest of 2020. In the Q&A we’ll focus on questions about the new features. If your question relates to support, please submit it through the support portal. And finally, we’ll share next steps to get started with the new feature, trial supervisor or request a demo.
- Thankyou Kristy. And thankyou everyone for taking time out of your day to watch the webinar. Whether you’re joining us from the mine site or from your living room, I’m glad you could make it. Before we have a look at the new features we’ve just added to Supervisor, I wanted to take a bit of time to discuss the design principles behind what we are doing here at Snowden. Adding features is more than just putting another shiny bauble on the tree. So, take a second to think about the challenges we face as resource estimators... And I don’t just mean engineers. I’m sure many of you could produce a list several pages long and some of you could write a book on it (In fact some of you probably have). Supervisor is designed will those challenges in mind.
- When we say created by geologists, we mean people that understand the difficulties faced in the mining industry. We’ve all been stuck late at the office, with looming deadlines and software that just won’t give us the result we are looking for. And by the 5th iteration we’re looking at our keyboard wondering “if I throw this hard enough, I wonder if it will make it to the go line”. Supervisor is intuitive and easy to use because we’ve built it to follow the practical process that geologists use day-to-day both in the office and at the mine. It’s our software of choice just as much as it is yours. I’ve used many different softwares during my studies and career and believe me, I would not have taken this role or use this software if I didn’t genuinely believe that it was the best tool for the job. The pressure to deliver great resource work is immense, all the consultants here at Snowden can attest to that, but Supervisor takes care of the stats and lets you focus on the geological problems so that you can deliver to an exceptional standard every time. Snowden has a long legacy of highly skilled and talented individuals, all of whom have passed on their knowledge and experience into the Supervisor software, and it really shows.
- When we consider what it is about Supervisor that helps mine geolgists and Resource Managers succeed, I really boil it down to these key points. 1. The first one is simple, if a software is difficult to use, it’s not saving you time. Supervisor is easy to use because the user is guided by the project tree through the simple steps of statistical analysis, spatial analysis, variography and estimation. Every part of the process has clear links to the data so that you always know where you are in the process and don’t get lost along the way. It’s the confidence that if you are interrupted halfway through because the shift boss has changed the plan and is calling for a last minute ore markup, you know exactly where you left off and can get straight back into it. 2. Secondly, learning a new software can be one of the most frustrating work experiences in the world and usually, the more experienced you are, the more frustrating it is. You know the process but you just can’t figure out how to get the DARN thing to do it. When we implement a new feature in Supervisor we are always conscious of the experience of the user. We are constantly reviewing our components and looking for ways we can make them easier to understand without the user having to refer to the manual every 5 minutes. We want to get to the point that it is so easy to use that anyone that understands resource estimation can pick up our software and use it out of the box. 3. The third point is about simplifying the complexity of resource estimation. It’s easy to not know where to begin in geostatistics. So often the technical barrier for entry is so high that it is daunting for new practitioners. You really don’t need a PhD to produce good resource estimates. In fact the largest contributor to a great resource estimate is a clear understanding of the geological controls within your deposit and the correct use of an appropriate technique. When it comes to good resource estimates, whether or not you know the intimate details of every equation and transformation, is usually more of a philosophical issue than an actual one. More often than not our issues stem from low quality data or a poor understanding of the deposit, so lets keep the focus there and not get caught up in the maths. Save that for the classroom when we don’t have the next model due-date breathing down our neck. Particularly for those that learn by doing rather than reading, we want Supervisor to nurture your development as you play and experiment with new techniques. 4. Our fourth major consideration is about how we present our results. How do our results provide the information we need to determine that we have done a good job and what do they tell us about our deposit that we didn’t already know. One of the main reasons that we have delayed the release of our conditional simulation component is that we did not believe that it met our standards for producing useful and insightful results. So lets go now and have a look at the new 8.13 features.
- Supervisor 8.13 brings back conditional simulation from version 7, but with a few major enhancements. If you used conditional simulation in version 7 you’ll recognise the QQ plot, optimum digline and even the GT curve to an extent. But that’s where the similarities end. We’ve spent a lot of time talking to our pre-release users and the consultants here at Snowden so that we could drill down to what it is exactly that we want to achieve when we run a simulation. The code to run a simulation is out there and freely available, but there’s more to a simulation than plugging in a few numbers and getting some different numbers out the other end. Where is the value and what problems could we solve? Surprisingly, or not, it was generally the post processing that was the most valuable and the most difficult to generate. So we set about designing a suite of components that we and our users could actually use to provide the answers that we set about using simulation to get in the first place.
- Conditional simulation has been around for a very long time. Chances are, if you haven’t used it then you’ve at least heard of it. Some of the benefits we wanted to bring this time around was not only the ability to run multiple realisations, but also to run across multiple domains too. It keeps the workflow tidy and puts all your results in one place. We’ve also simplified the generation of nodes as much as possible. You can choose to create your grid from a specified area, a loaded block model, or a csv point file. In the case of a model, it will also honour the domain coding within the model for generating the simulations.
