    • Geostatistical simulations with heterotopic hard and soft data without modeling the linear model of coregionalization 

      Araújo, Cristina da Paixão; Bassani, Marcel Antônio Arcari; Koppe, Vanessa Cerqueira; Costa, Joao Felipe Coimbra Leite; Soares, Amílcar de Oliveira (2021) [Artículo de periódico]
      Most mining decisions are based on models estimated/simulated given the information obtained from samples. During the exploration stage, samples are commonly taken using diamond drill holes which are accurate and precise. ...

    • Improving short-term grade block models: alternative for correcting soft data 

      Araújo, Cristina da Paixão; Costa, Joao Felipe Coimbra Leite; Koppe, Vanessa Cerqueira (2018) [Artículo de periódico]
      Short-term mining planning typically relies on samples obtained from channels or less-accurate sampling methods. The results may include larger sampling errors than those derived from diamond drill hole core samples. The ...

    • Integration of different-quality data in short-term mining planning 

      Araújo, Cristina da Paixão; Costa, Joao Felipe Coimbra Leite (2015) [Artículo de periódico]
      Decisions, from mineral exploration to mining operations, are based on grade block models obtained from samples. This study evaluates the impact of using imprecise data in short-term planning. The exhaustive Walker Lake ...
