This is Our Earth, Our World, Ourselves.

This is our only Earth, our world. A simple phrase, yet as a geoscientist, it echoes a profound truth: we bear a timeless responsibility for the Earth and its inhabitants. But how do we truly claim this world as ours, beyond mere ownership? It begins with an inward journey, a fundamental understanding that our capacity for external change is directly linked to our internal state.

Consider this: can a turbulent mind truly foster peace in the world? Can a heart burdened with self-doubt truly extend compassion to others? Before we can heal the planet, we must first heal ourselves. Before we can extend a hand to a struggling neighbour, we must first offer kindness to the internal struggles within.

Imagine a garden choked with weeds. To cultivate vibrant flowers, we must first clear the debris. Similarly, we cannot purify our rivers if our minds are polluted with negativity. We cannot protect the rainforest if our hearts are consumed by internal conflict.

The spectre of global conflict, the chilling reality of nuclear power, has shown us the grim potential of collective destruction. Yet, we struggle to find a path to collective harmony. But while grand solutions elude us, individual action remains potent. We can begin by cultivating a culture of dignity, honouring our own inherent worth and extending that same respect to every person we encounter.

This isn't about lofty ideals; it's about practical steps. It's about pausing before reacting with anger, choosing empathy over judgment, and recognising the shared humanity that binds us. By tending to the garden of our own souls, we create a ripple effect, fostering a world where both people and nature can flourish.

Let us not simply claim this world as ours but actively create a world worthy of that claim!

 

Motels - Highway Stop Overs

Someone once said, 'The road is always better than the motel.' It's a sentiment that, upon reflection, unlocks a profound truth about a life well-lived. In my youth, like many, I chased aspirations, believing that reaching them would bring lasting satisfaction. But I soon learned that life is a continuous pursuit. Each achieved goal, a 'motel,' offers only a brief respite, a temporary pause on the endless road of self-fulfillment.

True creative living thrives on motion, on constant movement away from stagnation. The journey itself, the very act of trying, is where the true happiness lies. As an amateur photographer, the thrill isn't the albums or gallery display, but the moment of capturing the perfect shot. For me as a geologist, this road has taken many forms – the field exploration of minerals, the geological search and researches of precious metals, the countries and places visited, the people and multi-cultural experiences, and the lecture platform. Each 'motel' along these paths offered a moment for reflection, but also served as a springboard for new adventures.

The beauty of this journey is amplified when we travel not just through the external world, but also within the landscapes of our minds and spirits. We must diligently clear the dead ends of negativity, ensuring our internal compass points towards growth. The anticipation of self-fulfillment, the unwavering belief in our potential, transforms the road ahead into a vista of boundless possibility. Each step, each challenge overcome, strengthens the prospect of our greatest achievement.

Onion Skinned?

In today’s social media freedom, we know that some people are easily offended by perceived slights, requiring others to constantly monitor their words and actions.  This hypersensitivity often stems from low self-esteem.  Those with a fragile sense of self interpret seemingly innocuous remarks or actions as personal attacks, while individuals with healthy self-esteem are generally unfazed by such perceived slights.  Even genuine criticism, though potentially painful, has a far less devastating impact on someone with a strong sense of self-worth.  Conversely, those plagued by self-doubt and insecurity are prone to jealousy and perceive threats to their ego where none exist, often exaggerating the impact of even legitimate criticism.

Just as our physical bodies need the protective layer of skin, so too do our egos require a degree of resilience.  While a completely impenetrable shell would be detrimental, preventing us from experiencing the world fully, a lack of any protective layer leaves us vulnerable.  Many people navigate life with an overly sensitive "ego skin," reacting strongly to even minor perceived offences. They need to develop emotional resilience – a thicker "skin" – to deflect petty slights and perceived threats.

This resilience is built through cultivating self-esteem and developing a more positive self-image.  A physically strong person is less threatened by minor dangers than a weaker individual.  Similarly, a strong ego, bolstered by healthy self-esteem, is less likely to be threatened by innocent remarks or actions.  By building self-esteem, individuals can develop the emotional fortitude needed to navigate social interactions with greater confidence and less vulnerability.

First Journey to Kabul, Afghanistan

NOTES FROM MY DIARY

30 April 2014 @ Melbourne

Today, I embarked on a journey to Dubai, the first step in obtaining my Afghan visa where I am to work as Senior Geologist for the USAID’s project called MIDAS (Mining Investment and Development for Afghan Sustainability).

My flight, Singapore Airlines, SQ408, from Melbourne to Dubai, was scheduled to depart at 6:20 PM.