- The QQ plots and Optimum digline components have made a return in this release. The QQ plot is an obvious addition, and being able to compare all the simulations at once often provides a lot more context than if we were to attempt to compare them one at a time. The Optimum digline component stems from work done by Ian Glacken, whom I believe may be in the audience now. It allows the user to code blocks not only by a probability above a certain cutoff, but also tweak that threshold through the use of resource preservation and risk aversion factors.
- The Improvements to the GT curve analysis was a clear decision. Too often we spend so much time manually post processing our simulations, extracting the data to excel, sorting and combining records and finally trying to plot up a semi-decent chart so that we can start interpreting the results. If the results are no good, we are back to square one and have to go through the whole process in multiple softwares all over again. The new GT curve analysis component is designed to cut straight to the interpretation and offers three different views in which the user has full control over how the data is displayed and compared. Loaded block models can now be validated against the simulation swarm with the same control as our model validation tool. An envelope can be drawn around your simulations with control lines and boxplots able to be toggled to demonstrate the variability at each cutoff. All of these tools are designed to help cut the amount of time wasted moving from product to product so you can get the answers you want right here and now.
- Another new component to our post-processing suite are the probability plots. One of the major benefits of conditional simulation is that it allows you to produce potential grade histograms for each block. We can then easily use this information to determine the probability that a block will be over a certain grade cutoff. The probability plots allow you to generate several grade cut-offs and visualise the areas that have higher or lower probabilities of grading above those cut-offs. It can be a quick way to determine where you may have higher or lower confidence in your data and all the results can be exported for further investigation if necessary. Another next tool is the ability to step through the model, using a slider, in not just the Z direction, but also the X and Y directions. Larger models may tke a minute to load up the plots, but once loaded I think you’ll like how smoothly you are able to step through and visualise the results.
- Because the results of the conditional simulation are tables, they are compatible with almost all our other supervisor tools too. You can add histograms and mean and variance plots. You can even copy your variography from your point data to check that the results honour the inputs. Just remember that you are now working with a dataset that is likely to be a degree of magnitude or two larger than the input data and you should expect longer run times. With the ease of generating these simulations from your variography and a loaded domain model, we hope to see this feature easily incorporated into your existing workflows as an additional investigation or validation tool for your estimates. Youtube Video for a demo.
- Just before we look ahead to the rest of 2020, I just want to highlight some of the features you may have missed in our past releases. In particular Version 8.11 introduced kriging in the form of LKNO. The component can be used to generate a range of parameters and test each one, or used with a single parameter set for your standard estimation. Between versions 8.11 and 8.12 we’ve also developed the Topcut analysis tools which are particularly useful in bring all the considerations for your topcut into one space. Scattered among these major releases are several other component enhancements which are listed in greater detail in the release notes that accompany the software. In case you weren’t aware, you can find the release notes in the Supervisor installation folder.
- Over the next month we will be working on the stability of 8.13, reviewing bug reports and making fixes. However, I also wanted to talk about what we are working towards in the next major release
- Simulation is a powerful tool for univariate applications, however, the randomness inherent in the technique does not lend itself well to multivariate data. In normal circumstances, the correlations between variables break down due to this randomness and in the worst case a closure problem occurs where the sum of the assays is equal to more than 100% of the rock. Unfortunately I didn’t have time to illustrate the effect of simulating two variables without any other considerations, but I’m sure that those of you that have tried it understand the mess that it creates. Supervisor 8.14 will include the Multivariate simulation component which will allow users to perform simulations which honour the correlations of the input data, just as you see on the screen here. Normally this is a process with several steps requiring multiple data transformations, however we are pleased that we have been able to combine all the necessary requirements into one easy workflow that takes care of the manual handling for you.
- Looking forward to the rest of 2020, we have an abundance of features which we are working on. Some of these, like the conditional simulation suite we’ve released already, while others are still in various stages of development. These features have generated from direct conversations with our users and from the feedback we received in our last survey. We always want to make sure that we are focussing our efforts towards features that solve our users problems and are going to be valuable immediately. And that’s where you come in
- When it comes to the development of Supervisor, we want to ensure that our users are as involved in the process as possible. So we’ve been putting together some new ways in which you can get involved.
- The first way to be heard is the simplest. In the same place for inquiring about sales or support, you have the ability to send us suggestions about what you want to see added or improved in Supervisor. Simply head to the portal shown here or in the link which we’ll put in the chat. Every suggestion is discussed and prioritised based on the time it would take to be implemented. We do our best to make sure that features that have benefits for the majority of our users always make it to the top of the list. So get heard and send us your suggestions.
- We believe that our software is as user friendly as it is today because it has been developed to put the geologist first. By involving our users more closely in our development we can ensure that we meet your needs. Soon we will be inviting current Supervisor users to become members of the Snowden pre-release program. As a member you will have access to new features that are in late stages of development so that you can assist with their growth through feedback and testing. These features will be regularly updated as you and other users provide feedback to our developers who will update and add additional features to meet your needs. Most importantly, having live feedback and testers will allow us to identify bugs faster, focus our development on things that matter and ultimately reduce the time it takes to polish and stabilise new features so that we can get them into your hands sooner. So keep an eye out and look forward to becoming part of our next major release.
- Finally, we’d love to hear from you if you have a great case study to share with our other Supervisor users. We can also assist with anonymising yourself or the data, and focus on the beneficial messages of the work. As always we are available at the Snowden email if you want to get in touch.
