According to recent studies this year, new information from the Geological Survey Authority and Mineral Resources has revealed almost 30 gold-bearing locations across Yemen. Sites possessing significant quantities of gold have been found in the governorates of Hajjah, Hadramout, Saada, Jawf, Abyan and Sana’a.
These same sources say that initial estimates of crude gold reserves in the Alharka area of the Hajja governorate reach almost 39 million tons of gold-bearing rock. Each ton contains between one and sixty-five grams of gold. This information is highly encouraging to potential investors in Yemen’s gold economy.
Estimations of gold reserves in other Yemeni locations have not been released due to the lack of detailed studies. However, geochemical indicators suggest the presence of gold in strong proportions: between one eighteen grams per ton of gold-bearing rock. Quartz vein ratios, which are prevalent in the governorates listed above, spread into other adjacent areas in Hajjah such as, Aahm, Wadi Harad, Baalan, Wadi alhoreara, Wadi Sharas. In Saada, Quartz veins have been found in the Alfeiad area, Wadi Marwan, Wadi Aleryad, Haydan, Wadi Alnachor, and Mahfr.
The Survey Authority has also stated that the special regions in Hadramout are located on “basis rocks,” which date back to the Alpricamanri Era. This region is rich in volcanic, sedimentary metamorphic and also granitic rock.
According to recent Survey Authority studies performed this year, the Madn Valley of Hadramout contains approximately 678,000 tons of gold-bearing rock, with approximately 15 grams of gold per ton.
Studies in the Al-Jawf governorate, have identified gold strains in Sberan, Allov, Wadi Al-Kaheel, Wadi Flhan, Wadi Ataaf Rbag, Wadi Alnamash, Almtmh, and Rayyan. In the Abyan governorate, gold has been discovered in Nagd Almlaja, Shataba, Moajb, and the Am Sarra area. Sana’ani gold reserves have been identified in Bahra, Yam, and Nakil Killan.
Chairman of the Board of the Survey, Dr. Amer Mohsen Sabri, told the Yemen News Agency (SABA) that metal exploration projects in Yemen are carried out using entirely modern methods. Exploration is conducted by the Yemeni government with some help from the United Nations and friendly countries, as well as a number of foreign mining companies. These explorations have revealed a number of locations bearing high-quality gold and other minerals.
Dr. Sabri says that the search for gold contains three steps. First comes the initial search, which lasts for 3–5 years. This search is then followed by exploration of selected sites, which takes an additional 5-15 years. Finally, promising sites undergo a “development” process for an additional three years.
Dr. Sabri also stated that the most important gold locations in Yemen are located at sites rich in “basis rocks” from the pre-Cambrian era, rocks which are considered part of the Arabian Shield rocks. These specific geological conditions provide a high likelihood of finding gold in Yemen, specifically in areas rich in volcanic rock. Such regions include Vamar in Otama, Waraka, and the Atheen area of Yemen’s western plateau. The gold in these regions can be found 12 to 32 grams per gold-bearing ton.
The gold explored in the Aluwazeih area of Taiz has been found 0.6 grams per ton; in the Shahra region of Amran 0.5 grams per ton, in Kwlan and Sana’a three to five grams per ton, and in the Alfakar area of the Aa’b governorate 0.5 grams per ton.
Dr. Sabri commented that old gold mines have been revealed in the governorates of Al-Jawf, Saada, and Shabwa. These areas will need more detailed studies before the existence of these mines can be confirmed.
