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 kaimahi whakarewa e mahi ana i Eritrea. Tuatahi, te tātaritanga o ngā kohuke: He rongonui ngā putunga VMS mō te nui o te parahi me te konutea wairewa. He "cyanicides" kaha ēnei konganuku tuarua, e pau ana te nui o te konutai Cyanide i mua i te taea te wetewete i te koura, ka tino pupuhi ai te OPEX. Tuarua, ngā herenga taiao: He mea nui te wai nā te maroke o te āhuarangi o Eritrea. E whakatinanahia ana e te Eritrean National Mining Corporation (ENAMCO) ngā kaupapa here kore-kino 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 tau ana ki te Tauranga o Massawa ka pāngia e te pāmahana raumati e neke atu i te 45°C. Ko te kawe i ngā utanga ki uta i muri mai i ngā whenua paripari, maunga ki ngā wāhi maina tūmatanui e hiahia ana kia hangaia he takai matū e kore e taea te whakangaro, ā, he tino ātete ki te wera.
