Te wikitoria i ngā wero o te VMS Ore i te haona o Āwherika: Ngā matūriki koura matatau mō Eritrea
Kei te tere whakaū a Eritrea i tōna tūranga hei pūngao nui i roto i te rāngai keri o te Horn of Africa. Me ngā mahi o te ao pēnei i te maina polymetallic Bisha (konutea-parahi-koura-hiriwa) me te putunga koura Koka (Zara Mining Share Company), kāore e taea te whakakorekore i te taonga whenua o te motu. Heoi anō, kāore a Eritrea i te kore he arai hangarau tino uaua. Ko ngā putunga Volcanogenic Massive Sulfide (VMS) matua me te taiao ā-rohe uaua e hiahia ana ki ngā otinga matū tino motuhake.
E toru ngā wero nui, motuhake hoki e pā ana ki ngā tohunga whakarewa e mahi ana i Eritrea. Tuatahi, ko te rangahau mineralogi: He rongonui ngā putunga VMS mō te nui o te parahi me te konutea wairewa. Ka mahi ēnei konganuku tuarua hei "cyanicides" kaha, ka pau te nui o te Sodium Cyanide i mua i te tango i te koura, ka nui haere te OPEX. Tuarua, ngā here taiao: Ko te āhuarangi maroke o Eritrea te tikanga he mea nui te wai. Ka whakatinanahia e te Eritrean National Mining Corporation (ENAMCO) ngā kaupapa here kore-kino pakari e pā ana ki ngā Whare Rokiroki Tailings (TSF) hei tiaki i te iti o te wai whenua. Tuatoru, ngā mahi whakahaere o te Moana Whero: Ko ngā utanga e tae mai ana ki te Tauranga o Massawa ka pāngia e te pāmahana raumati neke atu i te 45°C. Ko te kawe i uta i muri mai i ngā whenua paripari, maunga ki ngā wāhi maina tawhiti e hiahia ana ki te takai matū e kore e taea te whakangaro me te ātete wera.
United Chemical kua hangaia he kohinga motuhake o ngā matū tango koura hei wikitoria i ēnei wero o Eritrea. Mā te whakaiti i te pokanoa o te konganuku turanga, te whakarite i ngā ratonga wera nui, me te whakarato i ngā huarahi rerekē e tutuki ana i ngā whakaritenga taiao, ka whakamanahia e mātou tō tipu ki te whakatutuki i ngā reiti whakaora teitei me te whakaiti nui i te whakamahinga matū katoa.
