Wondima Rough Resource CalculationArea of wondima is 50 sq.kmLets discount it by 50% and assume 25 sq.km host the iron resourceAverage depth till date is more than 8 m. Lets discount it to 5m.Assume density of iron is 7000 kg/m3.Assume 30% average gradeRsource size in ton=5000 x 5000 x 5 x 700 /1000 =875 million tons at 30% iron.Insitu value assuming $100 per ton = 875 million x 0.30 x 100 = 26 billion dollars !!!>