The morning was a flurry of activity spent finalizing travel preparations. Telly kindly brought Ampy to work while I finalized my packing. After sending a few emails and relocating the Apple MAC computer from the study to the studio, Telly and Ampy returned to drive me to Tullamarine Airport. Thankfully, I had completed the online check-in the previous evening, streamlining the airline departure process.

Everything went smoothly at the airport; check-in was hassle-free, and I boarded the plane, securing my seat in 57D. Unfortunately, the flight was far from peaceful. A family – a mother, a boisterous four-year-old daughter, a crying two-year-old son, and a grandmother – was seated nearby. The constant cries of the young child were particularly disruptive, and the situation was further compounded by the child's parents' request to use the empty seats beside me. Despite the inconvenience, I couldn’t refuse. Unfortunately, the disruptions continued throughout the night, including the unpleasant odour of multiple diaper incidents.

Despite the noise, I managed to enjoy the in-flight meals and passed the time by watching "I, Frankenstein" and "Jack Ryan: Shadow Recruit." However, the pilot's announcement of a 7-hour and 20-minute flight, longer than anticipated, cast a shadow over the smooth journey. This unexpected delay meant I would miss my connecting flight in Singapore. As scenarios raced through my mind, I resolved to build in at least two hours of layover time for future connecting flights to account for potential delays. For now, there was nothing to do but relax and hope for some sleep.

 

1 May 2014 @ Singapore – Layover

As expected, plane was delayed. The flight arrived in Singapore at 12:25 AM, and I exited the terminal around 12:35 AM. Panic set in when I realized my connecting flight's boarding time was at 12:10 AM! I braced myself for the inevitable chaos and headed to the information counter.

Anticipating potential travel chaos, to my astonishment, the agent informed me the gate was still open for my flight. Confused, as I hadn't seen SQ498 on the monitor, she directed me to Terminal 2, Gate E11.

The race against time began. I sprinted through Terminal 3, hopped on the Skytrain, and continued running towards Terminal 2. Grabbing a trolley was a lifesaver. The frantic dash to the gates felt like a high-stakes reality show (The Amazing Race), and I was the sole contestant that my body was screaming for mercy.

Miraculously, I arrived at the gate just as the last passengers were clearing security. Exhausted but elated, I boarded the plane and claimed my aisle seat, 57H. Unfortunately, my seat neighbour had a strong body odour, making for an unpleasant start to the flight.

I attempted to distract myself with movies but found little enjoyment in "Invisible Woman" and couldn't muster the enthusiasm for other options. Sleep became my only refuge.

Dubai, UAE

My flight arrived in Dubai on time at 4:45 AM. Navigating the massive airport, I spent ten minutes clearing immigration and customs, both of which were surprisingly hassle-free compared to my usual experiences. The process was far less stringent than I expected, with no forms to fill up or questioning by an immigration officer. The relaxed atmosphere was a pleasant surprise. A good sign to have a pleasant day ahead.

I took a taxi to the Le Meridien Airport Hotel, paying AED60. I arrived at the hotel by 8:00AM, and unfortunately, no rooms were available until 10 AM. While waiting, I recharged my Vodafone phone for AED50, giving me an AUD75.73 credit. I contacted Bismilla the travel agent at Skylink Travel who is arranging my visa. I also sent an SMS to update Ampy and Telly.

Waiting isn’t my strong suit, and the hours until the room check-in felt interminable. The constant Nokia ringtones in the lobby were grating. A Sony Xperia ad with dual SIM card caught my eye, a very tempting prospect.

After what felt like an eternity, I finally got a room at 10 AM, only to be disturbed by two false fire alarms caused by someone smoking in the stairwell. To top it off, I discovered an error on my newly issued visa: my birthplace was listed as Australia instead of the Philippines.

All of these, I say it is an initiation to working in a conflict zone – Afghanistan. I wonder what the future holds. I wish myself luck.

2 May 2014 - Dubai to Kabul

Today I take my first trip from Dubai to Kabul.

The High Stakes of Sample Size in Ore Classification - How One Sample Can Impact Mine Profitability

Traditionally, a single sample can determine the fate of a large volume of material in a mine. This decision, often involving tonnes of ore or waste, hinges on the accuracy of that one sample. This reliance on a limited data point presents a significant cost risk.

To illustrate, consider the impact of sample size on mine tonnage. During my time as Chief Geologist at the Longos Gold Mine, the open pit in Paracale, a single sample represented 7 tonnes of in-situ material. A misclassification could lead to incorrectly categorizing this material, resulting in lost revenue (if ore is classified as waste) or unnecessary processing costs (if waste is classified as ore).

