Mining is an important part of Canada's economy. Today, mineral exploration is moving to deeper or smallerdeposits; methods are required that can effectively unify all geoscientific data and improve the potential toresolve such challenging deposits. Gold and other ore deposits can be delineated using various techniques thatwork with different forms of geological and geophysical data. Proven methods exist that develop ore depositmodels from geological information, and others that develop models from geophysical information. Thecurrent procedure is to derive geological and geophysical models independently, from each type of information,and perform qualitative comparisons. However, the models rarely match well, having geometrical orpetrophysical differences, and model comparison often requires too much speculation. The question is thenhow to reconcile the independently-derived models into one consistent, unified picture of the Earth'ssubsurface. In the last several years there have been several independent critical scientific advances in 3Dmodelling, many of which have been lead by the applicant's research group. However, less work has been doneinto methods that incorporate multiple sources of geoscientific data towards unified ore deposit models. Theproposed research looks at ways to place those advances into a single unified framework that can leverage allavailable geophysical and geological data, pull quality geological products out, and ultimately help predict andrefine ore deposit models to better delineate ore resources. The outcomes of this project will give Barrickaccess to technologies and services that are not available to other companies in the world. This will helpmaintain or increase Canada's share of the world-wide mining industry.

矿业是加拿大经济的重要组成部分。如今，矿产勘探正在转向更深或更小的矿床;需要能够有效统一所有地球科学数据并提高解决此类具有挑战性的矿床的潜力的方法。黄金和其他矿床可以使用各种技术来描绘，这些技术与不同形式的地质和地球物理数据一起工作。存在从地质信息开发矿床模型的建模方法，以及从地球物理信息开发模型的其他方法。目前的程序是从每种类型的信息中独立地导出地质和地球物理模型，并进行定性比较。然而，模型很少匹配良好，具有几何或岩石物理差异，并且模型比较通常需要太多的推测。现在的问题是如何将独立导出的模型协调成一个一致的、统一的地球表面下的图像。在过去的几年里，在3D建模方面有几个独立的关键科学进展，其中许多是由申请人的研究小组领导的。然而，较少的工作已经做到方法，将多个来源的地学数据，以统一的矿床存款模型。拟议的研究着眼于如何将这些进展纳入一个单一的统一框架，可以利用所有可用的地球物理和地质数据，提取高质量的地质产品，并最终帮助预测和改进矿石存款模型，以更好地描绘矿石资源。该项目的成果将使Barrick获得世界上其他公司无法获得的技术和服务。这将有助于保持或增加加拿大在世界矿业中的份额。
