Providing expert advice to the Canahuire project in southern Peru
In August 2010, Canteras Del Hallazgo S.A.C., (CDH) a joint venture between Gold Fields Ltd. and Compania de Minas Buenaventura S.A.A., commissioned SRK Consulting Canada to provide expert structural geology advice into the exploration and resource delineation programs at the Canahuire Project in southern Peru. read full article…
More and more, geophysics is becoming an important exploration tool as companies turn their efforts towards hidden and buried deposits. However, it is vital to know the limitations of both the techniques and data when designing, implementing and interpreting the results of a geophysical program. read full article…
Rapid assessment of structural geometries for brownfield targeting, Burkina Faso
An understanding of the structural controls on zones of mineralisation is of fundamental importance for brownfield exploration efforts. The combination of field geology observational skills with new, rapid, computerised modelling tools enhances SRK’s ability to provide rapid three-dimensional answers to clients. read full article…
Target generation and grassroots exploration in Mauritania
In 2010/11 SRK Exploration Services was commissioned by Alecto Energy plc to conduct its grassroots copper/gold exploration program in Southern Mauritania. From the outset, SRK’s involvement started with visits and meetings with the Mauritanian Ministry of Mines on Alecto’s behalf. read full article…
SRK Exploration Services Ltd (SRK ES) was established in Cardiff in 2003 as a small group of like-minded exploration geologists with a view to filling a perceived gap in the consultancy market. Initially formed as a subsidiary company of SRK Consulting UK, SRK ES achieved full SRK Consulting Practice status in 2008. read full article…
Applying conceptual geometrical models in evaluating mineral prospects
Continuity of geology and grade are key traits that must be demonstrable during the process of estimating a reportable Mineral Resource. Too often, however, assay grade takes precedence in interpreting the so-called geological model, while the geology – lithology, structure and alteration – are vastly underused or even ignored during the modelling process. read full article…
Brownfield exploration poses many challenges to the geologist: large amounts of data are usually available but often difficult to integrate and use effectively; at the same time old ideas and exploration models often hamper new interpretations and the development of new targets. read full article…
Maximising drilling to define the mineral resource at the Nkout Iron Ore project
In September 2010, Afferro Mining Inc. commissioned SRK to conduct the maiden Mineral Resource Estimation (MRE) on their 100% owned greenfield Nkout Iron Ore project in Cameroon. The project is being managed by an SRK Qualified Person for iron ore projects. read full article…
Deciphering structural controls in a greenstone belt in Ghana
In March 2010, Xtra-Gold Resources Corp. commissioned SRK to conduct a structural geology analysis of their Kibi Project that aimed to provide insights to the geological and structural controls on the distribution of gold mineralisation and guide further exploration. read full article…
Project diversity and foreign interest spur SRK India’s growth and success
SRK established its Kolkata, India, presence in 2006. Since then, the office has expanded in response to client needs and an ever-growing client base. SRK India provides a range of services from auditing and competent-person reporting to exploration project advisory, drill program design, and sampling protocol implementation. read full article…
Integrating structural geology for improved resource modelling
SRK structural and resource geologists work closely with clients to deliver resource estimates that incorporate sophisticated geological and structural models. Since 2007, SRK has assisted Rainy River Resources Ltd. to develop detailed resource evaluations for the Rainy River deposit based on evolving, constrained structural models. read full article…
Effective geological training and data management
In recent years SRK Exploration Services noticed that the fast pace of modern exploration often occurs at the expense of quality data management and geological training. The current demand for experienced geologists shows little sign of abating and the need for training has never been greater. read full article…
Exploring for specialty metals in Greenland
In 2010, Ram Resources Ltd. commissioned SRK Exploration Services to assist with the review and acquisition of the Motzfeldt tantalum-niobium (Ta-Nb) project in South Greenland. read full article…
Advanced exploration targeting: SRK’s approach
SRK has a great deal of experience in assisting companies to implement minerals exploration programs from greenfields to advanced projects. The initial stage of any exploration program is targeting. read full article…
Cheap and dirty, but essential: geological/structural mapping
Having worked for SRK on a wide variety of exploration projects, I’m sad to report that geological and structural mapping continues to be a largely undervalued exploration tool in the industry. Finding a geological map in the display booths at explorer’s conferences is a bit like the industry itself: high risk – low gain! read full article…
Overview of uranium exploration and the nuclear industry in Argentina
Argentina’s long experience in the nuclear industry is evident not only in continuously generating electricity, 10% on average of Argentina’s national consumption since 1974, but also for the companies associated with the government-owned National Atomic Energy Commission (CNEA) that supply nuclear reactors for research and radioisotope manufacture for the international market. read full article…
New life for an old mine – Carmen, Chile
The Carmen iron mine is located in the northern Chilean Province of Chañaral and lies approximately 50km east of the coastal port city of Chañaral. Since May, 2010, Minera Santa Fe has been producing a dry magnetite iron concentrate from old stockpiles originally derived from the open pit, idle for 40 years. read full article…
Applying the box plot method
Since footwall alteration zones are related to volcanic-hosted massive sulfide (VMS) deposits, their unique features provide likely targets for exploration. Of these, the chloritic footwall alteration pipe is the most characteristic of VMS deposits. This feature is identified geochemically by a strong relative enrichment in aluminium and magnesium, coupled with depletion in calcium and sodium, giving rise to chloritic rocks. read full article…
The future of 3D modelling in consulting
Historically, SRK has been at the forefront of developing advanced geological and mine modelling methods from the early Gemcom days until the development of Leapfrog Mining with ARANZ. read full article…