Quantifying the Impact:

Let's consider the economic consequences of such a misclassification. Assuming the average gold content per tonne of ore is X grams (g) at a price of Y dollars per gram ($/g), the potential financial loss due to a misclassified 7-tonne batch would be:

• Loss from discarded ore: (X g/tonne * 7 tonnes) * ($Y/g) = Z dollars
• Additional processing cost for waste: (processing cost per tonne) * 7 tonnes = W dollars
• The total potential cost (Z + W) highlights the importance of using an appropriate sample size to minimize misclassification risks.

Moving Forward: A Data-Driven Approach

This example highlights the high stakes associated with limited sample size. Implementing statistically robust sampling techniques, such as collecting multiple samples, can significantly reduce the economic risk impact of misclassification and improve overall mine profitability.

Are Diamonds Still Girls' Best Friend?

"Diamonds! Diamonds!

I don't mean rhinestones!

...

But square-cut or pear-shaped

These rocks don't loose their shape.

Diamonds are a girl's best friend."

The above lyrics composed by Jule Styne and sung by Marilyn Monroe still lingers on. Diamonds have always been said to be a girl’s best friend. But coming from a geoscience background, I believe it is a matter of popular perception that makes it their best friend of choice. 

Don’t get me wrong, I am not debasing diamonds. They are precious stones, and their value has stood the test of time. The gems properties are an excellent brilliant lustre, the hardest known mineral, priced and loved by most women… and some men. 

The question to ask is, “Is it rare?” The answer is “no.” Diamonds are commercially abundant. Good jewellery stores carry stocks of them. But, why does it have to be rare? Because rarity makes it worth having and truly precious. There are rare varieties like the Argyle pink and yellow diamonds. However, there is a jewel that is even rarer – ruby! This can be evidenced by browsing your local jewellery advertising brochures. What you will find in those brochures are diamond jewellery but not ruby jewellery. If there are any, it would say “created, man made or industrial” rubies. “Natural” rubies are indeed rare! 

My wife who is also a geologist, and quite knowledgeable on gemstones, if presented with a diamond and ruby, she would obviously take both. But, if made to choose one over the other, ruby is her definite choice. During my last trip to South Africa, I was told to buy her Tanzanites. Yes, tanzanite is another rare gem, found only in Tanzania, East Africa, thus proving her adeptness of gemstones. Another requirement is that the jewellery is to be set in platinum. Platinum is her choice of base setting as it is rarer, stronger and more valuable than gold. Now with choices of Ruby, Tanzanite in a platinum setting, the question is, “Are diamonds still a girl’s best friend?” You decide, the answer is obvious!

Data Management

It has been referred to in many publications that an organisation’s most important resource is its data. In recent years the worldwide exploration and mining industries has rigidly emphasised the need for QA/QC with the development of standard reporting codes to meet industry best practice. Understanding how data relates to information to form the big picture enables an organisation to make better decisions, improve process efficiencies, and lower overall operational costs. In today’s highly competitive market, without an adequate understanding of the importance of an organization’s data and its structures, it would be a challenge to enable effective decision-making and provide an overall view of what is happening, both within and outside the organization. 

Recently I read Russell L Ackoff’s book entitled “Re-Creating the Corporation: A Design of Organizations for the 21st Century.” In his book, Ackoff posited a tier, from top to bottom, of wisdom, understanding, information, knowledge, and data. He also estimated that on the average human mind consists of 40% data, 30% information, 20% knowledge and 10% understanding and almost no wisdom. Ackoff’s model can be viewed as a pyramid with wisdom on top. In Figure 1, I have taken Ackoff’s idea and expanded it to cover the data source, and omitted understanding, placing it as an encompassing behaviour to management of data.

Figure 1: DATA, PROCESSING & MANAGEMENT

It can be summarised that data is a collation of facts, data that has been analysed will give you information, the use of information will give you the knowledge, and the maximisation of this knowledge will result in wisdom. Furthermore, the increase in understanding can shed light on facts to obtaining knowledge, and through experience we can attain wisdom. 

The simple chart above shows the interrelationship between the different degrees of data and it is about filtering noise, reducing the flow to what is clear, clean and manageable as a corporate resource. These interrelationships are not as simple as portrayed in real life. It can be more complicated than a mere flow process. Consider the following observations made by Neil Fleming (Coping with a Revolution: Will the Internet Change Learning?, Lincoln University, Canterbury, New Zealand, 1996):

• A collection of data is not information.
• A collection of information is not knowledge.
• A collection of knowledge is not wisdom.
• A collection of wisdom is not truth.

Thus, a mere collection of data is not of full value to an organisation. In our consulting assignments, we at Mining Plus, have encountered from good to bad client databases at various stages of development. It is one of our core strengths to create, audit, manage and add value to our client’s most valuable resource; data that is truthful and validated. If your company deals with data, them come and see us.
