Landore Resources Limited: Soil Sampling Establishes Significant Anomolous Gold Along Strike From the BAM Gold Project Junior Lake Property14.01.2021 | 8:00 Uhr | CNW
LONDON, Jan. 14, 2021 - Landore Resources Ltd. (AIM: LND) ("Landore Resources" or "the Company") is pleased to report on the results of the 2020 soil sampling program carried out along strike to the east and west of its BAM Gold Project ('BAM Gold'), Junior Lake Property, Ontario, Canada. Highlights:
Commenting on this report, Chief Executive Officer of Landore Resources, Bill Humphries, said: "The highly successful soil sampling programmes, completed in 2020 and in 2019, has established the presence of widespread anomalous gold and multiple gold trends along strike to the east and west of BAM Gold for a total length of 8 kilometres. These programmes have identified numerous new drill targets which have the potential of being advanced into additional resources to continue the rapid growth of the BAM Gold Project. Drilling Update: 2020 SOIL SAMPLING PROGRAMME, JUNIOR LAKE PROPERTY Landore Resources' geological team completed an extensive exploration campaign during the summer of 2020 which included the establishment of a cut grid and soil sampling, westwards along strike for 2.1 kilometres and eastwards along strike for 2 kilometres from the existing BAM Gold Project, successfully establishing the presence of widespread anomalous gold and multiple gold trends. A full report on the 2020 soil sampling programme has been prepared by the Company (the "2020 Report"), with the key information from the 2020 Report summarised below. The 2020 Report containing maps and charts titled '2020 Soil Sampling Programme, Junior Lake property' and dated January 11 2020 can be viewed on Landore's website www.landore.com "Summary The Junior Lake property is located approximately 230 kilometres north-northeast of Thunder Bay, ON. The property contains three NI43-101 compliant mineral resources, two of which are predominately nickel (B4-7 and VW) and one which is gold (BAM Gold). During the summer of 2020 soil sampling was conducted on the Junior Lake property aimed at infilling and extending the 2019 soil sampling program (see soil report dated 30 November 2019). A total of 1013 samples, inclusive of QAQC samples were collected. Soil sampling consisted of collection of the B horizon at a nominal spacing of 25m. Numerous areas were unable to be sampled due to swampy conditions or signs of disturbance from past forestry operations. Soil data has indicated exploration targets prospective for further significant gold mineralization to the east and west of the currently-defined BAM Gold deposit. Numerous anomalous gold trends were noted, of which four priority areas are:
The soil sampling program was deemed a successful, low cost tool for gold exploration and should be expanded to cover the width of the property. Introduction The sampled portions of the grid spanned three separate areas:
A total of 1,013 samples, including 121 reference samples, were analyzed. Samples were collected from the B horizon at a nominal distance of 25m using a Dutch auger. Samples had their location recorded using a handheld GPS as well as the grid reference. Each sample also had the depth it was taken and description of colour and composition noted. The area was extensively logged ~20 years ago. As a result, areas with obviously disturbed soil, with thick organics or A horizons >2m, the limit of the soil auger, or conversely no developed soil profile, were not sampled. Property Description and Location The Junior Lake property is located ~230km north-northeast of Thunder Bay, ON and ~75km east-northeast of the village of Armstrong, Ontario. The property is accessible by heading east along gravel logging roads from the village of Armstrong. Regional Geology The Junior Lake property is located within the Caribou Lake – O'Sullivan greenstone belt of the East Wabigoon Subprovince of the Superior Province. The greenstone belt ranges from 3.5 – 15 km in width, north-south, and extends for 80 – 100 km, east-west (MacDonald, 2006). To the south it is bordered by the Robinson Lake Batholith of the Lamaune Batholitic Complex and to the north by a roughly east-west trending fault zone. Northeast of the property the belt is intruded by the tonalitic to quartz dioritic Summit Lake Batholith. Nipigon diabase sills and cross-cutting dykes intrude the western portion of the greenstone belt. Regional deformation is west to west-northwest trending and sub-vertical to steeply north dipping foliation and small scale folding. Metamorphism is generally greenshist, increasing to amphibolite near the contact of the batholiths. BAM Gold Deposit From 2015 to 2020 Landore has explored for gold on the property conducting multiple drill programs as well as ground geophysics, soil sampling and geological mapping. The Junior Lake property is host to the BAM Gold deposit reporting 31,083,000 tonnes (t) at 1.02 grams/tonne (g/t) for 1,015,000 ounces of gold including 21,930,000t at 1.06g/t for 747,000 ounces gold in the Indicated category (7 January 2020 Mineral Resource Estimate, National Instrument 43-101 ("NI 43-101") compliant). 2020 Soil Sampling The sampled portions of the grid spanned three separate areas:
A total of 1,013 samples, including 121 reference samples, were analyzed. Samples were collected every 25m using a 4 cm Dutch auger and placed in clean, brown paper bags specifically designed for this type of material. Samples had their depth of collection noted as well as a general description of the sample itself (see Appendix II). In areas of poor soil development composite samples, when possible, were taken using multiple holes. Once collected, samples were dried in camp before shipment to the laboratory. Duplicate samples were taken (4% of samples) and silica blanks were inserted (4% of samples). Replicate samples were taken at thirteen separate locations. The replicate samples consisted of three or four samples taken on an approximately 1 m x 1 m grid, where possible. A total of 1,013 soil samples were submitted to ALS Global Ltd. of Vancouver for analysis. The samples were analyzed for low level gold in soils and sediments. The analytical package used was 'Prep-41, Au Me-ST 43' which involves drying at <60oC and sieving to -180 micron followed by aqua regia digestion and ICP-MS finish for analysis of gold and 42 other elements. The samples submitted consisted of 893 individual soils, 49 duplicate soils, 24 replicate samples and 48 silica blanks. QAQC The duplicate samples taken correspond well. The majority of elements have 70-90% within +/-20% of the duplicate values, that increases to >90% of the values when the range is expanded to +/-30%. The outliers may in part be attributed to the sample sites. Numerous locations had thin B horizons which resulted in composite samples being taken. It is likely this contributed to the variation in duplicates. The replicate samples were taken at eight separate locations and consist of three to four samples on an approximate one meter by one meter square. Of the replicant samples, four of the sites had one sample of the replicant set with values greater than double the remaining samples while the other samples were within 20%. Three of the replicant sets had one sample >20% of the other samples. One set of replicant samples was within 20% for all samples. The variability may be a result of a different medium being sampled as often the sample description is different on the outlier sample. After review and consideration, the combined 2019-2020 data set was used for interpretive purposes. Soil Sampling Results To remove anomalous samples, they were screened based on their description. Samples described as organic rich, black or grey in colour or clay were considered suspect and may not be representative of the B horizon. The remaining samples were used for the calculation of the background value of each element. The background value is the average of the lower 25% quartile, listed in Table 2. Table 1: Select elements' calculated background values.
