  abstract = {{S}mall-scale artisanal mining is a vital sector of the economy of {B}urkina {F}aso. {T}his activity, correctly regulated, remains essential for the population despite security issues since 2015. {E}xploration of new areas for gold mining in this condition is difficult but essential to continue extractive activities. {I}t is, therefore, important to define viable corridors, with science-based evidence for the good prospects, to support artisanal miners' activities in a way that minimizes the environmental impact. {W}e describe a remote sensing approach to study the structural control of expanding small-scale artisanal gold activity at the {B}ouda site and define future mining corridors. {T}his remote sensing approach can also mitigate and remedy environmental impacts. {T}he {M}inimum {N}oise {F}raction ({MNF}) is applied to {L}andsat images (7-{ETM}+, 5-{TM}, and 8-{OLI}, respectively, for 2000, 2011, and 2022) to detect extraction sites and perform a spatiotemporal analysis of the expansion of areas affected by gold extraction. {T}he near-infrared and mid-infrared bands of {L}andsat images significantly contribute to detecting extraction areas. {A} morphological study of the site over time and {P}rincipal {C}omponent {A}nalysis ({PCA}) on {L}andsat 8-{OLI} enable us to perform a lineament analysis. {T}he expansion of mining activity is structurally controlled, as revealed by the correlation between gold occurrences and high lineament densities, especially in the dominant {NE}-{SW} direction. {T}hese analyses suggest five potential prospecting corridors in the {B}ouda site. {B}ouda is an artisanal and small-scale mining district in {B}urkina {F}aso {R}emote sensing using {L}andsat images allowed us to study the structural control of the expansion of the {B}ouda site {R}emote sensing using {L}andsat images allowed to define future exploitation corridors of the {B}ouda site},
