Industrial Heavy Minerals Expert Consulting Sampling and Analytical Services

The vendor is required to provide industry leading industrial heavy minerals (HM) integrated “one-stop-shop” expert consultant contractor that can provide expert advice, exploration, laboratory-analytical services, and sample processing for industrial HM and gold placers.
- Provide the entire suite of consulting, exploration, sample processing, and analytical services for industrial HM placers needed and required by international mineral resources reporting standards and codes for HM placer projects.
- Five mission-critical services to office projects are required:
1. Field exploration support:
• Analyses of sediment cores to determine and document the geologic evolution of surficial and subsurface sediments on prospect scale.
• Work includes planning, staffing, supervising, and guiding core-drilling activities.
• The contractor shall direct, supervise, conduct, log drilling and recovery of about 2,000 10-foot long 6” diameter sonic core samples.
• These bulk samples must be sampled, on-the-spot analyzed, and splits removed for laboratory analyses.
2. Laboratory and analytical support:
• On site identification, selection, bagging and tagging samples for a) archiving, b) laboratory HM analyses, and c) pm assays.
• Work includes sedimentological descriptions and photographic documentation of core sections representing about 10 feet each to variable depths.
• Work includes metallurgical studies and test including work sieve analyses (bulk, spiral con, spiral rejects, hl sink, hl float, mag fractions, and etc.), hl (including of “pixie dust” fractions by centrifugation), magnetic separation, modal mineralogical composition, XRD, XRF, SEM, microprobe, and etc. analyses as agreed to.
• Analyses must include pm (au, PT, pd, rh) analyses by BLEG, SEM, microprobe, fire assay, ICP-MS, INAA, and other analyses as appropriate and as agreed to by agency project manager.
• Four (4) Deister concentrators (six preferred) with wet and dry feed metered mechanisms 
• One (1) Wilfley laboratory table concentrator with wet and dry feed metered mechanism 
• One (1) Knelson laboratory Centrigugal bowl batch mineral separator (CVD unit preferred) with dry and wet feed metered mechanisms. 
• Three (3) Frantz laboratory barrier magnetic mineral separators with regulated power supplies; two with low field controllers. 
• One (1) Frantz isodynamic magnetic mineral separator with regulated power supply, configured for free-fall separation mode with metered dry-feed mechanism.
• One laboratory roll magnet separator with variable field strength, controlled by regulated power supply, with dry metered sediment feed control. 
• Two rotary helical hydro gravimetric HM recovery concentrators 
• One 3.5-turn molded-rubber-lined Humphrey mineral separation spiral with dry and wet feed mechanisms. 
• One mt model md3 test spiral with class splitter and dry and wet regulated feed mechanism. 
• One 12-turn, triple-feed spiral mineral concentrator with 3-way product splitter and 100kg or HR wet and dry screw-feed mechanism. 
• Two long-tom sluice mineral concentrators 
• 50 sample per shift hl separation capacity lab furnishing with 500ml glass separatory funnels for LMT heavy media separations, densitometers, high-capacity evaporator LMT recovery system.
3. Mineral resources assessment support:
• Custom-tailored laboratory sample preparation methods and analyses will qualify and quantify HM and pm in sonic core intervals. 
• Provide in-field orientation and training to staff. 
• Resultant mineralogical, textural, and mineral-chemical data shall be integrated with adjunct geological, geophysical, etc. data to produce a report on the magnitude and nature of placer mineral resources at grinder. 
• Work includes professional consultative services on demand, documents suitable for publication, referrals to subject-matter experts, and referrals to funding and mining enterprises.
4. Laboratory visit and independent sampling by chief geologist:
• The agency project manager will visit contractor’s main laboratory facilities twice per year to conduct independent sample processing and analyses. 
• Work will include microscopy, modal mineralogy, mineralogical determination, hl, tabling and magnetic separation of HM and pm placers. 
• Provide the agency project manager with necessary equipment and training if required.
5. Marketing:
• Documentation and market development of industrial mineral species, traditional and non-traditional HM, abrasives etc.
• The contractor must provide climate-controlled secure storage services for samples.