The response ratios (RR) were calculated for all elements by taking the background value and dividing it into the analytical value. This was also done for the suspect samples. RRs are rounded and values of >=5 considered anomalous. A correlation matrix was also generated for the samples taken. Gold (Au) showed only a very weak correlation with bismuth, and chromium. As a result, it was determined that use of the correlation matrix was not helpful at this time. An examination of the gold RR showed there were 103 samples with anomalous values (RR>=5). Of these samples 40 had values of 10-30 while 13 had RR >30. In order to help prioritize them a criterion of Au+As+Cu RR>5 was used. This criterion was previously established in 2019 as a signature of the gold mineralization of the BAM deposit. Seventeen samples were determined to have the same signature as the BAM deposit. Maps showing the anomalous sites for Au, As, Ag, Cu, Au+As+Cu are in Appendix I. As well a map illustrating the trend of the gold within the soil samples is in Appendix I. In order to assist in correlating anomalies across lines, the regional fabric of the area was used. Within the area there is a general fabric that strikes 105-115o, this is highlighted by completed geophysics (VLF, MaxMin). The geophysics highlights formation sulphide zones within the area and is used as both marker horizons and to illustrate the fabric within an area. It is important to note that there are cross cutting structures within the area. These structures may play an important role in the gold mineralization, acting both as pathways and aiding in concentrating the auriferous fluids. As such they will require additional investigation and follow-up in the future. To determine significant anomalies several elements with RR>=5 were examined, in particular Au, Ag, As, and Cu, with these elements often being closely associated with gold deposits. Criterion developed in 2019 established the combination of Au+As+Cu as being characteristic of the BAM deposit. Using this criteria, locations with coincident Au+As+Cu, and to a lesser extent Ag, anomalies were considered to have the same characteristics as the BAM occurrence and examined in detail. Seventeen sites were found with coincident Au+As+Cu anomalies, as well as thirteen additional sites with Au RR>30 of which selected locations are listed in Table 2.

Interpretation Gold appears to respond well to the sampling programs conducted in both 2019 and 2020. It is possible to link together anomaly trends across 100s of meters. It is important to not just rely on the intensity of the RR but to also use a multi-element classification. This is highlighted when the BAM occurrence is examined where multiple gram surface samples generate an Au RR of 5-6 in the immediate samples. This criterion is not meant to exclude single element Au anomalies. Through use of the soil data the BAM Gold trend was extended 1.1km to the west. Some exploratory diamond drilling has been conducted on a portion of this extension during fall 2020 and indicates the gold mineralization continues. Additional anomalies continue for ~1.5km and indicate that the trend may not only continue but indicates the presence of possible parallel, untested trends. To the east of the BAM Gold Deposit the trend has been extended for a further 2.0km. A portion of this area has already been sparsely drilled with encouraging results. Two parallel areas of interest, to the north and south, indicate the possible presence of addition gold horizons. These horizons may correlate to some of the anomalous trends to the west of the BAM Gold mineralization, indicating a possible second and third, untested mineralized horizon to the north and south of the BAM Gold deposit. Conclusions and Recommendations The 2020 soil sampling program was successful in generating several anomalies of interest as well as expanding on previously-generated anomalies. Exploration targets to the east and west of the currently-defined BAM Gold deposit are prospective for further significant gold mineralization. Gold is shown to respond well to the low-cost survey which has strong potential for future exploration. Recommendations:
From the soil sampling program there are four areas identified as priority targets:
End of Extracts Drilling Update-BAM Gold. To date, 30 drill holes have been completed for a total of 6,518 metres, with:
Considerable delays in receiving assay results are being experienced in the exploration industry world-wide due to the significant increase in drilling activity brought upon by the increase in metal prices, particularly gold. Consequently, ALS Minerals, one of the leading laboratories, has advised that a period of 7-8 weeks, from delivery of samples to the laboratory, is currently required for completion of full analysis. Drilling will recommence during the next week and is scheduled to complete in April.
