“…The use of 3D modelling of potential fields (e.g. magnetics and gravity) has become an important tool in mineral exploration (Li and Oldenburg 1995, 1998; Oldenburg et al 1996) as it can provide relevant information for target generation (Fitzpatrick and Large 2015). 3D modelling has been mainly implemented within academic environments (Oldenburg and Pratt 2007; Lelìvre et al 2009) and the use in mining exploration has been increasing this last two decade as the algorithms and the computer calculations have been improved (Vallée et al 2011).…”

Geophysical data processing further constrained inversion is evolving progressively prevalent in geoscience domains for three-dimensional modelling and resources evaluation. The process is based on the magnetic and gravity data processing further constrained Cartesian cut cell inversion to discern the maximum of information about HAJJAR deposit in order to calculate its tonnage. This article exhibits data and inversion processing technique for tonnage calculation based on an important geophysical magnetic and gravity surveys of defined extent of HAJJAR region, which presents a great benefit to save time and have accurate and realistic results to a same case. Otherwise, the potential-field signatures of what are regarded to be geologically expressive features are sought within the magnetic and gravity data. The preliminary stage for tonnage calculation was residual anomaly processing and depth estimation of the orebody using spectral analysis method. However, progressing towards extracting the deposit signature, the used method leads to invest the gravity signature of the orebody in adequacy with the magnetic signature. Finally, the tonnage calculation was developed by constrained Cartesian cut cell inversion using Voxi Earth Modelling TM . Obtained results were very important, given their qualitative and quantitative accuracy, which give an added value for the governmental geological and geophysical survey.
