    Open pit mining is the preferred method for the extraction of ore from deposits that are close to the surface, since the cost per tonne of ore mined is generally lower than that for underground mining Other factors that may influence the decision about whether to mine using open pit or underground methods include the ore grade, the geometry of the deposit, other physical characteristics, andmine’s block sizes and pit geometry KEYWORDS Openpit mining, Interramporientation, Bench face orientation, GIS, Integrated design, Block modeling CITATION Grenon M, Laflamme A J Slope orientation assessment for openbased pit mines, using GIS algorithms Computers & geosciences (2011) 37(9), 14131424 This is the author’s version of the original manuscriptThe final publicationSlope orientation assessment for openpit mines, using GIS· Compared to the inferred mineral resource of 219 million ounces of gold (2897 million tonnes grading 235 g/t Au) outlined in April 2020 (see Company press release dated April 17, 2020), further drilling has now increased the Adumbi inferred mineral resource by 44% to 315 million ounces of gold (41316 million tonnes grading 237 g/t Au), constrained within a US$1,500 open pit shell (seeLoncor Increases Open Pit Mineral Resources by 44% to
