Minera Alamos Inc. (TSX-V:MAI) is pleased to report the initial results from its Phase 1 drill program at the Santana gold project, Sonora, Mexico. The 2018 drill program is the first exploration drilling to be conducted at Santana since 2011. The first three holes were drilled near or within the Nicho deposit and were intended to evaluate mineralized extensions of previous exploration programs. All drill holes encountered zones of disseminated gold mineralization. Initial results support the Company’s long held belief that there are numerous exploration targets in the Santana project area that could add significantly to the ongoing development plans of a proposed heap‑leach operation currently awaiting receipt of commercial-scale permits from the Mexican authorities (see release dated July 26th, 2018).
“In addition to near-term production potential, a criteria for all of the projects in the Company’s development portfolio is that the concession areas contain significant exploration upside. While we have been aggressively pursuing production permits our exploration team has been working in parallel to expand geological models and target high priority areas for resource expansion potential.” stated Darren Koningen, CEO of Minera Alamos. “These very encouraging drill results at the Santana project are the start of an ongoing exploration program designed to demonstrate the significant untapped value contained in our development assets”.
Hole S118-116 was a step-out hole to assess the continuity of the southwest mineralization in the main Nicho zone (see Figure 1). The hole returned 93.5m of 0.65 g/t gold starting from just below the topographic surface. The application of a typical open pit heap leach cut-off grade of 0.15 g/t results in +60 m of mineralization containing approximately 1 g/t gold (see Table 1).
Holes S118-114 and S118-115 were targeted to examine a satellite zone of gold mineralization located immediately to the northeast of the Nicho deposit and its potential continuity with the main gold system. Both holes intersected multiple zones of gold mineralization. The new data is currently being interpreted in the context of the updated geological model for the deposit and the area will be the target of follow-up efforts as part of the Phase 2 drill program.
The Phase 1 drilling program has now concluded with the completion of ten holes totalling approximately 1500m. The remaining holes yet to be reported include further testing of the southwest extensions of the Nicho deposit (see figure 2), in advance of mine planning activities in addition to new zones of mineralization located north of the main Nicho deposit.
Table 1 – Mineralized intervals from 2018 Santana Project drill program.
|Mineralized Interval 1,2||Composite Interval 3|
|Drill Hole||From (m)||To
|1.||Grades/widths of mineralized intervals represent complete “from” “to” drill depths as shown.|
|2.||All holes were drilled at 45-60 degree inclinations designed to be roughly perpendicular to the estimated dip of mineralized structures. Based on current understanding of the geological structures, true widths of the mineralized zones are expected to be 80-90% or greater of the drill widths outlined in the table above.|
|3.||Grade/width of composite intervals is a total of all mineralized intervals that have gold grades equal to or in excess of “typical” open pit mining heap leach cut-off grades of 0.15 g/t gold.|
Assay results are pending from the remaining seven holes and the results, as well as addition geological interpretations will be released as they are received over the coming weeks. All diamond drill samples were collected by Minera Alamos personnel including the company’s exploration geologists. Drill core samples were cut in half and divided into 1-2 m intervals. One half of the sample was bagged for analysis and the remaining half was logged by Minera Alamos personnel and stored for future reference. Blanks, duplicates and standards were randomly inserted with the samples sent for analysis as part of the normal QA/QC procedures.
All samples were prepared and analyzed for gold using fire assaying with AA/gravimetric finish. All samples were sent for sample preparation at the ALS-Chemex facility in Hermosillo, Mexico.
