Solaris Resources yatangaje ko umushinga wayo wa Warintza muri Ekwateri wavumbuye ibintu bikomeye. Ku nshuro ya mbere, ubushakashatsi burambuye ku birebana n'ubutaka bwavumbuye uburyo bwa porphyry bunini kurusha uko byari byitezwe mbere. Kugira ngo ubushakashatsi bwihutishe kandi bwongere ubushobozi bw'umutungo, ikigo cyongereye umubare w'ibikoresho byo gucukura biva kuri 6 bigera kuri 12.
Ibisubizo by'ingenzi by'ubushakashatsi:
SLSW-01 ni wo mwobo wa mbere uri mu bubiko bwa Valin Sasi. Intego ni ukugenzura ikibazo cy’ubutaka mu by’ubutaka, kandi cyashyizwe mu bikorwa mbere y’uko ubushakashatsi ku bumenyi bw’isi burangira. Uwo mwobo ufite metero 798 mu bujyakuzimu bwa metero 32, ufite uburebure bwa metero 0.31% bw’umuringa (umuringa 0.25%, molybdenum 0.02%, zahabu 0.02%), harimo ubugari bwa metero 260, umuringa ungana na 0.42% by’amabuye y’agaciro (umuringa 0.35%, molybdenum 0.01%, zahabu 0.02%). Uru ruzinduko mu kirombe rwabaye ikindi kintu gikomeye cyavumbuwe mu mushinga wa Varinsa.
Ibisubizo by’ubushakashatsi ku bumenyi bw’isi byagaragaje ko umushinga wose, harimo n’ibintu bidafite aho bihuriye n’ubushobozi bwo gutwara ibintu mu kirere hagati, iburasirazuba n’iburengerazuba muri Varinsa, bifite uburebure bwa kilometero 3.5, ubugari bwa kilometero 1, n’ubujyakuzimu bwa kilometero 1. Uburebure bw’amashanyarazi bugaragaza ko imiterere y’amabuye y’agaciro nk’ay’imitsi ifitanye isano rya bugufi n’imiterere y’amabuye y’agaciro yo mu muringa yo mu rwego rwo hejuru muri Varinsa. Itandukaniro ryigenga ry’ubushobozi bwo gutwara ibintu mu kirere mu majyepfo ya Varinsana riruta imiterere y’imiterere y’isi, rifite uburebure bwa kilometero 2.3, ubugari bwa kilometero 1.1, n’ubujyakuzimu bwa kilometero 0.7. Byongeye kandi, havumbuwe ikintu kitari cyaramenyekanye mbere, Yawi, gifite uburebure bwa kilometero 2.8, ubugari bwa kilometero 0.7, n’ubujyakuzimu bwa kilometero 0.5.
akazi ka geofiziki
Soleris yahaye akazi Geotech Ltd. gukoresha ikoranabuhanga rigezweho rya Z-axis tilting electron electromagnetic (ZTEM) mu gushakisha umushinga wa Valinsa ufite ubuso bwa kilometero kare 268. Ikoranabuhanga rigezweho niryo rikoreshwa muri ubu bushakashatsi. Intego ni ugushushanya agace kanini ka porphyry gafite ubujyakuzimu bw’ubushakashatsi bugera kuri metero 2.000. Nyuma yo guhindura amakuru ya electromagnetic mu buryo butatu yavuye mu bushakashatsi, hakorwa ibintu bidasanzwe bifite ubushobozi bwo gutwara amashanyarazi menshi (ubudahangarwa buke) (munsi ya metero 100 ohm).
Valinsa yo Hagati, Iburasirazuba n'Iburengerazuba
Ubushakashatsi ku miterere y’ubutaka bwagaragaje ko ibintu bidasanzwe binyura hagati muri Varinsa, Varinsa y’Iburasirazuba na Varinsaci, kandi bikomeza neza, kandi uburebure bwabyo bugera kuri kilometero 3.5, ubugari bwa kilometero 1 n’ubujyakuzimu bwa kilometero 1. Muri Varinsa, ibintu bidasanzwe bifitanye isano rya bugufi n’ubucukuzi bw’amabuye y’agaciro bwimbitse, mu gihe ubucukuzi buri mu butaka cyangwa hafi y’ubuso bugaragara nabi. Umukandara w’amabuye y’agaciro wa El Trinche wavuzwe mbere usa nkaho ari wo mu majyepfo ya Valinsa, ufite ubuso burebure budasanzwe bwa metero 500, ubugari bwa metero 300, n’umuringa uri hagati ya 0.2 na 0.8%. Varinsasi isa nkaho ari igice cy’iburengerazuba cy’ikibaya cyaciwe n’amakosa muri Varinsa, kandi ni ubucukuzi bw’amabuye y’agaciro buri mu rwego rwo hagati.
Hagati muri Mutarama, gucukura mu gice cyo hagati cya Valinsa byigeze kubona metero 1067 z'amabuye y'agaciro, afite umuringa ungana na 0.49%, molybdenum 0.02%, na zahabu 0.04 g/toni. Gahunda za mbere zo gucukura Trinche na Valinzadon zizatangira mu gice cya mbere cy'umwaka.
Valrinsanan
Valinsa y'Amajyepfo ni ahantu hanini higenga hafite imikorere myinshi itwara amazi, hagana mu majyaruguru y'uburengerazuba, mu birometero 4 mu majyepfo y'ikirombe cyo hagati cya Valinsa. Ahantu hafite imikorere mibi hafite uburebure bwa kilometero 2.3, ubugari bwa kilometero 1.1, ubugari bwa metero 700, kandi hatwikiriwe na metero 200 z'ubujyakuzimu. Hashobora kuba hari ahantu hakwirakwijwe cyangwa hamenetse ku gice cyo hejuru cy'amabuye y'agaciro, hakagaragaza imiterere mibi ya geochemical. Gahunda y'ibanze yo gucukura igomba gutangira mu gice cya mbere cy'umwaka.
Yawei
Yawei yari itaramenyekana mbere ariko yavumbuwe binyuze muri ubu bushakashatsi bw’isi, kandi iherereye muri metero 850 mu burasirazuba bw’agace ka Varinsa gateye ubwoba. Agace kateye ubwoba gaturuka mu majyaruguru ugana mu majyepfo, gafite uburebure bwa kilometero 2.8, ubugari bwa kilometero 0.7, ubugari bwa kilometero 0.5, kandi gatwikiriwe na metero 450 z’ubujyakuzimu.
Perezida akaba n'umuyobozi mukuru w'ikigo, Daniel Earle, yagize ati: “Twishimiye cyane kuba twavumbuye ibintu bishya bikomeye muri Valin Sasi. Birenze ubushobozi bwacu. Gushakisha imiterere y'ubutaka bigaragaza ko sisitemu ya porphyry metallogenic ari nini kurusha uko byari byitezwe mbere. Kugira ngo twihutishe gucukura no guteza imbere iterambere ry'umutungo, ikigo cyongereye umubare w'ibikoresho byo gucukura kugeza kuri 12.”
