Estimating future losses is integral to setting aside appropriate reserves in the insurance industry. This study analyzes di erent Chain Ladder reserving methods based on weightedleast square regression that consider di erent function of weights. These methods are tested on 78 NAIC fully developed loss triangles.

resource estimate is the critical fundamental foundation of all mining projects. All work done must be compliant with the relevant code SAMREC or JORC etc. Reserve estimates The reserve estimate gives an indiion of the viability of the mineral resource. Calculation of the reserves will depend on the mining method, including an estimate on
31/12/2020 · The method of estimation is very simple and easy to implement in mine planning sector. OK method is a probabilistic method of valuation in order to figure out the uncertainty of ore deposit [10]. Kriging estimator unites the covariance of different points in a sample and covariance between the sample loion and prediction point [11].

05/06/2020 · During the gold rush, miners stripped large areas of shallow goldrich ground down to the bedrock and processed the earth they removed using equipment such as tubs, cradles, puddling machines and sluices. This method of mining is known as "surfacing" and evidence of it can be found in abundance throughout the Victorian Goldfields.
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
