The Australian Synchrotron Imaging and Medical Beamline (IMBL) uses a superconducting multipole wiggler (SCMPW) source, dual crystal Laue monochromator and 135 m propagation distance to enable imaging and computed tomography (CT) studies of large samples with mono-energetic radiation. This study aimed to quantify two methods for CT dose reduction: wiggler source operation at reduced magnetic field strength, and beam modulation with spatial filters placed upstream from the sample. Transmission measurements with copper were used to indirectly quantify the influence of third harmonic radiation. Operation at lower wiggler magnetic field strength reduces dose rates by an order of magnitude, and suppresses the influence of harmonic radiation, which is of significance near 30 keV. Beam shaping filters modulate the incident beam profile for near constant transmitted signal, and offer protection to radio-sensitive surface organs: the eye lens, thyroid and female breast. Their effect is to reduce the peripheral dose and the dose to the scanned volume by about 10% for biological samples of 35–50 mm diameter and by 20–30% for samples of up to 160 mm diameter. CT dosimetry results are presented as in-air measurements that are specific to the IMBL, and as ratios to in-air measurements that may be applied to other beamlines. As CT dose calculators for small animals are yet to be developed, results presented here and in a previous study may be used to estimate absorbed dose to organs near the surface and the isocentre.

Golden Cariboo Resources Ltd. (GCC:CSE; GCCFF:OTC; A0RLEP:WKN; 3TZ:FSE) has reported encouraging results from its 2024 field campaign. During the exploration, the company collected 16 rock samples from the Halo zone, North Hixon zone, and Pioneer area. These samples revealed promising gold mineralization in the region. Notable highlights from the Halo zone include grab samples from newly exposed outcrops, with assays reaching 8.47 g/t Au (grams per tonne, gold), 6.59 g/t Au, and 2.39 g/t Au. These samples were taken from altered andesite tuff with quartz-carbonate veins located approximately 101 meters northeast of the nearest drill collar.

Sampling near the Pioneer showing, situated one-kilometer north-northwest of the Halo zone, also returned assays of 1.13 g/t Au and 0.40 g/t Au. The fieldwork's findings have significantly extended the strike length of known gold mineralization by one kilometer and expanded the surface footprint of mineralization to the northeast. Despite challenging glacial cover, Golden Cariboo's team continues to uncover significant gold-bearing outcrops.

The report also underscored the strategic advantages of the property's location, infrastructure, and proximity to Highway 97, which reduces exploration and operational costs. Wortel detailed Golden Cariboo's drilling campaign, which includes results such as Hole QGQ24-013, which intersected 136.51 meters at 1.77 g/t gold, including a higher-grade interval of 23.89 meters at 3.32 g/t gold.

Valuation metrics from the report included a projected fair value of CA$0.40 per share, representing a 74% potential upside from the current trading price of CA$0.23, and doesn't include the added value from recent, significant exploration success. Despite acknowledging the high risks associated with early-stage exploration projects, Couloir Capital emphasized the long-term value potential in a Tier 1 mining jurisdiction, reinforced by the company's experienced management team and promising geological trends.

Frank Callaghan, President and CEO of Golden Cariboo, stated in the news release, "Although there is a lot of glacial cover on this project, our geologists still managed to find new gold-bearing outcrops in areas of great significance. We have now expanded the surface footprint of gold mineralization at the Halo zone to the northeast and increased the strike length of our gold trend. We're in a very large gold system that is being demonstrated by multiple, varied work programs."

Mining and Metals Market

On October 29, Kitco reported that gold prices had reached nearly US$2,800. This price represents a 35% increase for the year. The rise was attributed to multiple factors, including "geopolitical conflicts, Federal Reserve interest rate normalization, continued strong demand from global central banks, and uncertainties about the upcoming presidential election and potential fiscal stimulus." Analysts at Kitco described this combination of elements as a "perfect storm." They noted it had driven investor sentiment and reinforced gold's value as a hedge against economic turmoil.

LiveMint, on October 30, highlighted the substantial returns seen in gold over the past year. Despite this impressive performance, some analysts expressed caution regarding gold's future trajectory. Ajay Kedia, Director of Kedia Advisory, suggested that while gold prices may see a short-term rally, "investors may have to remain cautious on the yellow metal in the second half of 2025." Kedia noted that gold prices could experience profit-taking and a slowdown if interest rate cuts by the Federal Reserve do not materialize as quickly as expected. Nonetheless, gold has continued to serve as a preferred asset for those seeking stability, especially in times of economic and political uncertainty.

