Al-Juhani: Based on the results of the analysis, it will be clear how feasible it is to continue working in these sites

Nasser Al-Jahdali, chief geologist, explained to “Previously” that the Geological Survey Authority received a letter from a citizen, who lives in the Jizan region, in which he indicated the existence of gold sites near Sabya Governorate. The aforementioned site was signed on maps, aerial photography and satellite images, determining the site’s spectral footprint, and verifying the presence of other sites in the area. After that, the targeted sites were visited, and it turned out that they are veins of quartz, which cut through the diorite rocks, and their thickness ranges from half a meter to several centimeters, and directed northwest-southeast at about 280-300 degrees north, and inclines towards the northeast, covering a large area . This is considered one of the favorable geological environments for the presence of gold in the region. Many samples were collected for analysis, and to know the gold concentrations in them.

For his part, Chief Geologist Abdullah Al-Juhani pointed out that the Jizan region, like all regions of the Kingdom, contains many mineral sites, both metallic and non-metallic. There are 41 mineral sites in the region, 39 of which are minerals and industrial rocks, such as limestone, marble, sandstone, salt, black sand and kyanite, and they represent 95% of the total sites. The metallic sites are represented by two iron ore sites.

He continued: All these sites were discovered during the regional survey work of the region with different drawing scales by several bodies, such as the Ministry of Mineral Resources and geological missions, such as the French and the United States 40 years ago, and currently the Saudi Geological Survey since its inception has taken upon itself to carry out regional surveys and mineral exploration. In Saudi Arabia.

He said that previous surveys and explorations did not indicate the existence of gold ore sites in the Jizan region, and during this exploratory trip to the region, a number of sites of gold ores associated with the quartz veins were identified. And based on the results of the chemical analyzes of the samples, it will be evident the feasibility of continuing work at these sites, but the initial surveys are promising, God willing.

He added: I would also like to point out that all the mineral sites previously mentioned are documented and archived in the National Geological Database of Earth Sciences, or the so-called Documentation System for Mineral Sites (MODS). All the information and technical data of the mineral sites are posted on the platform or the authority’s electronic portal; To be within the reach of investors and researchers in the field of geosciences.

For his part, geologist Zaban Matar Al-Harbi, head of the metallurgical department, stated that this exploratory visit to a number of sites with good indications of the presence of gold in quartz veins is the first step.

And Abizaid: followed by visits to detailed geological studies in the event that encouraging results of gold emerge from the samples collected. He pointed out that the detailed studies include collecting more samples, mapping, making geological sectors, as well as conducting geophysical studies to find out the depth of the veins. In advanced stages, exploration wells will be drilled to calculate the mineralized resources, and to determine the economic viability of the sites.

Previously, it had revealed in a previous report that gold digging and search operations were carried out by unknown persons in separate locations east of Sabya.
