Aten??o. N?o seguir viés Nao tenha medo de recome?ar, quanto melhor e mais correta for a metodologia de seguir o protocolo, maior sera sua representatividade.

En el caso de toma de muestras de forma manual, es muy sensible el protocolo a seguir, en vista de que varía bastante entre las diferentes personas asignadas a la toma de muestra y el horario de la toma, siendo las horas de la madrugada en donde más variabilidad ocurre.

Considerar la doble muestra para validar el método, la toma de muestra y el laboratorio. Lo anterior generalmente son considerados en casi todos los procedimientos y protocolos.

The main reason we have all these protocol calls of JORC Code, the NI 43-101, or the SAMREC Code is because people lied and cheated. Find a good lab or hire trusting samplers. It's mining. We don't have to bullshi+ with the language.

Após a coleta e análise das amostras de um depósito mineral, é crucial revisar e validar os resultados obtidos. Isso envolve verificar a consistência dos dados, identificar possíveis erros ou viéses e comparar os resultados com os objetivos iniciais da amostragem. Além disso, é importante considerar a precis?o dos métodos de análise utilizados e a representatividade da amostra em rela??o ao depósito como um todo. A revis?o cuidadosa dos resultados ajuda a garantir a confiabilidade das conclus?es e a tomar decis?es informadas em rela??o ao depósito mineral.

Considerar en el análisis de eficiencia y confiabilidad del muestreo la segmentación por periodos y no sólo quedarse con un sólo valor, esto para ver la evolución a través del tiempo.

Após a coleta e análise de amostras, a verifica??o minuciosa dos resultados é crucial. Métodos como análise estatística, gráfica, de duplicatas e de reconcilia??o s?o aplicados para identificar erros, vieses ou discrepancias nos dados. Comparando os resultados com outras fontes, como estudos anteriores ou modelos geológicos, permite avaliar a qualidade e confiabilidade dos dados. Essa abordagem rigorosa possibilita ajustes necessários para garantir a integridade dos dados, assemelhando-se a um processo de refinamento, semelhante a aprimorar uma imagem antes de apresentá-la. Essa prática visa assegurar que os dados coletados sejam confiáveis e representativos, proporcionando uma base sólida para tomada de decis?es embasadas e eficientes.

Small-Scale Keep it to yourself until you have started mining. Large-Scale Run and tell everyone so you can raise more money.

Após revisar os resultados da amostragem do depósito mineral, é fundamental comunicar as descobertas de forma clara e precisa. Isso inclui elaborar relatórios detalhados que descrevam os métodos utilizados, os dados coletados, as análises realizadas e as conclus?es alcan?adas. A comunica??o eficaz dos resultados é essencial para informar as partes interessadas, como investidores, gestores e outros profissionais da indústria mineral, sobre a viabilidade e as características do depósito.

Ensuring a representative sample of a mineral deposit involves several steps: 1. **Understand the Geology**: Gain a thorough understanding of the geology of the deposit, including its mineralogy, structure, and alteration. This knowledge helps in determining where to collect samples. 2. **Sampling Strategy**: Develop a sampling strategy that considers the deposit's size, shape, and variability. Use techniques like systematic sampling, random sampling, or stratified sampling to ensure representation. 3. **Sample Collection**: Collect samples from various locations within the deposit, taking into account factors like depth, orientation, and lithology. Use proper sampling tools and techniques to avoid contamination.

4. **Sample Preparation**: Prepare samples by crushing, grinding, and homogenizing them to ensure a consistent particle size and distribution. This step is crucial for obtaining accurate analytical results. 5. **Analysis**: Analyze the samples using appropriate techniques such as X-ray fluorescence (XRF), X-ray diffraction (XRD), and chemical assays to determine their mineral composition and grade. 6. **Data Interpretation**: Interpret the analytical data in the context of the deposit's geology and sampling strategy. Assess the representativeness of the samples and adjust sampling methods if necessary.

7. **Quality Control**: Implement quality control measures throughout the sampling and analysis process to ensure the reliability and accuracy of the results. 8. **Documentation**: Document all sampling procedures, including sample locations, collection methods, and analytical techniques, to maintain a record of the sampling process. By following these steps diligently, you can increase the likelihood of obtaining a representative sample of a mineral deposit, which is essential for making informed decisions in exploration and mining projects.

Para definir el protocolo de muestreo se deben realizar estudios de la variabilidad del o los elementos a muestrear. Si el muestreo y análisis es multielementos se debe dise?ar el protocolo de muestreo para el mas variable y así se puede asegurar que los demás elementos estarán con mayor precisión y exactitud.

It is the responsibility of the Mine Geologist to ensure that the drilling area is in good condition for drilling. Dozing or grading might be required in some areas for the drill rig and the hole set up. It is the responsibility of the Mine Geologist to ensure that the coordinates of the set of holes are available to the Mine Surveyor for the mark out or holes set up. The grade control or the drilling pattern map and the sheets with drilling depth information are made available to the Senior Technician by the Mine Geologist. Depending on the field condition, a change to the drilling pattern might be required to make sure full sampling coverage area can be done, and every hole planned is drilled.

Trust... It depends on the minerals and metals. If it's ferrous metals, trust what the people tell you; if it's rare earths, trust your people; if it's precious metals and minerals, don't trust a soul.

In my experience historical data for the area would benefit at the objective stage. Timing of the objective as well, would benefit, such as not underestimating the costs and possible over runs, due to climate conditions and workforce availability. Assuring a positive outcome by contracting to qualified and established contractors.

Fa?a um protocolo com base nos erros de GY e tente garantir um IC de 95%, se conseguir isso estara com uma boa representatividade.