In a November 4 report, Egon von Greyerz, Founder and Chairman of Matterhorn Asset Management, provided a historical perspective on gold's role in preserving wealth. Von Greyerz discussed how gold had consistently retained value, even as fiat currencies depreciated over time. He emphasized, "Gold held in the investor's name in safe vaults and jurisdictions outside the financial system is the ultimate form of wealth preservation." Von Greyerz also pointed to gold's outperformance since the 1970s, stating that gold had increased 78 times since President Nixon ended the gold standard in 1971. He argued that gold's journey was "only starting now," citing the ongoing destruction of fiat money value through global debt expansion and monetary policies.

Cariboo Catalysts

According to Golden Cariboo Resources' Q1 2024 investor presentation, the company is advancing exploration on its 3,814-hectare Quesnelle Gold Quartz Mine property, located in British Columbia's historic Cariboo Mining District. The asset benefits from 160 years of mining history and is road-accessible, facilitating year-round exploration. The 2024 exploration program, including trenching and a proposed 2,500-5,000m Phase 2 drilling campaign, aims to delineate the gold system further and complete a National Instrument 43-101 compliant resource estimate.

The property, encircled by Osisko Development Corp. on three sides, holds the potential for high-grade, multi-ounce gold targets. Management is focusing on a multi-phase exploration strategy. This includes trenching to assess shallow overburden and mapping and sampling to refine drill targets. The team's experience and the property's historical and geological significance position Golden Cariboo as a promising exploration venture.

The proposed drilling and development efforts reflect a systematic approach to unlocking value in this underexplored yet historically significant gold camp as the company progresses toward realizing a resource estimate.

Expert Analysis

Golden Cariboo Resources Inc. received favorable coverage from Couloir Capital in a report released on September 3, 2024. Senior Mining Analyst Ron Wortel issued a Buy recommendation for the company, noting the significant potential for discovering a large gold resource at the Quesnelle Gold Quartz property. Wortel highlighted that the property, located in British Columbia's historic Cariboo Mining District, lies along the same geological trend as Osisko Development's projects, suggesting the possibility of tapping into similar high-grade mineralization systems.

The report also underscored the strategic advantages of the property's location, infrastructure, and proximity to Highway 97, which reduces exploration and operational costs.

Despite the racial reckoning going on in America right now, and despite the fact that attitudes towards race, inclusion and representation are different now than they were 30 years ago, new research from UC Berkeley shows that a large majority of American metro areas are more segregated now than they were in 1990. The new report from Berkeley’s Institute covers a number of topic areas, but among the key findings were from the national segregation report component of the project, which found Los Angeles to be the sixth-most segregated metro area with more than 200,000 people.

Today on AirTalk, we’ll talk with the lead researcher on the new report and a local historian to talk about how we see the findings of the report play out in Southern California.

A National Science Foundation-funded research has discovered the root cause of why lithium metal batteries fail -- bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access. The discovery challenges the conventional belief that lithium metal batteries fail because of the growth of a layer, called the solid electrolyte interphase (SEI), between the lithium anode and the electrolyte. The researchers made their discovery by developing a technique to measure the amounts of inactive lithium species on the anode -- a first in the field of battery research -- and studying their micro- and nanostructures. The findings could pave the way for bringing rechargeable lithium metal batteries from the lab to the market.

Users get a Twitter-like microblogging experience, according to screenshots provided to media, suggesting that Meta Platforms has been gearing up to directly challenge the platform after Musk's tumultuous ownership has resulted in a series of unpopular changes that have turned off users and advertisers.

Meta's Threads racked up more than 30 million sign-ups within about 18 hours of its launch, emerging as the first real threat to Elon Musk-owned Twitter, as it took advantage of its access to billions of Instagram users and a similar look to that of its rival.

The bank provides an immersive 3D experience for customers to perform traditional banking activities using their digital avatars.

New data apps tracking firm Sensor Tower indicates the hype has died down and Threads has seen a 20% decrease in active users and a 50% reduction in time spent on the app, from 20 minutes to 10 minutes.

Meta has been designing prototypes for chatbots that can have humanlike discussions with its users, as the company attempts to boost its engagement with its social media platforms, according to the report, citing people with knowledge of the plans.

The success of Threads raises questions about Twitter's future. Amid massive layoffs and declining ad revenue, Twitter faces a turbulent time, further exacerbated by Elon Musk's renaming of the platform to X.
