The aim of this.s.udy is.to contribute to better targeting of gold pros.ecting areas.us.ng geos.atial information. To this.end, 3 mining s.tes.were s.lected for the s.udy. They are: the s.noufo belt (Barrick Gold mine), the yaouré complex (Pers.us.Mining mine) and the s.uth Fetêkro belt (Bonikro, Hiré and Agbaou mines.. For this.s.udy, a multi-s.ale approach was.carried out at regional, mine and micros.opic levels. At the regional s.ale, a comparative analys.s.of 1:200,000 s.ale geological maps.revealed that 3 main lithologies.are regularly repeated on and around the various.mining s.tes. Thes. are: undifferentiated volcanics. metagranodiorites.and metas.ltites.dominated by meta-arenites. Mos. of thes. lithologies.are affected by undifferentiated faults.generally oriented NE-s., N-s. ENE-Ws. and WNW-Es.. In addition, gold and manganes. occurrences.are pres.nt on all the s.tes.s.udied. At the mine s.ale, radars.t-1 images.proces.ing indicate that the main mining s.tes.are generally located near or at the inters.ction of lineaments.oriented NE-s. or N-s.on the one hand and E-W or ENE-Ws. or WNW-Es. or again NW-s. on the other. Thes. mines.are als. located at the interface between zones.of high and low lineament dens.ty. At the micros.opic s.ale, petrographic s.udies.of undifferentiated volcanic s.mples.from the various.s.tes.indicate that they cons.s. of andes.tes. meta-andes.tes.and tuffs.

Convolutional neural networks.s.ruggle to accurately handle changes.in angles.and twis.s.in the direction of images.which affects.their ability to recognize patterns.bas.d on internal feature levels. In contras., Caps.et overcomes.hes. limitations.by vectorizing information through increas.d directionality and magnitude, ens.ring that s.atialinformation is.not overlooked. Therefore, this.s.udy propos.s.a novel expres.ion recognition technique calledCAPs.LE-VGG, which combines.the s.rengths.of Caps.et and convolutional neural networks. By refining andintegrating features.extracted by a convolutional neural network before introducing theminto Caps.et, ourmodelenhances.facial recognition capabilities. Compared to traditional neural network models. our approach offers.as.er training pace, improved convergence s.eed, and higher accuracy rates.approaching s.ability. Experimentalres.lts.demons.rate that our method achieves.recognition rates.of 74.14% for the FER2013 expres.ion datas.t and99.85% for the CK+ expres.ion datas.t. By contras.ing thes. findings.with thos. obtained us.ng conventionalexpres.ion recognition techniques.and incorporating Caps.et’s.advantages. we effectively addres. is.ues.as.ociatedwith convolutional neural networks.while increas.ng expres.ion identification accuracy.
